Invited Talk: Probing Many Body Quantum Systems by Matter Wave Interference
Jörg SchmiedmayerVienna Center for Quantum Science and Technology (VCQ), Atominstitut, TU-Wien Interacting many body quantum systems, their dynamics and relaxation, are at the centre of many interesting physics problems ranging from particle creation in the early universe to the properties of quantum materials.Ultra-cold atoms are a model system to build quantum many body systems and study their description by quantum fields in the lab. In this talk I will give an overview of the different possibilities interference experiments offer to probe many body systems and their underlying quantum description.In a first set of experiments, we look at a quench which splits a single one-dimensional system (quantum field) into two parallel…

Invited Talk: Quantum Gases in Space for Fundamental Physics and Earth Observation
Naceur Gaaloul Leibniz University of Hannover, Germany Space-borne quantum technologies and more particularly atom-based devices are announcing a new era of strategic, intense space exploitation. Indeed, space offers a unique environment characterized by low noise and low-gravity necessary for a wide spectrum of applications ranging from time and frequency transfer to Earth observation and the exploration of fundamental laws of physics.In this contribution, we report about two recent mission concepts based on the use of quantum-gas sensors. The first is the satellite mission Space-Time Explorer and QUantum Equivalence Principle Space Test (STE-QUEST), currently a phase-2 candidate for the M7 launch opportunity of the European Space Agency’s science programme. STE-QUEST, with…

Hartmut Abele
Hartmut Abele at TU Wien has wide experience in high precision experimentation using thermal, cold and ultra-cold neutrons. The neutrons are investigated both in-beam, or confined in traps, with the aim to test fundamental interactions and symmetries. The current research focus is on the relationship between gravitation and quantum mechanics. As the pioneer in the field, the Vienna group is able to drive resonant transitions between quantum states in the gravity potential of the earth. By implementing this gravitational resonant spectroscopy technique to measure the discrete energy eigenstates of a bouncing quantum particle, the method provides a constraint on any possible hypothetical gravity-like interactions on that level of accuracy, which…

Invited Talk: Observation of a gravitational Aharonov-Bohm effect and its implications for quantum superpositions of Newtonian gravitational fields
Mark KasevichStanford University, USA The gravitational interaction of a tungsten source mass with atomic wavepackets has been observed in an atom deBroglie wave interferometer, in a regime where the separation distance between the interfering wavepackets is comparable to their distance to the source mass. We will discuss this experiment in the context of Aharonov-Bohm effects. We will describe the relevance of these results to observation of quantum superpositions of Newtonian gravitational fields.

Invited Talk: Persistent currents for ultracold fermions on a ring
Anna MinguzziCNRS and Universite Grenoble Alpes, LPMMC, Grenoble France We study the persistent currents of an interacting Fermi gas confined in a tightly confining ring trap and subjected to an artificial gauge field. For attractive interactions, we study the currents all through the BCS-BEC crossover. At weak attractions, on the BCS side, fermions display a parity effect in the persistent currents, i.e. their response to the gauge field is paramagnetic or diamagnetic depending on the number of pairs on the ring. At resonance and on the BEC side of the crossover, we find a halving of the periodicity of the ground-state energy as a function of the artificial gauge field…

Invited Talk: Clock Atom Interferometry and Floquet Atom Optics
Jan Rudolph,1 Thomas Wilkason,2 Megan Nantel,2 Yijun Jiang,2 Benjamin E. Garber,1 Hunter Swan,1 Samuel P. Carman,1 Mahiro Abe,1 and Jason M. Hogan11Department of Physics, Stanford University, Stanford, California 94305, USA2Department of Applied Physics, Stanford University, Stanford, California 94305, USA Clock atom interferometry (AI) describes the coherent manipulation of an atomic two-level system separated by an optical frequency difference. It makes use of narrow transitions to metastable statescommonly used in optical atomic clocks. In contrast to conventional AI, such transitions can be driven resonantly using a single laser beam, which has promising implications for the suppression of laser frequency noise [1], a fundamental limitation for some of the most challenging applications…

Invited Talk: One-minute coherence in an optical-lattice based atom interferometer
Holger MuellerUC Berkeley In quantum metrology and quantum information processing, a nonclassical state must undergo a quantum process before unwanted interactions with the environment lead to decoherence. In atom interferometry, the nonclassical state is a coherent spatial superposition of partial wave packets and the process might be, e.g., accumulation of sufficient phase shift to allow detection of extremely weak interactions, such as the gravitational field of a small proof mass. The coherence in atomic fountains is limited by the available free-fall time in Earth’s gravitational field. This can be overcome by suspending the wave packets in an optical lattice, which has so far reached up to 20 s of coherence,…

Invited Talk: Joint mass-and-energy test of the equivalence principle with atom interferometers
Ming-Sheng Zhan11Wuhan Institute of Physics and Mathematics, Innovation Academy for Precision Measurement Science and Technology, Chinese Academy of Sciences, Wuhan 430071, China The equivalence principle (EP) is a basic assumption of the general relativity. Quantum test of EP with atoms is an important way to examine the applicable scope of the current physical framework, so as to discover new physics. Recently we improve the four-wave double-diffraction Raman transition method (4WDR) [1] we proposed before to select atoms with a certain mass and angular momentum state, and form a dual-species atom interferometer. By using the extended 4WDR to 85Rb and 87Rb atoms with specified mass and internal energy we carry out…

Yuji Hasegawa1,21Atominstitut, TU-Wien, Stadionallee 2, A-1020 Vienna, AUSTRIA2Division of Applied Physics, Hokkaido University, Sapporo, Hokkaido, 060-0808, JAPAN Neutron interferometers provide ideal situations of experimental observations of interference between coherently split, well-separated beams of matter waves, in this case neutron de Broglie waves. Interferometers made of perfect silicon crystal was invented for x-rays in 1964 and first performance with neutrons was confirmed by Rauch, Treimer and Bonse at the Atominstitut, Vienna in 1974. The Atominstitut was distinguished as an European-Physical-Society (EPS) Historic Site on 22 May 2019. Over the past almost half century, neutron interferometer experiments are bringing impact on fundamental quantum and neutron physics [1-3].Since the time-independent Schrödinger equation, i.e.,…

Invited Talk: Superfluid quantum Bose gas on a shell
Hélène PerrinUniversité Sorbonne, France Quantum gases provide us with a very convenient and widely tunable system for the study of superfluidity. In particular, they can be confined in a large variety of geometries (harmonic traps, optical lattices, box traps, lower dimensional traps…), enabling the study of superfluid dynamics with specific constrains. In this talk I will present the behaviour of a superfluid quantum gas confined at the surface of an ellipsoid: the atoms can move freely in directions parallel to the surface and are strongly confined in the transverse direction. In a first series of experiments, the atoms initially at rest at the bottom of the shell -because of gravity-…

Invited Talk: Determination of the fine-structure constant using atom interferometry

Among them, the fine structure constant which characterizes the strength of the electromagnetic interaction and thus plays a crucial role in quantum electrodynamics calculations. Using atom interferometry to measure the quotient ħ/mRb of the reduced Planck’s constant and the mass of a rubidium-87 atom, we obtained the most accurate determination of the fine structure constant α=1/137.035999206(11) with…

Invited Talk: Quantum control of an array of optically levitated nanoparticles
Uros DelicUniversity of Vienna The field of quantum optomechanics aims to exploit light-matter interaction in order to realize macroscopic quantum states of massive solid-state mechanical objects. Within optomechanics, optically levitated dielectric nanoparticles have emerged as a promising platform for tests of fundamental physics, development of novel sensing techniques or investigation of complex non-equilibrium physics. Optical trapping provides unique possibilities for quantum state preparation, for example through engineering of dynamic and nonlinear optical potentials. I will discuss recent experimental advances in levitated optomechanics, such as the motional quantum ground state preparation [1] and the observation of non-reciprocal optical interactions between two nanoparticles [2]. The rapidly developing control toolbox allows us to…

Invited Talk: From new ways of free electron control to the coherence of multi-electron pulses
Peter HommelhoffUniversity of Erlangen, Germany Electric and magnetic fields generated from microstructures allow complex field configurations. We use this approach to build chip-based guides, i.e. two-dimensional Paul traps, for free low-energy electrons (1 eV to keV level). In addition, we have demonstrated guided electron beamsplitters and other elements, ideally suited for matter wave experiments with electrons. In the second part of the talk, I will show that fully coherent electron beams can be easily generated from needle tip emitters, including coherent electron pulses with femtosecond time resolution. Because of the charged nature of the electrons, their coherence is reduced even for a mean number of 1 electron per pulse due…

Invited Talk: Creating a massive minimal uncertainty wavepacket using Gross-Pitaevskii breathers
Maxim Olshanii (Olchanyi)University of Massachusetts Boston We assess the difficulties in creating a provably coherent quantum state of a relative motion of two bosonic solitons using Gross-Pitaevskii breathers. The scheme for creating such state-a four-fold quench of the interactions applied to a bosonic soliton is not new. However, an experimental proof of a macroscopic coherence is difficult. Our proposal is to suggest a protocol where variances of the relative distance and the relative momentum are experimentally accessible: then whenever the product of the two gets close to the Heisenberg uncertainty limit, such state can be declared to be coherent. We present an extensive numerical study on the subject.The projects are…

Contributed Talk: State-dependent potentials for trapped atom interferometry
Thomas Fernholz1, Vilius Atkocius1, Rhys Morrison1, and Jamie Johnson1 1(Presenting author underlined) School of Physics & Astronomy, University of Nottingham,NG7 2RD Nottingham, UK Atom interferometry does not necessarily require free propagation of matterwaves, be it in free-space or along a waveguide. The example of Sagnac interferometry with fully trapped atoms in state-dependent trapping potentials [1] will be discussed, advantages and disadvantages, as well as our efforts for animplementation. Recently, radio-frequency dressing allowed us to demonstrate state-dependent guiding of different rubidium hyperfine states in opposite directions around a closed loop on an atom chip.Spectroscopy in such potentials is rich in detail [2], and sharp microwave transitions can be used to prepare…

Contributed Talk: Bow-tie two-photon recoil interactions and gray molasses in a ring cavity
H. Eneriz1,2, D. S. Naik1, G. Santana-de-Figueiredo1, P. Bouyer1, and A. Bertoldi1 1LP2N, Universit ́e Bordeaux, IOGS, CNRS, Talence, France2Universit ́e Cˆote d’Azur, INPHYNI, Valbonne, France In our experiment, ultracold 87Rb atoms are charged at the center of the cross–shaped cavity at 1560 nm, where a far off–resonant dipole trap (FORT) is created. High–finesse at 780 nm allows for collective strong atom-cavity coupling via frequency doubling of the 1560 nm source which is locked to the cavity resonance. Cooling of an atomic gas to ultracold temperatures requires a multistage process: laser cooling in a magneto–optical trap (MOT); sub–Doppler cooling; loading into a conservative magnetic or optical trap; and often evaporative…

Contributed Talk: Towards atomic diffraction through single-layer graphene
Christian Brand1 1German Aerospace Center (DLR e.V.), Institute of Quantum Technologies, Wilhelm-Runge-Straße 10, 89081 Ulm, Germany We discuss the prospect of diffracting fast atomic matter waves through atomically thin mem-branes, such as graphene [1]. Using hydrogen atoms with a velocity of up to 120 000 m/s, we predict a high probability of coherently diffracting atoms through the natural lattice of the crystalline gratings. Nevertheless, the minimum distance between the matter wave and the grating is on the picometer scale, leading to significant couplings. As this interplay is encoded in the matter wave, it brings direct and dose-independent imaging of the interaction within reach.While investigations below the damage threshold ensure virtually…

Invited Talk: Matter-Waves lensing in Dynamic Wave-Guides
We have recently demonstrated smooth and controllable matter-wave guides by transporting Bose-Einstein condensates (BECs) over macroscopic distances without any heating or decohering their internal quantum states [9]. A neutral-atom accelerator ring was utilized to bring BECs to very high speeds (up to 16 times their sound velocity) and transport them in a magnetic matter-wave guide for 15 centimetres whilst fully preserving their internal coherence. We then use a magnetogravitational matter-wave lens to collimate and focus matterwaves in ring-shaped time-averaged adiabatic potentials. This “Delta-kick cooling” sequence of Bose-Einstein condensates reduces their expansion energies by a factor of 46 down to 800 pK. Compared to the state-of-the-art experiments, requiring zero gravity or large…
