Alice Sinatra<\/a> is a Professeur at the Universit\u00e9 de la Sorbonne.<\/p>\n\n\n\n

Alice Sinatra’s research interests focus on Bose-Einstein condensates and spin squeezing. Her projects delve into two main aspects of the physics of atomic Bose-Einstein condensates. The first aspect encompasses fundamental properties like phase coherence and finite temperature properties. The second aspect explores the utilization of Bose-Einstein condensates to generate non-trivial states of the atomic field. In the future, such non-classical states may have significant implications in metrology, probing the boundary between the quantum and classical worlds, and advancing quantum information processing.<\/p>\n\n\n\n

Alice Sinatra employs classical field methods to describe a degenerate Bose gas, incorporating thermal and quantum fluctuations. She applies these methods to various problems, such as the nucleation and crystallization of a vortex lattice in a rotating Bose-Einstein condensate, and the temporal spreading of the condensate phase at finite temperature. Collaborating with researchers like Emilia Witkowska and Yvan Castin, Alice Sinatra has demonstrated that the condensate phase spreads ballistically in time at finite temperature, calculating the coefficient of phase spreading using a quantum extension of the classical concept of ergodicity in the system. With collaborators like Hadrien Kurkjian and Yvan Castin, she investigated phase coherence in fermionic pair-condensed systems.<\/p>\n\n\n\n

In her exploration of spin squeezing in Bose-Einstein condensates, Alice Sinatra investigates the role of decoherence resulting from finite temperature and particle losses. She collaborates with experimentalists from groups such as the Atom chip group of Jakob Reichel in Paris and the group led by Philipp Treutlein. Notably, she has contributed to the realization of spin squeezed states in a bimodal condensate.<\/p>\n\n\n\n

Alice Sinatra has also delved into quantum optics, previously collaborating with researchers such as Philippe Grangier and Luigi Lugiato on Quantum Non-Demolition Measurements using cold atoms in an optical cavity, and with Ga\u00ebl Reinaudi, Frank Lalo\u00eb, and others on proposals for long-lived quantum memory using nuclear spins of He3.<\/p>\n\n\n\n

Moreover, Alice Sinatra has contributed to advancements in the medical application of polarized helium-3 for lung imaging using nuclear magnetic resonance. With her collaborators, she has demonstrated novel optical pumping schemes at high magnetic fields, enabling the preparation of highly polarized samples of helium-3 directly at relatively high pressure.<\/p>\n\n\n\n
