Atomtronics is the emerging technology of building circuits where the current is a flow of ultracold atoms propagating as coherent matter waves inside suitable waveguides.\u00a0 In this talk I will describe our atomtronic technology in which the waveguides are created with laser light via the optical dipole potential, and then discuss two quantum sensors based on it.\u00a0 First, we have demonstrated the atomtronic analogue of the dc SQUID and shown that it exhibits the quantum interference that gives the Superconducting Quantum Interference Device its name.\u00a0\u00a0 In the conventional SQUID this is seen as a periodic variation of critical current with magnetic flux.\u00a0 In the atomtronic SQUID it causes a periodic variation of critical current with rotation, enabling the device to function as a gyro.\u00a0 Second, we are developing an atomtronic version of the Fiber Optic Gyro, in which rotation is measured by the Sagnac effect.\u00a0 In our device a Bose-Einstein condensate is split, reflected, and recombined inside a waveguide that is translated so that the wavepackets travel around a loop and realize a waveguide Sagnac atom interferometer.<\/p>\n","protected":false},"excerpt":{"rendered":"
