Mishra, Charu — Guidance of trapped clock states towards realization of rotation sensor

Trapped and guided Sagnac interferometer have an advantage of achieving large effective area compared to free space Sagnac interferometer, which can increase the sensitivity of the rotation sensor. We are in the process of building such a rotation sensor. Our scheme employs atom chip that produce quadrupole fields in ring geometry and radio frequency chip to dress the atoms in the ring. Taking advantage of opposite signatures of Lande g-factors of clock states of 87Rb atoms, our scheme offers state dependent guidance of two clock states which can rotate in ring quadrupole to realize rotation sensor.
