Optimal control for generating excited state expansion in ring potential
Open Physics, 2020 We applied an optimal control algorithm to an ultra-cold atomic system for constructing an atomic Sagnac interferometer in a ring trap. We constructed a ring potential on an atom chip by using an RF-dressed potential.
