Quantum Interferometry with Microwave-dressed F=1 Spinor Bose-Einstein Condensates: Role of Initial States and Long Time Evolution
Qimin Zhang, Arne Schwettmann
We numerically investigate atomic interferometry based on spin-exchange collisions in spinor Bose-Einstein condensates in the regime of long evolution times , where…
