Low Dimensional Ultra-Cold Atom Interferometers

Recent experiments realized matter wave interferometers by dynamically splitting a low-dimensional condensate into two parallel parts. How long do the decoupled condensates remain in phase? I will show that the dephasing time is determined by intrinsic quantum fluctuations that randomize the relative phase with time. Furthermore, I will elucidate on how these systems can serve as a laboratory for studying many body quantum dynamics far from equilibrium.
