Analytical description of collisional decoherence in a BEC double-well accelerometer
Kateryna Korshynska, Sebastian Ulbricht
BEC-based quantum sensors offer a huge, yet not fully explored potential in gravimetry and ac- celerometry. In this paper, we study a possible setup for such a device, which is a w…

Generalized Josephson effect in an asymmetric double-well potential at finite temperatures
Kateryna Korshynska, Sebastian Ulbricht
We investigate a non-interacting many-particle bosonic system, placed in an asymmetric double-well potential. We first consider the dynamics of a single particle and determine its…
