Dynamics and symmetries of a repulsively bound atom pair in an infinite optical lattice
Andreas Deuchert, Kaspar Sakmann, Alexej I. Streltsov +2
We investigate the dynamics of two bosons trapped in an infinite one-dimensional optical lattice potential within the framework of the Bose-Hubbard model and derive an exact expres…

Mechanism of Tunneling in Interacting Open Ultracold Few-Boson Systems
Axel U. J. Lode, Alexej I. Streltsov, Ofir E. Alon +1
We investigate the mechanism in the tunneling dynamics of open ultracold few-boson systems by numerically solving the time-dependent few-boson Schrödinger equation exactly. By star…
