Effective three-body interactions for bosons in a double-well confinement
Jacek Dobrzyniecki, Xikun Li, Anne E. B. Nielsen +1
When describing the low-energy physics of bosons in a double-well potential with a high barrier between the wells and sufficiently weak atom-atom interactions, one can to a good ap…
Effective two-mode description of a few ultra-cold bosons in a double-well potential
Jacek Dobrzyniecki, Tomasz Sowiński
We present a construction of an improved two-mode model for modeling the dynamics of interacting ultra-cold bosons confined in a one-dimensional double well trap. Unlike in the typ…
Two bosonic quantum walkers in one-dimensional optical lattices
Dariusz Wiater, Tomasz Sowiński, Jakub Zakrzewski
Dynamical properties of two bosonic quantum walkers in a one-dimensional lattice are studied theoretically. Depending on the initial state, interactions, lattice tilting, and latti…
Four fermions in a one-dimensional harmonic trap: Accuracy of a variational-ansatz approach
Daniel Pęcak, Amin S. Dehkharghani, Nikolaj T. Zinner +1
Detailed analysis of the system of four interacting ultra-cold fermions confined in a one-dimensional harmonic trap is performed. The analysis is done in the framework of a simple…
