Negative quench induced excitation dynamics for ultracold bosons in one-dimensional lattices
S. I. Mistakidis, L. Cao, P. Schmelcher
The nonequilibrium dynamics following a quench of strongly repulsive bosonic ensembles in one-dimensional finite lattices is investigated by employing interaction quenches and/or a…
Magnetic Quantum Phases of Ultracold Dipolar Gases in an Optical Superlattice
Xiangguo Yin, Lushuai Cao, Peter Schmelcher
We propose an effective Ising spin chain constructed with dipolar quantum gases confined in a one-dimensional optical superlattice. Mapping the motional degrees of freedom of a sin…
Stability and Tunneling Dynamics of a Dark-Bright Soliton Pair in a Harmonic Trap
E. T. Karamatskos, J. Stockhofe, P. G. Kevrekidis +1
We consider a binary repulsive Bose-Einstein condensate in a harmonic trap in one spatial dimension and investigate particular solutions consisting of two dark-bright (DB) solitons…
Bloch dynamics in lattices with long range hoppings
J. Stockhofe, P. Schmelcher
We study a discrete Schrödinger equation with arbitrary long range hopping terms under the influence of an external force. The impact of long range hoppings on the single particle…
Many-body processes in black and grey matter-wave solitons
Sven Krönke, Peter Schmelcher
We perform a comparative beyond mean-field study of black and grey solitonic excitations in a finite ensemble of ultracold bosons confined to a one-dimensional box. An optimized de…
Correlated Quantum Dynamics of a Single Atom Collisionally Coupled to an Ultracold Finite Bosonic Ensemble
Sven Krönke, Johannes Knörzer, Peter Schmelcher
We explore the correlated quantum dynamics of a single atom, regarded as an open system, with a spatio-temporally localized coupling to a finite bosonic environment. The single ato…
