Composite fermionization of 1-D Bose-Bose mixtures
Sascha Zöllner, Hans-Dieter Meyer, Peter Schmelcher
We study the ground states of one-dimensional Bose-Bose mixtures under harmonic confinement. As we vary the inter-species coupling strength up to the limit of infinite repulsion, w…
Tunneling dynamics of few bosons in a double well
Sascha Zöllner, Hans-Dieter Meyer, Peter Schmelcher
We study few-boson tunneling in a one-dimensional double well. As we pass from weak interactions to the fermionization limit, the Rabi oscillations first give way to highly delayed…
Quantum dynamics of two bosons in an anharmonic trap: Collective vs internal excitations
Christian Matthies, Sascha Zöllner, Hans-Dieter Meyer +1
This work deals with the effects of an anharmonic trap on an interacting two-boson system in one dimension. Our primary focus is on the role of the induced coupling between the cen…
Excitations of Few-Boson Systems in 1-D Harmonic and Double Wells
Sascha Zöllner, Hans-Dieter Meyer, Peter Schmelcher
We examine the lowest excitations of one-dimensional few-boson systems trapped in double wells of variable barrier height. Based on a numerically exact multi-configurational method…
Correlations in Ultracold Trapped Few-Boson Systems: Transition from Condensation to Fermionization
Sascha Zöllner, Hans-Dieter Meyer, Peter Schmelcher
We study the correlation properties of the ground states of few ultracold bosons, trapped in double wells of varying barrier height in one dimension. Extending previous results on…
Ultracold Few-Boson Systems in a Double-Well Trap
Sascha Zöllner, Hans-Dieter Meyer, Peter Schmelcher
We investigate the transition of a quasi-one-dimensional few-boson system from a weakly correlated to a fragmented and finally a fermionized ground state. Our numerically exact ana…
