Tunable transmission via quantum state evolution in oval quantum dots
D. Buchholz, P. Drouvelis, P. Schmelcher
We explore the quantum transmission through open oval shaped quantum dots. The transmission spectra show periodic resonances and, depending on the geometry parameter, a strong supp…
Matter-wave solitons with a periodic, piecewise-constant nonlinearity
A. S. Rodrigues, P. G. Kevrekidis, Mason A. Porter +3
Motivated by recent proposals of ``collisionally inhomogeneous'' Bose-Einstein condensates (BECs), which have a spatially modulated scattering length, we study the existence and st…
Few-boson dynamics in double wells: From single-atom to correlated-pair tunneling
Sascha Zöllner, Hans-Dieter Meyer, Peter Schmelcher
We investigate few-boson tunneling in a one-dimensional double well, covering the full crossover from weak interactions to the fermionization limit of strong correlations. Based on…
Soliton oscillations in collisionally inhomogeneous attractive Bose-Einstein condensates
P. Niarchou, G. Theocharis, P. G. Kevrekidis +2
We investigate bright matter-wave solitons in the presence of a spatially varying nonlinearity. It is demonstrated that a translation mode is excited due to the spatial inhomogenei…
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…
Scattering Dynamics of Driven Closed Billiards
Florian Lenz, Fotis K. Diakonos, Peter Schmelcher
We investigate the classical scattering dynamics of the driven elliptical billiard. Two fundamental scattering mechanisms are identified and employed to understand the rich behavio…
