Scattering off an oscillating target: Basic mechanisms and their impact on cross sections
I. Brouzos, A. K. Karlis, C. A. Chrysanthakopoulos +4
We investigate classical scattering off a harmonically oscillating target in two spatial dimensions. The shape of the scatterer is assumed to have a boundary which is locally conve…
Dynamical trapping and chaotic scattering of the harmonically driven barrier
Florian R. N. Koch, Florian Lenz, Christoph Petri +2
A detailed analysis of the classical nonlinear dynamics of a single driven square potential barrier with harmonically oscillating position is performed. The system exhibits dynamic…
Impact of Electric Fields on Highly Excited Rovibrational States of Polar Dimers
Rosario Gonzalez-Ferez, Peter Schmelcher
We study the effect of a strong static homogeneous electric field on the highly excited rovibrational levels of the LiCs dimer in its electronic ground state. Our full rovibrationa…
Matter-Wave Solitons in the Presence of Collisional Inhomogeneities: Perturbation theory and the impact of derivative terms
S. Middelkamp, P. G. Kevrekidis, D. J. Frantzeskakis +1
We study the dynamics of bright and dark matter-wave solitons in the presence of a spatially varying nonlinearity. When the spatial variation does not involve zero crossings, a tra…
The granularity of weakly occupied bosonic fields beyond the local density approximation
M. Eckart, R. Walser, W. P. Schleich +2
We examine ground state correlations for repulsive, quasi one-dimensional bosons in a harmonic trap. In particular, we focus on the few particle limit N=2,3,4,..., where exact nume…
Spinor Bose-Einstein condensate flow past an obstacle
A. S. Rodrigues, P. G. Kevrekidis, R. Carretero-González +4
We study the flow of a spinor (F=1) Bose-Einstein condensate in the presence of an obstacle. We consider the cases of ferromagnetic and polar spin-dependent interactions and find t…
