Trapping and transmission of matter-wave solitons in a collisionally inhomogeneous environment
G. Theocharis, P. Schmelcher, P. G. Kevrekidis +1
We investigate bright matter-wave solitons in the presence of a spatially varying scattering length. It is demonstrated that, even in the absence of any external trapping potential…
N-Electron Giant Dipole States in Crossed Electric and Magnetic Fields
Sascha Zoellner, Hans-Dieter Meyer, Peter Schmelcher
Multi-electron giant dipole resonances of atoms in crossed electric and magnetic fields are investigated. Stationary configurations corresponding to a highly symmetric arrangement…
Parallel implementation of the recursive Green's function method
P. S. Drouvelis, P. Schmelcher, P. Bastian
A parallel algorithm for the implementation of the recursive Green's function technique, which is extensively applied in the coherent scattering formalism, is developed. The algori…
Multi-electron giant dipole resonances of atoms in crossed electric and magnetic fields
S. Zöllner, H. -D. Meyer, P. Schmelcher
Multi-electron giant dipole resonances of atoms in crossed electric and magnetic fields are investigated. Stationary configurations corresponding to a highly symmetric arrangement…
Matter-wave solitons of collisionally inhomogeneous condensates
G. Theocharis, P. Schmelcher, P. G. Kevrekidis +1
We investigate the dynamics of matter-wave solitons in the presence of a spatially varying atomic scattering length and nonlinearity. The dynamics of bright and dark solitary waves…
Quantum Scattering in Strong Cylindrical Confinement
Ji il Kim, Joerg Schmiedmayer, Peter Schmelcher
A Green's function formalism to analyze the scattering properties in confined geometries is developed. This includes scattering from a central field inside the guide created e.g. b…
