Variational methods with coupled Gaussian functions for Bose-Einstein condensates with long-range interactions. II. Applications
Stefan Rau, Jörg Main, Holger Cartarius +2
Bose-Einstein condensates with an attractive 1/r interaction and with dipole-dipole interaction are investigated in the framework of the Gaussian variational ansatz introduced by S…
Variational methods with coupled Gaussian functions for Bose-Einstein condensates with long-range interactions. I. General concept
Stefan Rau, Jörg Main, Günter Wunner
The variational method of coupled Gaussian functions is applied to Bose-Einstein condensates with long-range interactions. The time-dependence of the condensate is described by dyn…
Fractal Weyl law for three-dimensional chaotic hard-sphere scattering systems
Alexander Eberspächer, Jörg Main, Günter Wunner
The fractal Weyl law connects the asymptotic level number with the fractal dimension of the chaotic repeller. We provide the first test for the fractal Weyl law for a three-dimensi…
Variational calculations on multilayer stacks of dipolar Bose-Einstein condensates
Andrej Junginger, Jörg Main, Günter Wunner
We investigate a multilayer stack of dipolar Bose-Einstein condensates in terms of a simple Gaussian variational ansatz and demonstrate that this arrangement is characterized by th…
Resonance wave functions located at the Stark saddle point
Holger Cartarius, Jörg Main, Thorsten Losch +1
We calculate quantum mechanically exact wave functions of resonances in spectra of the hydrogen atom in crossed external fields and prove the existence of long-lived decaying quant…
