Magnetic effect on the rotational frequency of a neutron star
Manfred Faehnle, Guenter Wunner
A neutron star contains regions with particles which exhibit magnetic moments, which, in turn, generate respective magnetizations. By magnetoelastic interactions between the magnet…
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 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…
Pitchfork bifurcations in blood-cell shaped dipolar Bose-Einstein condensates
Stefan Rau, Jörg Main, Patrick Köberle +1
We demonstrate that the method of coupled Gaussian wave packets is a full-fledged alternative to direct numerical solutions of the Gross-Pitaevskii equation of condensates with ele…
Discovery of exceptional points in the Bose-Einstein condensation of gases with attractive 1/r-interaction
Holger Cartarius, Jörg Main, Günter Wunner
The extended Gross-Pitaevskii equation for the Bose-Einstein condensation of gases with attractive 1/r-interaction has a second solution which is born together with the ground stat…
