Dynamics and stability of Bose-Einstein condensates with attractive 1/r interaction
Holger Cartarius, Tomaž Fabčič, Jörg Main +1
The time-dependent extended Gross-Pitaevskii equation for Bose-Einstein condensates with attractive 1/r interaction is investigated with both a variational approach and numerically…
Time propagation of constrained coupled Gaussian wave packets
T. Fabcic, J. Main, G. Wunner
The dynamics of quantum systems can be approximated by the time propagation of Gaussian wave packets. Applying a time dependent variational principle, the time evolution of the par…
Exceptional Points in Atomic Spectra
Holger Cartarius, Jörg Main, Günter Wunner
We report the existence of exceptional points for the hydrogen atom in crossed magnetic and electric fields in numerical calculations. The resonances of the system are investigated…
Periodic Orbit Quantization: How to Make Semiclassical Trace Formulae Convergent
J. Main, G. Wunner
Periodic orbit quantization requires an analytic continuation of non-convergent semiclassical trace formulae. We propose two different methods for semiclassical quantization. The f…
