Verification of exceptional points in the collapse dynamics of Bose-Einstein condensates
Jonas Brinker, Jacob Fuchs, Jörg Main +2
In Bose-Einstein condensates with an attractive contact interaction the stable ground state and an unstable excited state emerge in a tangent bifurcation at a critical value of the…
Macroscopic quantum tunneling of Bose-Einstein condensates with long-range interaction
Kai Marquardt, Pascal Wieland, Rolf Häfner +3
The ground state of Bose-Einstein condensates with attractive particle interaction is metastable. One of the decay mechanisms of the condensate is a collapse by macroscopic quantum…
A nonlinear dynamics approach to Bogoliubov excitations of Bose-Einstein condensates
M. Kreibich, H. Cartarius, J. Main +1
We assume the macroscopic wave function of a Bose-Einstein condensate as a superposition of Gaussian wave packets, with time-dependent complex width parameters, insert it into the…
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…
