Balancing gain and loss in symmetrised multi-well potentials
Daniel Dizdarevic, Holger Cartarius, Jörg Main +1
Balanced gain and loss leads to stationary dynamics in open systems. This occurs naturally in PT-symmetric systems, where the imaginary part of the potential describing gain and lo…
Realization of -symmetric and -symmetry broken states in static optical lattice potentials
Felix Kogel, Sebastian Kotzur, Daniel Dizdarevic +2
R. Labouvie et al. [Phys. Rev. Lett. 116, 235302 (2016)] have described an experiment with a weakly interacting Bose-Einstein condensate trapped in a one-dimensional optical lattic…
Purity oscillations in coupled Bose-Einstein condensates
Jonathan Stysch, Felix Roser, Dennis Dast +2
It is shown that the distinct oscillations of the purity of the single-particle density matrix for many-body open quantum systems with balanced gain and loss reported by Dast et al…
