Balanced gain and loss in spatially extended non--symmetric multi-well potentials
Sinan Altinisik, Daniel Dizdarevic, Jörg Main
The experimental realization of balanced gain and loss in a quantum system has been a long standing goal in quantum mechanics since the introduction of the concept of $\mathcal{PT}…
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…
Using mixed many-body particle states to generate exact -symmetry in a time-dependent four-well system
Tina Mathea, Dennis Dast, Daniel Dizdarevic +3
Bose-Einstein condensates with balanced gain and loss in a double-well potential have been shown to exhibit PT-symmetric states. As proposed by Kreibich et al [Phys. Rev. A 87, 051…
Realization of balanced gain and loss in a time-dependent four-mode Bose-Hubbard model
Daniel Dizdarevic, Jörg Main, Kirill Alpin +4
A quantum system exhibiting symmetry is a Bose-Einstein condensate in a double-well potential with balanced particle gain and loss, which is described in the mean-fi…
Cusp bifurcation in the eigenvalue spectrum of PT-symmetric Bose-Einstein condensates
Daniel Dizdarevic, Dennis Dast, Daniel Haag +3
A Bose-Einstein condensate in a double-well potential features stationary solutions even for attractive contact interaction as long as the particle number and therefore the interac…
