Typical Correlation Length of Sequentially Generated Tensor Network States
Daniel Haag, Flavio Baccari, Georgios Styliaris
The complexity of quantum many-body systems is manifested in the vast diversity of their correlations, making it challenging to distinguish the generic from the atypical features.…
PT-symmetric gain and loss in a rotating Bose-Einstein condensate
Daniel Haag, Dennis Dast, Holger Cartarius +1
PT-symmetric quantum mechanics allows finding stationary states in mean-field systems with balanced gain and loss of particles. In this work we apply this method to rotating Bose-E…
Balanced gain and loss in Bose-Einstein condensates without PT symmetry
Philipp Lunt, Daniel Haag, Dennis Dast +2
Balanced gain and loss renders the mean-field description of Bose-Einstein condensates PT symmetric. However, any experimental realization has to deal with unbalancing in the gain…
Stationary states in the many-particle description of Bose-Einstein condensates with balanced gain and loss
Dennis Dast, Daniel Haag, Holger Cartarius +2
Bose-Einstein condensates with balanced gain and loss can support stationary states despite the exchange of particles with the environment. In the mean-field approximation this is…
Bose-Einstein condensates with balanced gain and loss beyond mean-field theory
Dennis Dast, Daniel Haag, Holger Cartarius +2
Most of the work done in the field of Bose-Einstein condensates with balanced gain and loss has been performed in the mean-field approximation using the PT-symmetric Gross-Pitaevsk…
-symmetric currents of a Bose-Einstein condensate in a triple well
Daniel Haag, Dennis Dast, Holger Cartarius +1
We study the case of -symmetric perturbations of Hermitian Hamiltonians with degenerate eigenvalues using the example of a triple-well system. The degeneracy complica…
