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…
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…
Hybrid Breathers in Nonlinear -Symmetric Metamaterials
Sascha Böhrkircher, Sebastian Erfort, Holger Cartarius +1
On a two-dimensional planar parity-time-(-)symmetric nonlinear magnetic metamaterial, consisting of split-ring dimers with balanced gain and loss, discrete breather s…
