Coupling approach for the realization of a -symmetric potential for a Bose-Einstein condensate in a double well
Fabian Single, Holger Cartarius, Günter Wunner +1
We show how non-Hermitian potentials used to describe probability gain and loss in effective theories of open quantum systems can be achieved by a coupling of the system to an envi…
Realizing PT-symmetric non-Hermiticity with ultra-cold atoms and Hermitian multi-well potentials
Manuel Kreibich, Jörg Main, Holger Cartarius +1
We discuss the possibility of realizing a non-Hermitian, i.e. an open two-well system of ultra-cold atoms by enclosing it with additional time-dependent wells that serve as particl…
Dipolar Bose-Einstein condensates in a PT-symmetric double-well potential
Rüdiger Fortanier, Dennis Dast, Daniel Haag +4
We investigate dipolar Bose-Einstein condensates in a complex external double-well potential that features a combined parity and time-reversal symmetry. On the basis of the Gross-P…
