Tilted optical lattices with defects as realizations of PT symmetry in Bose-Einstein condensates
Manuel Kreibich, Jörg Main, Holger Cartarius +1
A PT-symmetric Bose-Einstein condensate can theoretically be described using a complex optical potential, however, the experimental realization of such an optical potential describ…
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…
Hermitian four-well potential as a realization of a PT-symmetric system
Manuel Kreibich, Jörg Main, Holger Cartarius +1
A PT-symmetric Bose-Einstein condensate can be theoretically described using a complex optical potential, however, the experimental realization of such an optical potential describ…
