Nonlinear PT-symmetric plaquettes
Kai Li, P. G. Kevrekidis, Boris A. Malomed +1
We introduce four basic two-dimensional (2D) plaquette configurations with onsite cubic nonlinearities, which may be used as building blocks for 2D PT -symmetric lattices. For each…

PT symmetry and spontaneous symmetry breaking in a microwave billiard
S. Bittner, B. Dietz, U. Guenther +4
We demonstrate the presence of parity-time (PT) symmetry for the non-Hermitian two-state Hamiltonian of a dissipative microwave billiard in the vicinity of an exceptional point (EP…
