Bypassing the bandwidth theorem with PT symmetry
Hamidreza Ramezani, J. Schindler, F. M. Ellis +2
The beat time τ_{fpt} associated with the energy transfer between two coupled oscillators is dictated by the bandwidth theorem which sets a lower bound τ_{fpt}\sim 1/δω. We show, b…

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…
