Breathers in PT-symmetric optical couplers
I. V. Barashenkov, Sergey V. Suchkov, Andrey A. Sukhorukov +2
We show that the parity-time (PT) symmetric coupled optical waveguides with gain and loss support localised oscillatory structures similar to the breathers of the classical m…

Kink ratchets in the Klein-Gordon lattice free of the Peierls-Nabarro potential
Sergey V. Dmitriev, Avinash Khare, Sergey V. Suchkov
A discrete Klein-Gordon model with asymmetric potential that supports kinks free of the Peierls-Nabarro potential (PNp) is constructed. Undamped ratchet of kinks under harmonic AC…
