Resonant Combinatorial Frequency Generation Induced by a PT-symmetric Periodic Layered Stack
Oksana V. Shramkova, Giorgos P. Tsironis
The nonlinear interaction of waves in PT-symmetric periodic stacks with an embedded nonlinear anisotropic dielectric layer illuminated by plane waves of two tones is examined. The…

Long-lived discrete breathers in free-standing graphene
Alberto Fraile, Emmanuel N. Koukaras, Konstantinos Papagelis +2
Intrinsic localized modes or discrete breathers are investigated by molecular dynamics simulations in free-standing graphene. Discrete breathers are generated either through therma…
