Making the PT symmetry unbreakable
Vitaly Lutsky, Eitam Luz, Er'el Granot +1
It is well known that typical PT-symmetric systems suffer symmetry breaking when the strength of the gain-loss terms exceeds a certain critical value. We present a summary of recen…

Solitons supported by singular modulation of the cubic nonlinearity
Vitaly Lutsky, Boris A. Malomed
A model of the optical media with a spatially structured Kerr nonlinearity is introduced. The nonlinearity strength is modulated by a set of singular peaks on top of a self-focusin…

One- and two-dimensional solitons supported by singular modulation of quadratic nonlinearity
Vitaly Lutsky, Boris A. Malomed
We introduce a model of one- and two-dimensional (1D and 2D) optical media with the nonlinearity whose local strength is subject to cusp-shaped spatial modulation, $χ^{(2…
