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…

Optical-parametric-oscillator solitons driven by the third harmonic
Vitaly Lutsky, Boris A. Malomed
We introduce a model of a lossy second-harmonic-generating (chi^2) cavity externally pumped at the third harmonic, which gives rise to driving terms of a new type, corresponding to…
