Unidirectional Nonlinear PT-symmetric Optical Structures
Hamidreza Ramezani, Tsampikos Kottos, Ramy El-Ganainy +1
We show that non-linear optical structures involving a balanced gain-loss profile, can act as unidirectional optical valves. This is made possible by exploiting the interplay betwe…
One Parameter Scaling Theory for Stationary States of Disordered Nonlinear Systems
Joshua D. Bodyfelt, Tsampikos Kottos, Boris Shapiro
We show, using detailed numerical analysis and theoretical arguments, that the normalized participation number of the stationary solutions of disordered nonlinear lattices obeys a…
Quantum anomalies and linear response theory
Itamar Sela, James Aisenberg, Tsampikos Kottos +1
The analysis of diffusive energy spreading in quantized chaotic driven systems, leads to a universal paradigm for the emergence of a quantum anomaly. In the classical approximation…
PT-Symmetric Wave Chaos
Carl T. West, Tsampikos Kottos, Tomaz Prosen
We study a new class of chaotic systems with dynamical localization, where gain or loss mechanisms break the Hermiticity, while allowing for parity-time (PT) symmetry. For a value…
