We investigate the effect of nonlinearity in novel parity-time (PT) symmetric potentials. We show that new types of nonlinear self-trapped modes can exist in optical PT synthetic lattices.
Theory of coupled optical PT-symmetric structures.

Starting from Lagrangian principles we develop a formalism suitable for describing coupled optical parity-time symmetric systems.
Unidirectional nonlinear PT-symmetric optical structures
- H. Ramézani, T. Kottos, +5 authors U. Florida
- Physics
- 27 May 2010
We show that nonlinear optical structures involving a balanced gain-loss profile can act as unidirectional optical valves. This is made possible by exploiting the interplay between the fundamental… Expand

- Physical review letters
- 13 March 2008
The possibility of parity-time (PT) symmetric periodic potentials is investigated within the context of optics. Beam dynamics in this new type of optical structures is examined in detail for both… Expand
Enhanced sensitivity at higher-order exceptional points

- Physics, Medicine
- Nature
- 9 August 2017
Non-Hermitian degeneracies, also known as exceptional points, have recently emerged as a new way to engineer the response of open physical systems, that is, those that interact with the environment.… Expand
Non-Hermitian physics and PT symmetry
- R. El-Ganainy, K. Makris, M. Khajavikhan, Z. Musslimani, S. Rotter, D. Christodoulides
- Physics
- 2018
In recent years, notions drawn from non-Hermitian physics and parity–time (PT) symmetry have attracted considerable attention. In particular, the realization that the interplay between gain and loss… Expand
Analytical solutions to a class of nonlinear Schrödinger equations with {\cal PT} -like potentials
- Z. Musslimani, K. Makris, R. El-Ganainy, D. Christodoulides
- Mathematics
- 3 June 2008
We present closed form solutions to a certain class of one- and two-dimensional nonlinear Schr¨ odinger equations involving potentials with broken and unbroken PT symmetry. In the one-dimensional… Expand
Optical Solitons in PT Periodic Potentials

- Physics
- 4 June 2010
The basic properties of Floquet-Bloch (FB) modes in parity-time (PT)-symmetric optical lattices are examined in detail. Due to the parity-time symmetry of such complex periodic potentials, the… Expand
