PT-symmetric oligomers: analytical solutions, linear stability, and nonlinear dynamics.
In the present work we focus on the case of (few-site) configurations respecting the parity-time (PT) symmetry, i.e., with a spatially odd gain-loss profile. We examine the case of such "oligomers" with not only two sites, as in earlier works, but also the cases of three and four sites. While in the former case of recent experimental interest the picture of existing stationary solutions and the...
متن کاملAsymmetric wave propagation in nonlinear systems.
A mechanism for asymmetric (nonreciprocal) wave transmission is presented. As a reference system, we consider a layered nonlinear, nonmirror-symmetric model described by the one-dimensional discrete nonlinear Schrödinger equation with spatially varying coefficients embedded in an otherwise linear lattice. We construct a class of exact extended solutions such that waves with the same frequency a...
متن کاملNonlinear Wave Propagation Through Cold Plasma
An exciting and extremely active area of research investigation during the past years has been the study of solitons and the related issue of the construction of solutions to a wide class of nonlinear equations. The concept of solitons has now become umbiquitous in modern nonlinear science and indeed can be found in various branches of physics. In nonlinear wave propagation through continuous m...
متن کاملPlane Wave Propagation Through a Planer Slab
An approximation technique is considered for computing transmission and reflection coefficients for propagation of an elastic pulse through a planar slab of finite width. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is s...
متن کاملPLANE WAVE PROPAGATION THROUGH A PLANER SLAB
An approximation technique is considered for computing transmission and reflection coefficients for plane waves propagating through stratified slabs. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is shown that it depends ...
