Exceptional Points revealed by the integrated imaginary scattering eigenphase
J. Colín-Gálvez, V. Domínguez-Rocha, J. E. Toral-Zavaleta
We propose and analytically demonstrate that the eigenphases of the scattering matrix provide direct, phase-sensitive signatures of EPs in open PT-symmetric systems. Using a 1D PT-…
The rise and fall of the amplitude, and phase, around Exceptional Points: a Scattering matrix approach
J. Colín-Gálvez, E. Castaño, G. Báez +1
We analyze the behavior of a non-Hermitian opened one-dimensional quantum system with symmetry. This system is built by a dimer, with balanced gains and losses descr…
Environmentally-induced exceptional points in elastodynamics
V. Dominguez-Rocha, Ramathasan Thevamaran, F. M. Ellis +1
We study the nature of an environment-induced exceptional point in a non-Hermitian pair of coupled mechanical oscillators. The mechanical oscillators are a pair of pillars carved o…
Typical length scales in conducting disorderless networks
M. Martínez-Mares, V. Domínguez-Rocha, A. Robledo
We take advantage of a recently established equivalence, between the intermittent dynamics of a deterministic nonlinear map and the scattering matrix properties of a disorderless d…
Evolution with size in a locally periodic system: Scattering and deterministic maps
V. Dominguez-Rocha, M. Martinez-Mares
In this paper we study the evolution of the wave function with the system size in a locally periodic structure. In particular we analyse the dependence of the wave function with th…
Poynting's theorem for planes waves at an interface: a scattering matrix approach
V. Dominguez-Rocha, C. Zagoya, M. Martinez-Mares
We apply the Poynting theorem to the scattering of monochromatic electromagnetic planes waves with normal incidence to the interface of two different media. We write this energy co…
