Non-Hermitian propagation in equally-spaced Hermitian waveguide arrays
Ivan Bocanegra, Héctor M. Moya-Cessa
A non-unitary transformation leading to a Hatano-Nelson problem is performed on an array of equally-spaced optical waveguides. Such transformation produces a non-reciprocal system…
Non-Hermitian propagation in Glauber-Fock optical lattices
Ivan Bocanegra, Héctor M. Moya-Cessa
The effect of a non-unitary transformation on an initial Hermitian operator is studied. The initial (Hermitian) optical system is a Glauber-Fock optical lattice. The resulting non-…
Exact solutions to the Telegraph equation in terms of Airy functions
Felipe A. Asenjo, Sergio A. Hojman, Braulio M. Villegas-Martínez +2
Two exact different solutions to the Telegraph equation in three-dimensional space are obtained in terms of Airy functions. As a result, these solutions unveil a distinctive propag…
Supersymmetric behavior of polarized electromagnetic waves in anisotropic media
Felipe A. Asenjo, Sergio A. Hojman, Braulio M. Villegas-Martínez +2
A medium with specific anisotropic refractive indices can induce a supersymmetric behavior in the propagation of polarized electromagnetic waves, in an analogue fashion to a quantu…
Moving mirror-field dynamics under intrinsic decoherence
Alejandro R. Urzúa, Héctor M. Moya-Cessa
We study the decaying dynamics in the mirror-field interaction by means of the intrinsic decoherence scheme. Factorization of the mirror-field Hamiltonian with the use of displacem…
Non-unitary transformation approach to dynamics
Braulio M. Villegas-Martínez, Francisco Soto-Eguibar, Sergio A. Hojman +2
We show that several Hamiltonians that are symmetric may be taken to Hermitian Hamiltonians via a non-unitary transformation and vice versa. We also show that for so…
