Perspective on topological states of non-Hermitian lattices
(IOP, 2020)
The search of topological states in non-Hermitian systems has gained a strong momentum over the last two years climbing to the level of an emergent research front. In this perspective we give an overview with a focus on ...
PT-symmetry management in oligomer systems

Quantum thermodynamics aspects with a thermal reservoir based on PT -symmetric Hamiltonians
(2021-08-01)
We present results concerning aspects of quantum thermodynamics under the background of non-Hermitian quantum mechanics for the dynamics of a quantum harmonic oscillator. Since a better control over the parameters in quantum ...
Flat bands and PT symmetry in quasi-one-dimensional lattices
(American Physical Society, 2015)
We examine the effect of adding PT-symmetric gain and loss terms to quasi-one-dimensional lattices (ribbons) that possess flat bands. We focus on three representative cases: the Lieb ribbon, the kagome ribbon, and the stub ...

Phase Transition in PT Symmetric Active Plasmonic Systems
(IEEE, 2016)
Surface plasmon polaritons (SPPs) are coherent electromagnetic surface waves trapped on an insulator-conductor interface. The SPPs decay exponentially along the propagation due to conductor losses, restricting the SPPs ...
On the Eigenvalues of some non-Hermitian oscillators
(IOP Publishing, 2013-04)
We consider a class of one-dimensional non-Hermitian oscillators and discuss the relationship between the real eigenvalues of PT-symmetric oscillators and the resonances obtained by different authors. We also show the ...
