Thermodynamics of analogue black holes in a non-Hermitian tight-binding model
D. F. Munoz-Arboleda, M. Stålhammar, C. Morais Smith
We present a non-Hermitian model with gain/loss and non-reciprocal next-nearest-neighbor hopping that emulates black-hole physics. The model describes a one-dimensional lattice wit…

Emergence of Imaginary Time Crystals in the non-Hermitian Su-Schrieffer-Heeger model
E. Slootman, L. Eek, C. Morais Smith +1
Parity-time symmetry constrains the spectrum of non-Hermitian systems to be either real or come in complex conjugate pairs. The transition between a symmetry-preserving phase with…
