Hawking Radiation in non-Hermitian Microscopic Analogues
Diego F. Munoz-Arboleda, Cristiane Morais Smith, Marcus Stålhammar
Non-Hermitian systems have recently emerged as a convenient platform to realize black-hole physics. Here, we propose a microscopic open quantum system, namely a fermionic tight-bin…

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…

Thermodynamics and entanglement entropy of the non-Hermitian SSH model
D. F. Munoz-Arboleda, R. Arouca, C. Morais Smith
Topological phase transitions are found in a variety of systems and were shown to be deeply related with a thermodynamic description through scaling relations. Here, we investigate…
