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…
Fractality-induced Topology
L. Eek, Z. F. Osseweijer, C. Morais Smith
Fractal geometries, characterized by self-similar patterns and non-integer dimensions, provide an intriguing platform for exploring topological phases of matter. In this work, we i…
Topological phases of the interacting Su-Schrieffer-Heeger model: An analytical study
E. Di Salvo, A. Moustaj, C. Xu +4
The interacting SSH model provides an ideal ground to study the interplay between topologically insulating phases and electron-electron interactions. We study the polarization dens…
Topological edge and corner states in Bi fractals on InSb
R. Canyellas, Chen Liu, R. Arouca +10
Topological materials hosting metallic edges characterized by integer quantized conductivity in an insulating bulk have revolutionized our understanding of transport in matter. The…
Non-Hermitian quantum gases: a platform for imaginary time crystals
R. Arouca, E. C. Marino, C. Morais Smith
One of the most important applications of quantum mechanics is the thermodynamic description of quantum gases. Despite the fundamental importance of this topic, a comprehensive des…
