Finite-state automata for exact matrix product operators of tight-binding Hamiltonians: fractals, quasicrystals, trees and hyperbolic lattices
Marta Brzezińska, Jeanne Colbois, Loïc Herviou
Inspired by the recent progress in the simulation of tight-binding Hamiltonians on large lattices using tensor networks, we introduce a systematic matrix product operator (MPO) con…
Fate of the non-Hermitian skin effect in many-body fermionic systems
Faisal Alsallom, Loïc Herviou, Oleg V. Yazyev +1
We revisit the fate of the skin modes in many-body non-Hermitian fermionic systems. Contrary to the single-particle case, the many-body ground state cannot exhibit an exponential l…
Fractional corner charges in spin-orbit coupled crystals
Frank Schindler, Marta Brzezińska, Wladimir A. Benalcazar +5
We study two-dimensional spinful insulating phases of matter that are protected by time-reversal and crystalline symmetries. To characterize these phases we employ the concept of c…
Topology in the Sierpiński-Hofstadter problem
Marta Brzezińska, Ashley M. Cook, Titus Neupert
Using the Sierpiński carpet and gasket, we investigate whether fractal lattices embedded in two-dimensional space can support topological phases when subjected to a homogeneous ext…
Topological phases in Bi/Sb planar and buckled honeycomb monolayers
N. Nouri, M. Bieniek, M. Brzezinska +5
We investigate topological phases in two-dimensional Bi/Sb honeycomb crystals considering planar, buckled, freestanding and deposited on a substrate structures. We use the multi-or…
Topological phase transitions in Chern insulators within three-band models
P. Potasz, B. Jaworowski, M. Kupczyński +3
We investigate topological phase transitions in Chern insulators within three-band models, focusing on the empty band and lowest band populated by spinless fermions. We consider Li…
