Rashba spin-orbit coupling in the square lattice Hubbard model: A truncated-unity functional renormalization group study
Jacob Beyer, Jonas B. Profe, Lennart Klebl +5
The Rashba-Hubbard model on the square lattice is the paradigmatic case for studying the effect of spin-orbit coupling, which breaks spin and inversion symmetry, in a correlated el…
Detrimental effects of disorder in two-dimensional time-reversal invariant topological superconductors
Mahdi Mashkoori, Fariborz Parhizgar, Stephan Rachel +1
The robustness against local perturbations, as long as the symmetry of the system is preserved, is a distinctive feature of topological quantum states. Magnetic impurities and defe…
Increased localization of Majorana modes in antiferromagnetic chains on superconductors
Daniel Crawford, Eric Mascot, Makoto Shimizu +4
Magnet-superconductor hybrid (MSH) systems are a key platform for custom-designed topological superconductors. Ideally, the ends of a one-dimensional MSH structure will host Majora…
Hilbert space fragmentation and interaction-induced localization in the extended Fermi-Hubbard model
Philipp Frey, Lucas Hackl, Stephan Rachel
We study Hilbert space fragmentation in the extended Fermi-Hubbard model with nearest and next-nearest-neighbor interactions. Using a generalized spin/mover picture and saddle poin…
Quasiparticle excitations in a one-dimensional interacting topological insulator: Application for dopant-based quantum simulation
David Mikhail, Benoit Voisin, Dominique Didier St Medar +3
We study the effects of electron-electron interactions on the charge excitation spectrum of the spinful Su-Schrieffer-Heeger (SSH) model, a prototype of a 1D bulk obstructed topolo…
