Coupled-wire constructions: a Luttinger liquid approach to topology

T Meng - The European Physical Journal Special Topics, 2020 - Springer
Coupled-wire constructions use bosonization to analytically tackle the strong interactions
underlying fractional topological states of matter. We give an introduction to this technique …

Fractional topological superconductivity and parafermion corner states

K Laubscher, D Loss, J Klinovaja - Physical Review Research, 2019 - APS
We consider a system of weakly coupled Rashba nanowires in the strong spin-orbit
interaction (SOI) regime. The nanowires are arranged into two tunnel-coupled layers …

Emerging topological bound states in Haldane model zigzag nanoribbons

S Traverso, M Sassetti, N Traverso Ziani - npj Quantum Materials, 2024 - nature.com
Zigzag nanoribbons hosting the Haldane Chern insulator model are considered. In this
context, a reentrant topological phase, characterized by the emergence of quasi zero …

Dissipative quantum Ising chain as a non-Hermitian Ashkin-Teller model

N Shibata, H Katsura - Physical Review B, 2019 - APS
We study a quantum Ising chain with tailored bulk dissipation, which can be mapped onto a
non-Hermitian Ashkin-Teller model. By exploiting the Kohmoto-den Nijs-Kadanoff …

parafermions in Weakly Interacting Superconducting Constrictions at the Helical Edge of Quantum Spin Hall Insulators

C Fleckenstein, NT Ziani, B Trauzettel - Physical Review Letters, 2019 - APS
Parafermions are generalizations of Majorana fermions that may appear in interacting
topological systems. They are known to be powerful building blocks of topological quantum …

Fermionized parafermions and symmetry-enriched Majorana modes

A Chew, DF Mross, J Alicea - Physical Review B, 2018 - APS
Parafermion zero modes are generalizations of Majorana modes that underlie comparatively
rich non-Abelian-anyon properties. We introduce exact map**s that connect parafermion …

Two-fluid coexistence and phase separation in a one-dimensional model with pair hop** and density interactions

L Gotta, L Mazza, P Simon, G Roux - Physical Review B, 2021 - APS
We compute the phase diagram of a one-dimensional model of spinless fermions with pair
hop** and nearest-neighbor interaction, first introduced by Ruhman and Altman, using the …

Readout of parafermionic states by transport measurements

IE Nielsen, K Flensberg, R Egger, M Burrello - Physical Review Letters, 2022 - APS
Recent experiments have demonstrated the possibility of inducing superconducting pairing
into counterpropagating fractional quantum Hall edge modes. This paves the way for the …

Pretopological fractional excitations in the two-leg flux ladder

M Calvanese Strinati, S Sahoo, K Shtengel, E Sela - Physical Review B, 2019 - APS
Topological order, the hallmark of fractional quantum Hall states, is primarily defined in
terms of ground-state degeneracy on higher-genus manifolds, eg, the torus. We investigate …

Anyonic tight-binding models of parafermions and of fractionalized fermions

D Rossini, M Carrega, M Calvanese Strinati, L Mazza - Physical Review B, 2019 - APS
Parafermions are emergent quasiparticles which generalize Majorana fermions and
possess intriguing anyonic properties. The theoretical investigation of effective models …
