Phase diagram of an extended parafermion chain

J Wouters, F Hassler, H Katsura, D Schuricht - SciPost Physics Core, 2022 - scipost.org
We study the phase diagram of an extended parafermion chain, which, in addition to terms
coupling parafermions on neighbouring sites, also possesses terms involving four sites. Via …

Exact dimer phase with anisotropic interaction for one dimensional magnets

HZ Xu, SY Zhang, GC Guo, M Gong - Scientific Reports, 2021 - nature.com
We report the exact dimer phase, in which the ground states are described by product of
singlet dimer, in the extended XYZ model by generalizing the isotropic Majumdar–Ghosh …

Self-dual -invariant quantum chains

E O'Brien, P Fendley - SciPost Physics, 2020 - scipost.org
We investigate the self-dual three-state quantum chain with nearest-neighbor interactions
and $ S_3 $, time-reversal, and parity symmetries. We find a rich phase diagram including …

An exact local map** from clock-spins to fermions

S Traverso, C Fleckenstein, M Sassetti… - SciPost Physics …, 2023 - scipost.org
Clock-spin models are attracting great interest, due to both their rich phase diagram and
their connection to parafermions. In this context, we derive an exact local map** from …

Emergent Haldane phase in an alternating-bond parafermion chain

SY Zhang, HZ Xu, YX Huang, GC Guo, ZW Zhou… - Physical Review B, 2019 - APS
The Haldane phase represents one of the most important symmetry-protected states in
modern physics. This state can be realized using spin-1 and spin-1 2 Heisenberg models …
