Topological phases with parafermions: theory and blueprints

J Alicea, P Fendley - Annual Review of Condensed Matter …, 2016 - annualreviews.org
We concisely review the recent evolution in the study of parafermions—exotic emergent
excitations that generalize Majorana fermions and similarly underpin a host of novel …

Strong zero modes and eigenstate phase transitions in the XYZ/interacting Majorana chain

P Fendley - Journal of Physics A: Mathematical and Theoretical, 2016 - iopscience.iop.org
I explicitly construct a strong zero mode in the XYZ chain or, equivalently, Majorana wires
coupled via a four-fermion interaction. The strong zero mode is an operator that pairs states …

Topological protection of Majorana polaritons in a cavity

Z Bacciconi, GM Andolina, C Mora - Physical Review B, 2024 - APS
Cavity embedding is an emerging paradigm for the control of quantum matter, offering
avenues to manipulate electronic states and potentially drive topological phase transitions …

Disorder operators and their descendants

E Fradkin - Journal of Statistical Physics, 2017 - Springer
I review the concept of a disorder operator, introduced originally by Kadanoff in the context
of the two-dimensional Ising model. Disorder operators acquire an expectation value in the …

Topological and quantum critical properties of the interacting Majorana chain model

N Chepiga, N Laflorencie - SciPost Physics, 2023 - scipost.org
We study Majorana chain with the shortest possible interaction term and in the presence of
hop** alternation. When formulated in terms of spins the model corresponds to the …

Parafermionization, bosonization, and critical parafermionic theories

Y Yao, A Furusaki - Journal of High Energy Physics, 2021 - Springer
A bstract We formulate a ℤ k-parafermionization/bosonization scheme for one-dimensional
lattice models and field theories on a torus, starting from a generalized Jordan-Wigner …

Exact zero modes in twisted Kitaev chains

K Kawabata, R Kobayashi, N Wu, H Katsura - Physical Review B, 2017 - APS
We study the Kitaev chain under generalized twisted boundary conditions, for which both the
amplitudes and the phases of the boundary couplings can be tuned at will. We explicitly …

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 …

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 …

Topological phases of parafermions: A model with exactly solvable ground states

F Iemini, C Mora, L Mazza - Physical Review Letters, 2017 - APS
Parafermions are emergent excitations that generalize Majorana fermions and can also
realize topological order. In this Letter, we present a nontrivial and quasi-exactly-solvable …
