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 …

Magnetic crystals and helical liquids in alkaline-earth fermionic gases

S Barbarino, L Taddia, D Rossini, L Mazza… - Nature …, 2015 - nature.com
The joint action of a magnetic field and of interactions is crucial for the appearance of exotic
quantum phenomena, such as the quantum Hall effect. Owing to their rich nuclear structure …

Phase diagram of the parafermionic chain with chiral interactions

Y Zhuang, HJ Changlani, NM Tubman, TL Hughes - Physical Review B, 2015 - APS
Parafermions are exotic quasiparticles with non-Abelian fractional statistics that can be
realized and stabilized in one-dimensional models that are generalizations of the Kitaev p …

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 …

Interrelations among frustration-free models via Witten's conjugation

J Wouters, H Katsura, D Schuricht - SciPost Physics Core, 2021 - scipost.org
We apply Witten's conjugation argument [Nucl. Phys. B 202, 253 (1982)] to spin chains,
where it allows us to derive frustration-free systems and their exact ground states from …

Phase transitions in the and U(1) clock models

G Sun, T Vekua, E Cobanera, G Ortiz - Physical Review B, 2019 - APS
Quantum phase transitions are studied in the nonchiral p-clock chain, and a new explicitly U
(1)-symmetric clock model, by monitoring the ground-state fidelity susceptibility. For p≥ 5 …

Dynamics of parafermionic states in transport measurements

IE Nielsen, J Schulenborg, R Egger, M Burrello - SciPost Physics, 2023 - scipost.org

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

F Iemini, C Mora, L Mazza - Physical Review Letters, 2017 - APS

realize topological order. In this Letter, we present a nontrivial and quasi-exactly-solvable …

Parafermion chain with Floquet edge modes

GJ Sreejith, A Lazarides, R Moessner - Physical Review B, 2016 - APS
We study parafermion chains with Z k symmetry subject to a periodic binary drive, focusing
on the case k= 3. We find that the chains support different Floquet edge modes at nontrivial …
