Hunting Majorana fermions in Kitaev magnets

Y Motome, J Nasu - Journal of the Physical Society of Japan, 2020 - journals.jps.jp
A Majorana fermion is a fermionic particle that is its own antiparticle. Since the theoretical
discovery by Ettore Majorana in 1937, the exotic particle has long been searched in particle …

Monitored quantum dynamics and the Kitaev spin liquid

Anderson–Kitaev spin liquid

MG Yamada - npj Quantum Materials, 2020 - nature.com
The bond-disordered Kitaev model attracts much attention due to the experimental
relevance in α-RuCl3 and A 3LiIr2O6 (A= H, D, Ag, etc.). Applying a magnetic field to break …

Majorana-magnon crossover by a magnetic field in the Kitaev model: Continuous-time quantum Monte Carlo study

J Yoshitake, J Nasu, Y Kato, Y Motome - Physical Review B, 2020 - APS
Kitaev quantum spin liquids host Majorana fermions via the fractionalization of spins. In a
magnetic field, the Majorana fermions were predicted to comprise a topological state, which …

Subdiffusive dynamics and critical quantum correlations in a disorder-free localized Kitaev honeycomb model out of equilibrium

GY Zhu, M Heyl - Physical Review Research, 2021 - APS
Disorder-free localization has recently emerged as a mechanism for ergodicity breaking in
homogeneous lattice gauge theories. In this work we show that this mechanism can lead to …

Qubit fractionalization and emergent Majorana liquid in the honeycomb Floquet code induced by coherent errors and weak measurements

GY Zhu, S Trebst - arxiv preprint arxiv:2311.08450, 2023 - arxiv.org
