Evolution from Kitaev to XXZ spin chains via distortion: Application to BaCoVO
Philip Richard, Mandev Bhullar, Hae-Young Kee
BaCoVO is a prototypical spin-orbit-coupled Ising-chain antiferromagnet that provides a unique platform for studying field-induced quantum magnetism. Under a transverse…

Microscopic Theory Revealing Ising Criticality with Distinct Sublattice Orders in Pseudospin-1/2 Chain
Mandev Bhullar, Philip Richard, Hae-Young Kee
The one-dimensional transverse Ising model is a paradigmatic example of quantum criticality. In spin-orbit coupled systems, however, effective Ising interactions arise alongside bo…

Disorder induced topological phase transition in a driven Majorana chain
Henry Ling, Philip Richard, Saeed Rahmanian Koshkaki +4
We study a periodically driven one dimensional Kitaev model in the presence of disorder. In the clean limit our model exhibits four topological phases corresponding to the existenc…
