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…

Field-Induced Ordered Phases in Anisotropic Spin-1/2 Kitaev Chains
Mandev Bhullar, Haoting Xu, Hae-Young Kee
Motivated by intense research on two-dimensional spin-1/2 Kitaev materials, Kitaev spin chains and ladders, though geometrically limited, have been studied for their numerical simp…
