Flux crystals, majorana metals, and flat bands in exactly solvable spin-orbital liquids
Spin-orbital liquids are quantum disordered states in systems with entangled spin and
orbital degrees of freedom. We study exactly solvable spin-orbital models in two dimensions …

Higher-order topological superconductivity in twisted bilayer graphene
We show that introducing spin-singlet or spin-triplet superconductivity into twisted bilayer
graphene induces higher-order topological superconductivity. Multiple copies of C 2 z T …

Bosonization of Majorana modes and edge states
A Bochniak, B Ruba, J Wosiek - Physical Review B, 2022 - APS
We present a bosonization procedure, which replaces fermions with generalized spin
variables subject to local constraints. It requires that the number of Majorana modes per …

Quantum entanglement of XY-type spin dimers in Shastry-Sutherland lattice
We report a comprehensive study on the origin of the enigmatic disordered ground state
within the Shastry-Sutherland lattice, BaCe $ _2 $ ZnS $ _5 $, at low temperatures. The …
