Spin-helix driven insulating phase in two dimensional lattice
Hyun-Jun K. Park, Hyeok-Jun Yang, SungBin Lee
Motivated by emergent symmetry in the spin orbit coupled system, we study the spin helix driven insulating phase in two dimensional lattice. When both Rashba and Dresselhau…

Magnetic field and thermal Hall effect in a pyrochlore U(1) quantum spin liquid
Hyeok-Jun Yang, Hee Seung Kim, SungBin Lee
The antiferromagnetic system on a rare-earth pyrochlore has been focused as a strong candidate of U(1) quantum spin liquid. Here, we study the phase transitions driven by external…

Topological phases of non-symmorphic crystals : Shastry-Sutherland lattice at integer filling
Hyeok-Jun Yang, SungBin Lee
Motivated by intertwined crystal symmetries and topological phases, we study the possible realization of topological insulator in nonsymmorphic crystals at integer fillings. In par…
