DOI: 10.1038/s41467-017-01474-8
Abstract: A prominent feature of topological insulators (TIs) is the surface states comprising of spin-nondegenerate massless Dirac fermions. Recent technical advances have made it possible to address the surface transport properties of TI thin films by… read more here.

DOI: 10.1103/physrevb.107.205110
Abstract: We study a system of two-dimensional Dirac electrons (as is realized on the surface of a 3D topological insulator) coupled to an array of localized spins. The spins are coupled ferromagnetically to each other, forming… read more here.

DOI: 10.1103/physrevlett.123.207202
Abstract: A wide variety of complex phases in quantum materials are driven by electron-electron interactions, which are enhanced through density of states peaks. A well-known example occurs at van Hove singularities where the Fermi surface undergoes… read more here.
