Topological phases and twisting of graphene on a dichalcogenide monolayer
Abdulrhman M. Alsharari, Mahmoud M. Asmar, Sergio E. Ulloa
Depositing monolayer graphene on a transition metal dichalcogenide (TMD) semiconductor substrate has been shown to change the dynamics of the electronic states in graphene, inducin…
Proximity-Induced Superconductivity at Non-Helical Topological Insulator Interfaces
David J. Alspaugh, Mahmoud M. Asmar, Daniel E. Sheehy +1
We study how non-helical spin textures at the boundary between a topological insulator (TI) and a superconductor (SC) affect the proximity-induced superconductivity of the TI inter…
Proximity-induced topological phases in bilayer graphene
Abdulrhman M. Alsharari, Mahmoud M. Asmar, Sergio E. Ulloa
We study the band structure of phases induced by depositing bilayer graphene on a transition metal dichalcogenide monolayer. Tight-binding and low-energy effective Hamiltonian calc…
Topological phases of topological insulator thin films
Mahmoud M. Asmar, Daniel E. Sheehy, Ilya Vekhter
We study the properties of a thin film of topological insulator material. We treat the coupling between helical states at opposite surfaces of the film in the properly-adapted tunn…
