Stability of edge states in strained graphene
Pouyan Ghaemi, Sarang Gopalakrishnan, Shinsei Ryu
Spatially inhomogeneous strains in graphene can simulate the effects of valley-dependent magnetic fields. As demonstrated in recent experiments, the realizable magnetic fields are…
Vortex Lattices in the Superconducting Phases of Doped Topological Insulators and Heterostructures
Hsiang-Hsuan Hung, Pouyan Ghaemi, Taylor L. Hughes +1
Majorana fermions are predicted to play a crucial role in condensed matter realizations of topological quantum computation. These heretofore undiscovered quasiparticles have been p…
Universal transport near a quantum critical Mott transition in two dimensions
William Witczak-Krempa, Pouyan Ghaemi, T. Senthil +1
We discuss the universal transport signatures near a zero-temperature continuous Mott transition between a Fermi liquid (FL) and a quantum spin liquid in two spatial dimensions. Th…
Designer quantum spin Hall phase transition in molecular graphene
Pouyan Ghaemi, Sarang Gopalakrishnan, Taylor L. Hughes
Graphene was the first material predicted to be a time-reversal-invariant topological insulator; however, the insulating gap is immeasurably small owing to the weakness of spin-orb…
Non-Abelian SU(2) gauge fields through density-wave order and strain in graphene
Sarang Gopalakrishnan, Pouyan Ghaemi, Shinsei Ryu
Spatially varying strain patterns can qualitatively alter the electronic properties of graphene, acting as effective valley-dependent magnetic fields and giving rise to pseudo-Land…
Stabilization of Majorana modes in vortices in the superconducting phase of topological insulators using topologically trivial bands
Ching-Kai Chiu, Pouyan Ghaemi, Taylor L. Hughes
If superconductivity is induced in the metallic surface states of topological insulators via proximity, Majorana modes will be trapped on the vortex cores. The same effects hold fo…
