Designer Topological Insulators in Superlattices
Xiao Li, Fan Zhang, Qian Niu +1
Gapless Dirac surface states are protected at the interface of topological and normal band insulators. In a binary superlattice bearing such interfaces, we establish that valley-de…
Anomalous Topological Pumps and Fractional Josephson Effects
Fan Zhang, C. L. Kane
We discover novel topological pumps in the Josephson effects for superconductors. The phase difference, which is odd under the chiral symmetry defined by the product of time-revers…
Zeeman Field-Tuned Transitions for Surface Chern Insulators
Fan Zhang, Xiao Li, Ji Feng +2
Mirror symmetric surfaces of a topological crystalline insulator host even number of Dirac surface states. A surface Zeeman field generically gaps these states leading to a quantiz…
Magnetic control of the valley degree of freedom of massive Dirac fermions with application to transition metal dichalcogenides
Tianyi Cai, Shengyuan A. Yang, Xiao Li +4
We study the valley-dependent magnetic and transport properties of massive Dirac fermions in multivalley systems such as the transition metal dichalcogenides. The asymmetry of the…
Topological Mirror Superconductivity
Fan Zhang, C. L. Kane, E. J. Mele
We demonstrate the existence of topological superconductors (SC) protected by mirror and time reversal (TR) symmetries. D-dimensional (D=1,2,3) crystalline SCs are characterized by…
Transport studies of dual-gated ABC and ABA trilayer graphene: band gap opening and band structure tuning in very large perpendicular electric field
K. Zou, Fan Zhang, C. Clapp +2
We report on the transport properties of ABC and ABA stacked trilayer graphene using dual, locally gated field effect devices. The high efficiency and large breakdown voltage of th…
Signatures of Majorana Fermions in Topological Insulator Josephson Junction Devices
Benjamin J. Wieder, Fan Zhang, C. L. Kane
We study theoretically the electrical current and low-frequency noise for a linear Josephson junction structure on a topological insulator, in which the superconductor forms a clos…
Valley Chern Numbers and Boundary Modes in Gapped Bilayer Graphene
Fan Zhang, A. H. MacDonald, E. J. Mele
Electronic states at domain walls in bilayer graphene are studied by analyzing their four and two band continuum models, by performing numerical calculations on the lattice, and by…
