Time Reversal Invariant Topological Superconductivity and Majorana Kramers Pairs
Fan Zhang, C. L. Kane, E. J. Mele
We propose a feasible route to engineer one and two dimensional time reversal invariant (TRI) topological superconductors (SC) via proximity effects between nodeless extended s wav…
Broken Symmetry Quantum Hall States in Dual Gated ABA Trilayer Graphene
Yongjin Lee, Jairo Velasco, David Tran +6
We present low temperature transport measurements on dual-gated suspended trilayer graphene in the quantum Hall (QH) regime. We observe QH plateaus at filling factors ν=-8, -2, 2,…
Surface State Magnetization and Chiral Edge States on Topological Insulators
Fan Zhang, C. L. Kane, E. J. Mele
We study the interaction between a ferromagnetically ordered medium and the surface states of a topological insulator with a general surface termination. This interaction is strong…
Unconventional Quantum Hall Effect and Tunable Spin Hall Effect in MoS2 Trilayers
Xiao Li, Fan Zhang, Qian Niu
We analyze the Landau level (LL) structure and spin Hall effect in a MoS2 trilayer. Due to orbital asymmetry, the low-energy Dirac fermions become heavily massive and the LL energi…
Competing Ordered States in Bilayer Graphene
Fan Zhang, Hongki Min, A. H. MacDonald
We use a perturbative renormalization group approach with short-range continuum model interactions to analyze the competition between isotropic gapped and anisotropic gapless order…
Surface States of Topological Insulators
Fan Zhang, C. L. Kane, E. J. Mele
We develop an effective bulk model with a topological boundary condition to study the surface states of topological insulators. We find that the Dirac point energy, the band curvat…
Minimum Conductivity and Evidence for Phase Transitions in Ultra-clean Bilayer Graphene
Wenzhong Bao, Jairo Velasco, Fan Zhang +6
Bilayer graphene (BLG) at the charge neutrality point (CNP) is strongly susceptible to electronic interactions, and expected to undergo a phase transition into a state with spontan…
Hund's Rules for the N=0 Landau Levels of Trilayer Graphene
Fan Zhang, Dagim Tilahun, Allan H. MacDonald
The N=0 Landau levels of ABC and ABA trilayer graphene both have approximate 12-fold degeneracies that are lifted by interactions to produce strong quantum Hall effects (QHE) at al…
