Perfect Valley Filter in Topological Domain Wall
Hui Pan, Xin Li, Fan Zhang +1
We propose a realization of perfect valley filters based on the chiral domain-wall channels between a quantum anomalous Hall insulator and a quantum valley Hall insulator. Uniquely…
surface states of SnTe
Yin Shi, Meng Wu, Fan Zhang +1
The characterization and applications of topological insulators depend critically on their protected surface states, which, however, can be obscured by the presence of trivial dang…
Structured Weyl Points in Spin-Orbit Coupled Fermionic Superfluids
Yong Xu, Fan Zhang, Chuanwei Zhang
We demonstrate that a Weyl point, widely examined in 3D Weyl semimetals and superfluids, can develop a pair of non-degenerate gapless spheres. Such a bouquet of two spheres is char…
Buckled honeycomb lattice and unconventional magnetic response
Shengyuan A. Yang, Hui Pan, Fan Zhang
We study the magnetic response of buckled honeycomb-lattice materials. The buckling breaks the sublattice symmetry, enhances the spin-orbit coupling, and allows the tuning of a top…
Critical Behavior of Four-Terminal Conductance of Bilayer Graphene Domain Walls
Benjamin J. Wieder, Fan Zhang, C. L. Kane
Bilayer graphene in a perpendicular electric field can host domain walls between regions of reversed field direction or interlayer stacking. The gapless modes propagating along the…
Spontaneous Layer-Pseudospin Domain Walls in Bilayer Graphene
Xiao Li, Fan Zhang, Qian Niu +1
Bilayer graphene is susceptible to a family of unusual broken symmetry states with spin and valley dependent layer polarization. We report on a microscopic study of the domain wall…
Time-Reversal-Invariant Fractional Josephson Effect
Fan Zhang, C. L. Kane
We study the Josephson junction mediated by the quantum spin Hall edge states and show that electron-electron interactions lead to a dissipationless fractional Josephson effect in…
Distinct Competing Ordered ν=2 States in Bilayer Graphene
J. Velasco, Y. Lee, Fan Zhang +6
Because of its large density-of-states and the 2π Berry phase near its low-energy band-contact points, neutral bilayer graphene (BLG) at zero magnetic field (B) is susceptible to c…
Dirac and Weyl Superconductors in Three Dimensions
Shengyuan A. Yang, Hui Pan, Fan Zhang
We introduce the concept of 3D Dirac (Weyl) superconductors (SC), which have protected bulk four(two)-fold nodal points and surface Andreev arcs at zero energy. We provide a suffic…
