Magnetisms in -type monolayer gallium chalcogenides (GaSe, GaS)
Sianxin Wu, Xia Dai, Hongyi Yu +3
Magnetisms in -type monolayer GaX (X=S,Se) is investigated by performing density-functional calculations. Due to the large density of states near the valence band edge, these mo…
Axion response in Weyl semimetals
Y. Chen, Si Wu, A. A. Burkov
Weyl semimetal is a new phase of matter that provides the first solid state realization of chiral Weyl fermions. Most of its unique physics is a consequence of chiral anomaly, name…
Graphene: Kinks, Superlattices, Landau levels, and Magnetotransport
Matthew Killi, Si Wu, Arun Paramekanti
We review recent work on superlattices in monolayer and bilayer graphene. We highlight the role of the quasiparticle chirality in generating new Dirac fermion modes with tunable an…
Graphene under spatially varying external potentials: Landau levels, magnetotransport, and topological modes
Si Wu, Matthew Killi, Arun Paramekanti
Superlattices (SLs) in monolayer and bilayer graphene, formed by spatially periodic potential variations, lead to a modified bandstructure with extra finite-energy and zero-energy…
Weyl semimetal with broken time reversal and inversion symmetries
A. A. Zyuzin, Si Wu, A. A. Burkov
Weyl semimetal is a new topological state of matter, characterized by the presence of nondegenerate band-touching nodes, separated in momentum space, in its bandstructure. Here we…
Band structures of bilayer graphene superlattices
Matthew Killi, Si Wu, Arun Paramekanti
We formulate a low energy effective Hamiltonian to study superlattices in bilayer graphene (BLG) using a minimal model which supports quadratic band touching points. We show that a…
