Topological Semimetals from first-principles
Heng Gao, Jörn W. F. Venderbos, Youngkuk Kim +1
We review recent theoretical progress in the understanding and prediction of novel topological semimetals. Topological semimetals define a class of gapless electronic phases exhibi…
Nematic superconductivity stabilized by density wave fluctuations: Possible application to twisted bilayer graphene
Vladyslav Kozii, Hiroki Isobe, Jörn W. F. Venderbos +1
Nematic superconductors possess unconventional superconducting order parameters that spontaneously break rotational symmetry of the underlying crystal. In this work we propose a me…
Higher angular momentum band inversions in two dimensions
Jörn W. F. Venderbos, Yichen Hu, C. L. Kane
We study a special class of topological phase transitions in two dimensions described by the inversion of bands with relative angular momentum higher than 1. A band inversion of th…
Fractional Excitonic Insulator
Yichen Hu, Jörn W. F. Venderbos, C. L. Kane
We argue that a correlated fluid of electrons and holes can exhibit a fractional quantum Hall effect at zero magnetic field analogous to the Laughlin state at filling . We int…
The Dirac-Weyl semimetal: Coexistence of Dirac and Weyl fermions in polar hexagonal crystals
Heng Gao, Youngkuk Kim, Jörn W. F. Venderbos +4
We propose that the noncentrosymmetric LiGaGe-type hexagonal crystal SrHgPb realizes a new type of topological semimetal that hosts both Dirac and Weyl points in momentum spa…
