Topological insulators in twisted transition metal dichalcogenide homobilayers
Fengcheng Wu, Timothy Lovorn, Emanuel Tutuc +2
We show that moiré bands of twisted homobilayers can be topologically nontrivial, and illustrate the tendency by studying valence band states in valleys of twisted bilayer…
Chiral transport and electronic correlations in surface states of HfNiSn single crystals
L. Steinke, J. J. Kistner-Morris, T. F. Lovorn +9
In most topological insulators, the valence and conduction band appear in reverse or inverted order compared to an equivalent insulator with isolated atoms. Here, we explore a diff…
Hubbard model physics in transition metal dichalcogenide moiré bands
Fengcheng Wu, Timothy Lovorn, Emanuel Tutuc +1
Flexible long period moir\' e superlattices form in two-dimensional van der Waals crystals containing layers that differ slightly in lattice constant or orientation. In this Letter…
Topologically Protected Helical States in Minimally Twisted Bilayer Graphene
Shengqiang Huang, Kyounghwan Kim, Dmitry K. Efimkin +6
In minimally twisted bilayer graphene, a moir{é} pattern consisting of AB and BA stacking regions separated by domain walls forms. These domain walls are predicted to support count…
Theory of optical absorption by interlayer excitons in transition metal dichalcogenide heterobilayers
Fengcheng Wu, Timothy Lovorn, A. H. MacDonald
We present a theory of optical absorption by interlayer excitons in a heterobilayer formed from transition metal dichalcogenides. The theory accounts for the presence of small rela…
Spin-charge split pairing in underdoped cuprate superconductors: support from low- specific heat
Sanjoy K. Sarker, Timothy Lovorn
We calculate the specific heat of a weakly interacting dilute system of bosons on a lattice and show that it is consistent with the measured electronic specific heat in the superco…
