Valley magnetism, nematicity, and density wave orders in twisted bilayer graphene
Dmitry V. Chichinadze, Laura Classen, Andrey V. Chubukov
We analyze density-wave and Pomeranchuk orders in twisted bilayer graphene. This compliments our earlier analysis of the pairing instabilities. We assume that near half-filling of…
Competing orders at higher-order Van Hove points
Laura Classen, Andrey V. Chubukov, Carsten Honerkamp +1
Van Hove points are special points in the energy dispersion, where the density of states exhibits analytic singularities. When a Van Hove point is close to the Fermi level, tendenc…
Nematic superconductivity in twisted bilayer graphene
Dmitry V. Chichinadze, Laura Classen, Andrey V. Chubukov
Twisted bilayer graphene displays insulating and superconducting phases caused by exceptional flattening of its lowest energy bands. Superconductivity with highest appears at…
Signatures of coupling between spin waves and Dirac fermions in YbMnBi
A. Sapkota, L. Classen, M. B. Stone +6
We present inelastic neutron scattering (INS) measurements of magnetic excitations in YbMnBi, which reveal features consistent with a direct coupling of magnetic excitations to…
Competing phases of interacting electrons on triangular lattices in moiré heterostructures
Laura Classen, Carsten Honerkamp, Michael M. Scherer
We study the quantum many-body instabilities of interacting electrons with SU(2)SU(2) symmetry in spin and orbital degrees of freedom on the triangular lattice near van-Hov…
