Topology and Interactions in a Frustrated Slab: Tuning from Weyl Semimetals to C > 1 Fractional Chern Insulators
E. J. Bergholtz, Zhao Liu, M. Trescher +2
We show that, quite generically, a [111] slab of spin-orbit coupled pyrochlore lattice exhibits surface states whose constant energy curves take the shape of Fermi arcs, localized…
Correlations and entanglement in flat band models with variable Chern numbers
Masafumi Udagawa, Emil J. Bergholtz
We discuss a number of illuminating results for tight binding models supporting a band with variable Chern number, and illustrate them explicitly for a simple class of two-banded m…
Entanglement Spectrum in Cluster Dynamical Mean-Field Theory
Masafumi Udagawa, Yukitoshi Motome
We study the entanglement spectrum of the Hubbard model at half filling on a kagome lattice. The entanglement spectrum is defined by the set of eigenvalues of reduced thermal densi…
Vaporization of Kitaev spin liquids
Joji Nasu, Masafumi Udagawa, Yukitoshi Motome
Quantum spin liquid is an exotic quantum state of matter in magnets. This state is a spin analogue of the liquid helium which does not solidify down to the lowest temperature due t…
