Itinerant magnetism in the triangular lattice Hubbard model at half-doping: Application to twisted transition-metal dichalcogenides
Yuchi He, Roman Rausch, Matthias Peschke +4
We use unrestricted Hartree-Fock, density matrix renormalization group, and variational projected entangled pair state calculations to investigate the ground state phase diagram of…
Charge pumps, boundary modes, and the necessity of unnecessary criticality
Abhishodh Prakash, S. A. Parameswaran
We link the presence of "unnecessary" quantum critical surfaces within a single gapped phase of matter to the non-trivial topology of families of gapped Hamiltonians that encircle…
Majorana edge reconstruction and the non-Abelian thermal Hall puzzle
Tevž LotriÄ, Taige Wang, Michael P. Zaletel +2
Pioneering thermal transport measurements on two-dimensional electron gases in high magnetic fields have demonstrated that the quantized Hall state at filling factor has a…
Fractional Chern Insulators and Competing States in a Twisted MoTe Lattice Model
Yuchi He, S. H. Simon, S. A. Parameswaran
We construct an interacting lattice model for twisted bilayers at a twist angle of approximately 3.7\degree. We use the infinite density matrix renormalization…
