Topological Semimetals
Speaker(s): Anton Burkov
Abstract: I will describe our recent work on a new topological phase of matter: topological Weyl semimetal. This phase arises in three-dimensional (3D) materials, which are close to a critical point between an ordinary and a topological insulator. Breaking time-reversal symmetry in such materials, for example... read more

Fractional Quantum Hall Effect and Featureless Mott Insulators
Speaker(s): Anton Burkov
Abstract: We point out and explicitly demonstrate a close connection that exists between featureless Mott insulators and fractional quantum Hall liquids. Using magnetic Wannier states as the single-particle basis in the lowest Landau level (LLL), we demonstrate that the Hamiltonian of interacting bosons in th... read more

Stability of Superflow in Ultracold Fermions in Optical Lattices
Speaker(s): Anton Burkov
Abstract: Motivated by recent observations of superfluidity of ultracold fermions in optical lattices, we investigate the stability of superfluid flow of paired fermions in the lowest band of a strong optical lattice. For fillings close to one fermion per site, we show that superflow breaks down via a dynamic... read more
