Separable ellipsoids around multipartite states
Robin Y. Wen, Gilles Parez, Liuke Lyu +2
We show that, in finite dimensions, around any -partite product state , there exists an ellipsoid of separable states centered around $ρ_{\…
Constraining quantum critical dynamics: 2+1D Ising model and beyond
William Witczak-Krempa
Quantum critical (QC) phase transitions generally lead to the absence of quasiparticles. The resulting correlated quantum fluid, when thermally excited, displays rich universal dyn…
Conformal field theories at non-zero temperature: operator product expansions, Monte Carlo, and holography
Emanuel Katz, Subir Sachdev, Erik S. Sorensen +1
We compute the non-zero temperature conductivity of conserved flavor currents in conformal field theories (CFTs) in 2+1 spacetime dimensions. At frequencies much greater than the t…
Interacting Weyl semimetals: characterization via the topological Hamiltonian and its breakdown
William Witczak-Krempa, Michael Knap, Dmitry Abanin
Weyl semimetals (WSMs) constitute a 3D phase with linearly-dispersing Weyl excitations at low energy, which lead to unusual electrodynamic responses and open Fermi arcs on boundari…
Gauge-field fluctuations in 3D topological Mott insulators
William Witczak-Krempa, Ting Pong Choy, Yong Baek Kim
We study the low-energy properties of three-dimensional (3D) topological Mott insulators which can be viewed as strong topological insulators of spinons interacting with a three-di…
