Effective field theories for topological insulators by functional bosonization
AtMa Chan, Taylor L. Hughes, Shinsei Ryu +1
Effective field theories that describes the dynamics of a conserved U(1) current in terms of "hydrodynamic" degrees of freedom of topological phases in condensed matter are discuss…

The Renyi Entropy and the Multifractal Spectrum of Systems Near the Localization Transition
Xiao Chen, Benjamin Hsu, Taylor L. Hughes +1
We show that the Rényi entropies of single particle, extended wave functions for disordered systems contain information about the multifractal spectrum. It is shown for moments of…

Dynamical stability of the quantum Lifshitz theory in 2+1 Dimensions
Benjamin Hsu, Eduardo Fradkin
The role of magnetic and electric perturbations to the quantum Lifshitz model in 2+1 dimensions are examined in this paper. The quantum Lifshitz model is an effective field theory…
