Phase diagrams of lattice gauge theories with Higgs fields
- E. Fradkin, S. Shenker
- Physics
- 15 June 1979
We study the phase diagram of lattice gauge theories coupled to fixed-length scalar (Higgs) fields. We consider several gauge groups: Z/sub 2/, U(1), and SU(N). We find that when the Higgs fields…

The entanglement entropy of a pure quantum state of a bipartite system A union or logical sumB is defined as the von Neumann entropy of the reduced density matrix obtained by tracing over one of the…
Topological Entanglement Entropy in Chern-Simons Theories and Quantum Hall Fluids

We compute directly the entanglement entropy of spatial regions in Chern-Simons gauge theories in 2+1 dimensions using surgery. We use these results to determine the universal topological piece of…
Nematic Fermi Fluids in Condensed Matter Physics

Correlated electron fluids can exhibit a startling array of complex phases, among which one of the more surprising is the electron nematic, a translationally invariant metallic phase with a…
How to detect fluctuating stripes in the high-temperature superconductors
- S. Kivelson, I. P. Bindloss, C. Howald
- Physics
- 8 October 2003
We discuss fluctuating order in a quantum disordered phase proximate to a quantum critical point, with particular emphasis on fluctuating stripe order. Optimal strategies for extracting information…
Order and disorder in gauge systems and magnets
- E. Fradkin, L. Susskind
- Physics
- 15 May 1978
We show how phase transitions in Abelian two-dimensional spin and four-dimensional gauge systems can be understood in terms of condensation of topological objects. In the spin systems these objects…
Quantum theory of a nematic Fermi fluid
- V. Oganesyan, S. Kivelson, E. Fradkin
- Physics
- 6 February 2001
We develop a microscopic theory of the electronic nematic phase proximate to an isotropic Fermi liquid in both two and three dimensions. Explicit expressions are obtained for the small amplitude…
