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… Expand

Entanglement entropy of 2D conformal quantum critical points: hearing the shape of a quantum drum.

- E. Fradkin, Joel E Moore
- Physics, MedicinePhysical review letters
- 29 May 2006

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… Expand

Topological Order and Conformal Quantum Critical Points

- E. Ardonne, P. Fendley, E. Fradkin
- Physics
- 20 November 2003

Abstract We discuss a certain class of two-dimensional quantum systems which exhibit conventional order and topological order, as well as quantum critical points separating these phases. All of the… Expand

How to detect fluctuating stripes in the high-temperature superconductors

- S. Kivelson, I. P. Bindloss, +4 authors 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… Expand

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… Expand

Topological Entanglement Entropy in Chern-Simons Theories and Quantum Hall Fluids

- Shiying Dong, E. Fradkin, R. Leigh, S. Nowling
- Physics
- 21 February 2008

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… Expand

Nematic Fermi Fluids in Condensed Matter Physics

- E. Fradkin, S. Kivelson, M. Lawler, J. Eisenstein, A. Mackenzie
- Physics
- 21 October 2009

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… Expand

Colloquium : Theory of intertwined orders in high temperature superconductors

- E. Fradkin, S. Kivelson, J. Tranquada
- Physics
- 16 July 2014

Understanding high temperature superconductors is a central problem in condensed matter physics. Many experiments have uncovered ordering tendencies which are responsible for the complex phase… Expand
