Topological phases of fermions in one dimension

- L. Fidkowski, A. Kitaev
- Mathematics, Physics
- 24 August 2010

In this paper we show how the classification of topological phases in insulators and superconductors is changed by interactions, in the case of one-dimensional systems. We focus on the… Expand

The black hole singularity in AdS/CFT

- L. Fidkowski, V. Hubeny, M. Kleban, S. Shenker
- Physics
- 17 June 2003

We explore physics behind the horizon in eternal AdS Schwarzschild black holes. In dimension d > 3 , where the curvature grows large near the singularity, we find distinct but subtle signals of this… Expand

Effects of interactions on the topological classification of free fermion systems

- L. Fidkowski, A. Kitaev
- Physics
- 14 April 2009

We describe in detail a counterexample to the topological classification of free fermion systems. We deal with a one-dimensional chain of Majorana fermions with an unusual T symmetry. The topological… Expand

Non-Abelian Topological Order on the Surface of a 3D Topological Superconductor from an Exactly Solved Model

- L. Fidkowski, Xie Chen, A. Vishwanath
- Physics
- 24 May 2013

Three dimensional topological superconductors (TScs) protected by time reversal (T) symmetry are characterized by gapless Majorana cones on their surface. Free fermion phases with this symmetry… Expand

Universal transport signatures of Majorana fermions in superconductor-Luttinger liquid junctions

- L. Fidkowski, J. Alicea, N. Lindner, R. Lutchyn, M. Fisher
- Physics
- 21 March 2012

One of the most promising proposals for engineering topological superconductivity and Majorana fermions employs a spin-orbit coupled nanowire subjected to a magnetic field and proximate to an s-wave… Expand

Symmetry Enforced Non-Abelian Topological Order at the Surface of a Topological Insulator

- Xie Chen, L. Fidkowski, A. Vishwanath
- Physics
- 13 June 2013

The surfaces of three dimensional topological insulators (3D TIs) are generally described as Dirac metals, with a single Dirac cone. It was previously believed that a gapped surface implied breaking… Expand

Superpotentials for Quiver Gauge Theories

- P. Aspinwall, L. Fidkowski
- Physics
- 3 June 2005

We compute superpotentials for quiver gauge theories arising from marginal D-Brane decay on collapsed del Pezzo cycles S in a Calabi-Yau X. This is done using the machinery of A{sub {infinity}}… Expand

Local Commuting Projector Hamiltonians and the Quantum Hall Effect

- A. Kapustin, L. Fidkowski
- Physics, MathematicsCommunications in Mathematical Physics
- 17 October 2018

We prove that neither Integer nor Fractional Quantum Hall Effects with nonzero Hall conductivity are possible in gapped systems described by Local Commuting Projector Hamiltonians.
