A geometrical approach to N = 2 super Yang-Mills theory on the two dimensional lattice

- S. Catterall
- Physics
- 28 October 2004

We propose a discretization of two dimensional Euclidean Yang-Mills theories with N = 2 supersymmetry which preserves exactly both gauge invariance and an element of supersymmetry. The approach… Expand

Exact Lattice Supersymmetry: the Two-Dimensional N = 2 Wess-Zumino Model

- S. Catterall, S. Karamov
- Physics
- 16 August 2001

We study the two-dimensional Wess-Zumino model with extended $N=2$ supersymmetry on the lattice. The lattice prescription we choose has the merit of preserving exactly a single supersymmetric… Expand

Stripes from (non-commutative) stars

- J. Ambjorn, S. Catterall
- Physics
- 10 September 2002

We show that lattice regularization of non-commutative field theories can be used to study non-perturbative vacuum phases. Specifically we provide evidence for the existence of a striped phase in… Expand

Thermal phases of D1-branes on a circle from lattice super Yang-Mills

- S. Catterall, Anosh Joseph, T. Wiseman
- Physics
- 29 August 2010

We report on the results of numerical simulations of 1 + 1 dimensional SU(N) Yang-Mills theory with maximal supersymmetry at finite temperature and compactified on a circle. For large N this system… Expand

Phase diagram of SU(2) with 2 flavors of dynamical adjoint quarks

- S. Catterall, J. Giedt, Francesco Sannino, J. Schneible
- Physics
- 4 July 2008

We report on numerical simulations of SU(2) lattice gauge theory with two flavors of light dynamical quarks in the adjoint of the gauge group. The dynamics of this theory is thought to be very… Expand

First results from simulations of supersymmetric lattices

- S. Catterall
- Physics
- 7 November 2008

We conduct the first numerical simulations of lattice theories with exact super- symmetry arising from the orbifold constructions of (1, 2, 3). We consider the Q = 4 theory in D = 0,2 dimensions and… Expand

Lattice supersymmetry and topological field theory

- S. Catterall
- Physics
- 28 January 2003

It is known that certain theories with extended supersymmetry can be discretized in such a way as to preserve an exact fermionic symmetry. In the simplest model of this kind, we show that this… Expand

Lattice Formulation of {\cal N}=4 Super Yang-Mills Theory

- S. Catterall
- Physics
- 26 March 2005

We construct a lattice action for ${\cal N}=4$ super Yang-Mills theory in four dimensions which is local, gauge invariant, free of spectrum doubling and possesses a single exact supersymmetry. Our… Expand

A lattice path integral for supersymmetric quantum mechanics

- S. Catterall, E. Gregory
- Physics
- 13 June 2000

Abstract We report on a study of the supersymmetric anharmonic oscillator computed using a euclidean lattice path integral. Our numerical work utilizes a Fourier accelerated hybrid Monte Carlo scheme… Expand

Black hole thermodynamics from simulations of lattice Yang-Mills theory

- S. Catterall, T. Wiseman
- Physics
- 29 March 2008

We report on lattice simulations of 16 supercharge SU(N) Yang-Mills quantum mechanics in the 't Hooft limit. Maldacena duality conjectures that in this limit the theory is dual to IIA string theory,… Expand
