We consider the two-dimensional N=(2, 2) Wess-Zumino model with a cubic superpotential
at weak and intermediate couplings. Refined algorithms allow for the extraction of reliable …

Lattice Wess-Zumino model with Ginsparg-Wilson fermions:<? format?> One-loop results and GPU benchmarks

Wess-Zumino model on the Euclidean lattice

K Fujikawa - Physical Review D, 2002 - APS
We examine the N= 2 Wess-Zumino model defined on the d= 2 Euclidean lattice in
connection with a restoration of the Leibniz rule in the limit a→ 0 in perturbatively finite …

Exact lattice Ward-Takahashi identity for the Wess-Zumino model

M Bonini, A Feo - Physical Review D—Particles, Fields, Gravitation, and …, 2005 - APS
We consider a lattice formulation of the four-dimensional N= 1 Wess-Zumino model that
uses the Ginsparg-Wilson relation. This formulation has an exact supersymmetry on the …

Supersymmetry breaking in two dimensions: The lattice Wess-Zumino model

M Beccaria, M Campostrini, A Feo - Physical Review D, 2004 - APS
We study dynamical supersymmetry breaking by nonperturbative lattice techniques in a

Supersymmetry on a lattice

J Bartels, JB Bronzan - Physical Review D, 1983 - APS
Abstract We develop Lagrangian and Hamiltonian lattice formulations of the Wess-Zumino
model which preserve the superalgebra. We check that the lattice model passes into the …

Spontaneous Supersymmetry Breaking in the 2D Wess-Zumino Model

K Steinhauer, U Wenger - Physical review letters, 2014 - APS
We study the phase diagram of the two-dimensional N= 1 Wess-Zumino model on the lattice
using Wilson fermions and the fermion loop formulation. We give a complete …

M Bonini, A Feo - Journal of High Energy Physics, 2004 - iopscience.iop.org
A lattice formulation of the four dimensional Wess-Zumino model that uses Ginsparg-Wilson
fermions and keeps exact supersymmetry is presented. The supersymmetry transformation …

From the Dirac operator to Wess–Zumino models on spatial lattices

A Kirchberg, JD Länge, A Wipf - Annals of Physics, 2005 - Elsevier
We investigate two-dimensional Wess–Zumino models in the continuum and on spatial
lattices in detail. We show that a non-antisymmetric lattice derivative not only excludes chiral …
