Continuum extrapolation of Ward identities in supersymmetric SU(3) Yang-Mills theory
Sajid Ali, Georg Bergner, Henning Gerber +4
In supersymmetric Yang-Mills theory, regularised on a space-time lattice, in addition to the breaking by the gluino mass term, supersymmetry is broken explicitly by…
Continuum limit of SU(3) supersymmetric Yang-Mills theory and supersymmetric gauge theories on the lattice
Sajid Ali, Georg Bergner, Henning Gerber +5
We summarize our investigations of several aspects of supersymmetric Yang-Mills (SYM) theory. We present our final results for SU(3) SYM simulated w…
Numerical results for the lightest bound states in supersymmetric SU(3) Yang-Mills theory
Sajid Ali, Georg Bergner, Henning Gerber +4
The physical particles in supersymmetric Yang-Mills theory (SYM) are bound states of gluons and gluinos. We have determined the masses of the lightest bound states in SU(3) $\mathc…
Variational analysis of low-lying states in supersymmetric Yang-Mills theory
Sajid Ali, Georg Bergner, Henning Gerber +5
We have calculated the masses of bound states numerically in N = 1 supersymmetric Yang-Mills theory with gauge group SU(2). Using the suitably optimised variational method with an…
Baryonic states in supersymmetric Yang-Mills theory
Sajid Ali, Georg Bergner, Henning Gerber +5
In =1 supersymmetric Yang-Mills theory the superpartner of the gluon is the gluino, which is a spin 1/2 Majorana particle in the adjoint representation of the gauge gr…
Analysis of Ward identities in supersymmetric Yang-Mills theory
Sajid Ali, Georg Bergner, Henning Gerber +4
In numerical investigations of supersymmetric Yang-Mills theory on a lattice, the supersymmetric Ward identities are valuable for finding the critical value of the hopping paramete…
The light bound states of supersymmetric SU(3) Yang-Mills theory on the lattice
Sajid Ali, Georg Bergner, Henning Gerber +5
In this article we summarise our results from numerical simulations of supersymmetric Yang-Mills theory with gauge group SU(3). We use the formulation of Curci and…
Ward identities in supersymmetric SU(3) Yang-Mills theory on the lattice
Sajid Ali, Georg Bergner, Henning Gerber +5
The introduction of a space-time lattice as a regulator of field theories breaks symmetries associated with continuous space-time, i.e.\ Poincar{é} invariance and supersymmetry. A…
Supermultiplets in N=1 SUSY SU(2) Yang-Mills Theory
Sajid Ali, Georg Bergner, Henning Gerber +6
We study supersymmetric Yang-Mills theory (SYM) on the lattice. The non-perturbative nature of supersymmetric field theories is still largely unknown. Similarly to…
Improved results for the mass spectrum of N=1 supersymmetric SU(3) Yang-Mills theory
Sajid Ali, Georg Bergner, Henning Gerber +6
This talk summarizes the results of the DESY-Münster collaboration for supersymmetric Yang-Mills theory with the gauge group SU(3). It is an updated status report w…
Simulations of N=1 supersymmetric Yang-Mills theory with three colours
Sajid Ali, Georg Bergner, Henning Gerber +4
We report on our recent results regarding numerical simulations of the four dimensional, N=1 Supersymmetric Yang-Mills theory with SU(3) gauge symmetry and light dynamical gluinos.
Appearance of flat surface bands in three-dimensional topological insulators in a ferromagnetic exchange field
Tomi Paananen, Henning Gerber, Matthias Götte +1
We study the properties of the surface states in three-dimensional topological insulators in the presence of a ferromagnetic exchange field. We demonstrate that for layered materia…
