Supersymmetric Nonlinear O(3) Sigma Model on the Lattice
Raphael Flore, Daniel Körner, Andreas Wipf +1
A supersymmetric extension of the nonlinear O(3) sigma model in two spacetime dimensions is investigated by means of Monte Carlo simulations. We argue that it is impossible to cons…
Supersymmetry Breaking in Low Dimensional Models
Christian Wozar, Andreas Wipf
We analyse supersymmetric models that show supersymmetry breaking in one and two dimensions using lattice methods. Starting from supersymmetric quantum mechanics we explain the fun…
Phase diagram of the lattice G(2) Higgs Model
Björn H. Wellegehausen, Andreas Wipf, Christian Wozar
We study the phases and phase transition lines of the finite temperature G(2) Higgs model. Our work is based on an efficient local hybrid Monte-Carlo algorithm which allows for acc…
Casimir Scaling and String Breaking in G(2) Gluodynamics
Bjoern H. Wellegehausen, Andreas Wipf, Christian Wozar
We study the potential energy between static charges in G(2) gluodynamics in three and four dimensions. Our work is based on an efficient local hybrid Monte-Carlo algorithm and a m…
Effective Polyakov Loop Dynamics for Finite Temperature G(2) Gluodynamics
Bjoern H. Wellegehausen, Andreas Wipf, Christian Wozar
Based on the strong coupling expansion we obtain effective 3-dimensional models for the Polyakov loop in finite-temperature G_2 gluodynamics. The Svetitsky-Jaffe conjecture relates…
Instanton constituents and fermionic zero modes in twisted CP(n) models
Wieland Brendel, Falk Bruckmann, Lukas Janssen +2
We construct twisted instanton solutions of CP(n) models. Generically a charge-k instanton splits into k(n+1) well-separated and almost static constituents carrying fractional topo…
