Vortex characterisation of frustration in the 2d Ising spin glass
K. Langfeld, M. Quandt, W. Lutz +1
The frustrated Ising model on a two-dimensional lattice with open boundary conditions is revisited. A hidden Z2 gauge symmetry relates models with different frustrations which, how…

Is the ground state of Yang-Mills theory Coulombic?
Thomas Heinzl, Anton Ilderton, Kurt Langfeld +3
We study trial states modelling the heavy quark-antiquark ground state in SU(2) Yang-Mills theory. A state describing the flux tube between quarks as a thin string of glue is found…

A gauge invariant cluster algorithm for the Ising spin glass
K. Langfeld, M. Quandt, W. Lutz +1
The frustrated Ising model in two dimensions is revisited. The frustration is quantified in terms of the number of non-trivial plaquettes which is invariant under the Nishimori gau…
