Phase diagram of the two-dimensional O(3) model from dual lattice simulations
Falk Bruckmann, Christof Gattringer, Thomas Kloiber +1
We have simulated the asymptotically free two-dimensional O(3) model at nonzero chemical potential using the model's dual representation. We first demonstrate how the latter solves…
The two-dimensional O(3) model at nonzero density: from dual lattice simulations to repulsive bosons
Falk Bruckmann, Christof Gattringer, Thomas Kloiber +1
We discuss the thermodynamics of the O(3) nonlinear sigma model in 1+1 dimensions at nonzero chemical potential (equivalent to a magnetic field). In its conventional field theory r…
Scalar QED with a topological term - a lattice study in a dual representation
Thomas Kloiber, Christof Gattringer
We present a dual representation for the partition function of 2-dimensional scalar quantum electrodynamics with a topological term (-term). In the dual representation the compl…
