Landau Levels in Lattice QCD
Falk Bruckmann, Gergely Endrodi, Matteo Giordano +4
The spectrum of the two-dimensional continuum Dirac operator in the presence of a uniform background magnetic field consists of Landau levels, which are degenerate and separated by…
Scalar QCD at nonzero density
Falk Bruckmann, Jacob Wellnhofer
We study scalar QCD at nonzero density in the strong coupling limit. It has a sign problem which looks structurally similar to the one in QCD. We show first data for the reweightin…
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…
