Dual Methods for Lattice Field Theories at Finite Density
Thomas Kloiber, Christof Gattringer
We present a dual representation of the partition function of the charged scalar field in which the complex action problem at non-zero chemical potential is absent. In this dual re…

Spectroscopy in finite density lattice field theory: An exploratory study in the relativistic Bose gas
Christof Gattringer, Thomas Kloiber
We analyze 2-point functions in the relativistic Bose gas on the lattice, i.e., a charged scalar phi-4 field with chemical potential mu. Using a generalized worm algorithm we perfo…
