Finite Density Condensation and Scattering Data: A Study in ${\varphi}^{4}$ Lattice Field Theory
/ Gattringer, Christof ; Giuliani, Mario ; Orasch, Oliver
We study the quantum field theory of a charged ${\varphi}^{4}$ field in lattice regularization at finite density and low temperature in 2 and 4 dimensions with the goal of analyzing the connection of condensation phenomena to scattering data in a nonperturbative way. [...]

Simulation strategies for the massless lattice Schwinger model in the dual formulation
/ Göschl, Daniel ; Gattringer, Christof ; Lehmann, Alexander ; Weis, Christoph
The dual form of the massless Schwinger model on the lattice overcomes the complex action problems from two sources: a topological term, as well as nonzero chemical potential, making these physically interesting cases accessible to Monte Carlo simulations. [...]
