Lattice simulation of the SU(2) chiral model at zero and non-zero pion density
Tobias Rindlisbacher, Philippe de Forcrand
We propose a flux representation based lattice formulation of the partition function corresponding to the SU(2) principal chiral Lagrangian, including a chemical potential and scal…
Effects of higher dimension operators on the Standard Model Higgs sector
Oscar Akerlund, Philippe de Forcrand, Jakob Steinbauer
We study the effect of higher dimension operators on the electroweak finite temperature phase transition in two sectors of the Standard Model. Firstly, the Higgs-Yukawa sector, con…
Topological Susceptibility from Slabs
Wolfgang Bietenholz, Philippe de Forcrand, Urs Gerber
In quantum field theories with topological sectors, a non-perturbative quantity of interest is the topological susceptibility chi_t. In principle it seems straightforward to measur…
Two-Flavor Lattice QCD with a Finite Density of Heavy Quarks: Heavy-Dense Limit and "Particle-Hole" Symmetry
Tobias Rindlisbacher, Philippe de Forcrand
We investigate the properties of the half-filling point in lattice QCD (LQCD), in particular the disappearance of the sign problem and the emergence of an apparent particle-hole sy…
Higgs-Yukawa model with higher dimension operators via extended mean field theory
Oscar Akerlund, Philippe de Forcrand
Using extended mean field theory (EMFT) on the lattice, we study properties of the Higgs-Yukawa model as an approximation of the standard model Higgs sector, and the effect of high…
Euclidean Dynamical Triangulation revisited: is the phase transition really 1st order? (extended version)
Tobias Rindlisbacher, Philippe de Forcrand
The transition between the two phases of 4D Euclidean Dynamical Triangulation [1] was long believed to be of second order until in 1996 first order behavior was found for sufficien…
Condensation phenomena in two-flavor scalar QED at finite chemical potential
Alexander Schmidt, Philippe de Forcrand, Christof Gattringer
We study condensation in two-flavored, scalar QED with non-degenerate masses at finite chemical potential. The conventional formulation of the theory has a sign problem at finite d…
