Deformations of infrared-conformal theories in two dimensions
Oscar Akerlund, Philippe de Forcrand
We study two exactly solvable two-dimensional conformal models, the critical Ising model and the Sommerfield model, on the lattice. We show that finite-size effects are important a…
Lattice gauge theory without link variables
Helvio Vairinhos, Philippe de Forcrand
We obtain a sequence of alternative representations for the partition function of pure SU(N) or U(N) lattice gauge theory with the Wilson plaquette action, using the method of Hubb…
The chiral phase transition in two-flavor QCD from imaginary chemical potential
Claudio Bonati, Philippe de Forcrand, Massimo D'Elia +2
We investigate the order of the finite temperature chiral symmetry restoration transition for QCD with two massless fermions, by using a novel method, based on simulating imaginary…
The lattice QCD phase diagram in and away from the strong coupling limit
Philippe de Forcrand, Jens Langelage, Owe Philipsen +1
We study lattice QCD with four flavors of staggered quarks. In the limit of infinite gauge coupling, "dual" variables can be introduced, which render the finite-density sign proble…
Extended Mean Field study of complex -theory at finite density and temperature
Oscar Akerlund, Philippe de Forcrand, Antoine Georges +1
We review the Extended Mean Field Theory (EMFT) approximation and apply it to complex, scalar -theory on the lattice. We study the critical properties of the Bose condensation…
The Phase Diagram of Strong Coupling QCD including Gauge Corrections
Philippe de Forcrand, Jens Langelage, Owe Philipsen +1
The strong coupling limit of lattice QCD with staggered fermions has been studied for decades, both via Monte Carlo and via mean field theory. In this model, the finite density sig…
