The helicity modulus in gauge field theories
Michele Vettorazzo, Philippe de Forcrand
We consider the 4d compact U(1) theory with Wilson action and characterize its phase diagram using the notion of electromagnetic flux, instead of the more usual magnetic monopole.…
Electromagnetic fluxes, monopoles, and the order of the 4d compact U(1) phase transition
Michele Vettorazzo, Philippe de Forcrand
We consider the 4d compact U(1) gauge theory with extended action S=-beta sum_P cos theta_P -gamma sum_P cos 2 theta_P We give a full characterization of the phase diagram of this…
Deconfinement transition in 2+1-dimensional SU(4) lattice gauge theory
Philippe de Forcrand, Oliver Jahn
A missing piece is added to the Svetitsky-Yaffe conjecture. The spin model in the same universality class as the (2+1)d SU(4) theory, the 2d Ashkin-Teller model, has a line of cont…
QCD at zero baryon density
Slavo Kratochvila, Philippe de Forcrand
While the grand canonical partition function Z_{GC}(mu) with chemical potential mu explicitly breaks the Z_3 symmetry with the Dirac determinant, the canonical partition function a…
Baryons and confining strings
Oliver Jahn, Philippe de Forcrand
The subleading term of the heavy quark potential (the analogue of the Luscher term) is computed in a string model for the case of three quarks. It turns out to be positive in 2+1 d…
The phase diagram of N_f=3 QCD for small baryon densities
Ph. de Forcrand, O. Philipsen
We demonstrate how to locate the critical endpoint of the QCD phase transition by means of simulations at imaginary μ. For the three flavor theory, we present numerical results for…
