More on Electric and Magnetic Fluxes in SU(2)

Lorenz von Smekal, with Philippe de Forcrand, Oliver Jahn

The free energies of static charges and center monopoles are given by their fluxes. While electric fluxes show the universal behaviour of the deconfinement transition, the monopole…

Comparison of SO(3) and SU(2) lattice gauge theory

Philippe de Forcrand, Oliver Jahn

The Villain form of SO(3) lattice gauge theory is studied and compared to Wilson's SU(2) theory. The topological invariants in SO(3) which correspond to twisted boundary conditions…

Electric and Magnetic Fluxes in SU(2) Yang-Mills Theory

Lorenz von Smekal, with Philippe de Forcrand

We measure the free energies in SU(2) of static fundamental charges and center monopoles. Dual to temporal center fluxes, the former provide a well-defined (dis)order parameter for…

QCD simulations at small chemical potential

Ph. de Forcrand, S. Kim, T. Takaishi

Within the reweighting approach, one has the freedom to choose the Monte Carlo action so that it provides a good overlap with the finite-μmeasure but remains simple to simulate. We…

Topological flux sectors in extended U(1) gauge theory on T^4

Philippe de Forcrand, Michele Vettorazzo

We consider the 4d compact U(1) gauge theory with fundamental-adjoint action on a hypertorus. We give a full characterization of the phase diagram of this model in terms of topolog…

QCD phase diagram for small densities from simulations at imaginary mu

P. de Forcrand, O. Philipsen

We present results on the QCD phase diagram for small densities without reweighting. Our simulations are performed with an imaginary chemical potential mu_I for which the fermion d…

The ground state of three quarks

C. Alexandrou, Ph. de Forcrand, O. Jahn

We measure the static three-quark potential in SU(3) lattice gauge theory with improved accuracy, by using all available technical refinements, including Luscher-Weisz exponential…

Vortex free energies in SO(3) and SU(2) lattice gauge theory

Philippe de Forcrand, Oliver Jahn

Lattice gauge theories with gauge groups SO(3) and SU(2) are compared. The free energy of electric twist, an order parameter for the confinement-deconfinement transition which does…

Calculation of the N to Delta electromagnetic transition matrix element

C. Alexandrou, Ph. de Forcrand, Th. Lippert +5

We present results on the ratio of electric quadrupole to magnetic dipole amplitudes, , for the transition from lattice QCD. We consid…

Gauge-invariant two- and three- density correlators

C. Alexandrou, Ph. de Forcrand, A. Tsapalis

Gauge-invariant spatial correlations between two and three quarks inside a hadron are measured within quenched and unquenched QCD. These correlators provide information on the shap…

Finite temperature Z(N) phase transition with Kaluza-Klein gauge fields

K. Farakos, P. de Forcrand, C. P. Korthals Altes +2

If SU(N) gauge fields live in a world with a circular extra dimension, coupling there only to adjointly charged matter, the system possesses a global Z(N) symmetry. If the radius i…

Probing hadron wave functions in Lattice QCD

C. Alexandrou, Ph. de Forcrand, A. Tsapalis

Gauge-invariant equal-time correlation functions are calculated in lattice QCD within the quenched approximation and with two dynamical quark species. These correlators provide inf…

Modified iterative versus Laplacian Landau gauge in compact U(1) theory

Stephan Dürr, Philippe de Forcrand

Compact U(1) theory in 4 dimensions is used to compare the modified iterative and the Laplacian fixing to lattice Landau gauge in a controlled setting, since in the Coulomb phase t…

The QCD phase diagram for small densities from imaginary chemical potential

Ph. de Forcrand, O. Philipsen

We present results on the QCD phase diagram for mu_B <= pi T. Our simulations are performed with an imaginary chemical potential mu_I for which the fermion determinant is positive.…

The Laplacian Gauge Gluon Propagator in SU(N_c)

C. Alexandrou, Ph. de Forcrand, E. Follana

We examine the gluon propagator in the Laplacian gauge in quenched lattice QCD as a function of the number of colours. We observe a weak dependence on over the whole momentum…
