Chemical potential response of meson masses at finite temperature
TARO Collaboration, Ph. deForcrand, T. Hashimoto +7
We study the response of meson masses to the chemical potential () at high temperature and at zero chemical potential on lattice with staggered fermi…
Laplacian gauge and instantons
Ph. de Forcrand, M. Pepe
We exhibit the connection between local gauge singularities in the Laplacian gauge and topological charge, which opens the possibility of studying instanton excitations without coo…
Simulation of n_f =3 QCD by Hybrid Monte Carlo
T. Takaishi, Ph. de Forcrand
Simulations of odd flavors QCD can be performed in the framework of the hybrid Monte Carlo algorithm where the inverse of the fermion matrix is approximated by a polynomial. In thi…
The interaction between center monopoles in SU(2) Yang-Mills
Ph. de Forcrand, M. D'Elia, M. Pepe
We study the potential between a static center monopole and antimonopole in 4d SU(2) Yang-Mills theory. Using a new numerical method, we show that the 't Hooft loop is a dual order…
Noisy Monte Carlo Algorithm
T. Bakeyev, Ph. de Forcrand
We present an exact Monte Carlo algorithm designed to sample theories where the energy is a sum of many couplings of decreasing strength. The algorithm avoids the computation of al…
Odd-flavor Simulations by the Hybrid Monte Carlo
Tetsuya Takaishi, Philippe de Forcrand
The standard hybrid Monte Carlo algorithm is known to simulate even flavors QCD only. Simulations of odd flavors QCD, however, can be also performed in the framework of the hybrid…
A study of center vortices in SU(2) and SU(3) gauge theories
M. Pepe, Ph. de Forcrand
We show how center vortices and Abelian monopoles both appear as local gauge ambiguities in the Laplacian Center gauge. Numerical results, for SU(2) and SU(3), support the view tha…
Noisy Monte Carlo revisited
T. Bakeyev, Ph. de Forcrand
We present an exact Monte Carlo algorithm designed to sample theories where the energy is a sum of many couplings of decreasing strength. Our algorithm, simplified from that of L.…
Meson Correlators in Finite Temperature Lattice QCD
TARO Collaboration, Ph. de Forcrand, M. Garcia Perez +8
We analyze temporal and spatial meson correlators in quenched lattice QCD at T>0. Below T_c we observe little change in the meson properties as compared with T=0. Above T_c we obse…
Center Vortices and Monopoles without lattice Gribov copies
Ph. de Forcrand, M. Pepe
We construct a smooth gauge for the adjoint field which is free of ambiguities on the lattice. In this Laplacian Center Gauge, center vortices and monopoles appear together as loca…
The Gluon Propagator without lattice Gribov copies
C. Alexandrou, Ph. de Forcrand, E. Follana
We study the gluon propagator in quenched lattice QCD using the Laplacian gauge which is free of lattice Gribov copies. We compare our results with those obtained in the Landau gau…
A study of the 't Hooft loop in SU(2) Yang-Mills theory
Ph. de Forcrand, M. D'Elia, M. Pepe
We study the behaviour of the spatial and temporal 't Hooft loop at zero and finite temperature in the 4D SU(2) Yang-Mills theory, using a new numerical method. In the deconfined p…
Adjoint string breaking in 4d SU(2) Yang-Mills theory
Ph. de Forcrand, O. Philipsen
We compute the static potential of adjoint sources in SU(2) Yang-Mills theory in four dimensions by numerical Monte Carlo simulations. Following a recent calculation in 2+1 dimensi…
