On the relevance of center vortices to QCD
No full textIn a numerical experiment, we remove center vortices from an ensemble of
lattice SU(2) gauge configurations. This removal adds short-range disorder.
Nevertheless, we observe long-range order in the modified ensemble: confinement
is lost and chiral symmetry is restored (together with trivial topology),
proving that center vortices are responsible for both phenomena. As for the
Abelian monopoles, they survive but their percolation properties are lost

The interaction between center monopoles in SU(2) Yang-Mills
No full textWe 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 parameter with respect to the Wilson loop, for the
deconfinement phase transition. We observe a 3d Ising-like critical behaviour
for the dual string tension related to the spatial 't Hooft loop as a function
of the temperature
The relevance of center vortices
No full textWe show remnants of chiral symmetry breaking in the center-projected theory.
We construct and study an unambiguous definition of center vortices
A study of the 't Hooft loop in SU(2) Yang-Mills theory
No full textWe 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 phase , the spatial 't Hooft loop exhibits a
dual string tension, which vanishes at with 3D Ising-like critical
exponent
The Role of Center Vortices in QCD
No full textCenter vortices are unambiguously identified after Laplacian Center Gauge
fixing and their influence on confinement and chiral symmetry breaking is
investigated on a sample of SU(2) configurations at zero and finite
temperature
