The entropic order parameters measure in a universal geometric way the statistics of non-local operators responsible for generalized symmetries. In this article, we compute weakly coupled gauge theories. To perform computation, natural route evaluating expectation values physical (smeared) is prevented by known difficulties constructing suitable smeared Wilson loops. We circumvent problem study...

A quantum mechanical description of particle propagation on the discrete spacetime of a causal set is presented. The model involves a discrete path integral in which trajectories within the causal set are summed over to obtain a particle propagator. The sum-over-trajectories is achieved by a matrix geometric series. For causal sets generated by sprinkling points into 1+1 and 3+1 dimensional Min...

The design of a constraint solver is certainly a complex task involving the combination of good search algorithms and efficient constraint propagation. The behavior of propagation functions for n-ary constraints rely usually on specialized graph algorithms which depend on the nature of the constraint and the level of consistency to be enforced. The design of an efficient algorithm usually requi...

We present a strong coupling expansion that permits to develop analysis of quantum field theory in the infrared limit. Application to a quartic massless scalar field gives a massive spectrum and the propagator in this regime. We extend the approach to a pure Yang-Mills theory obtaining analogous results. The gluon propagator is compared satisfactorily with lattice results and similarly for the ...
