Counting gauge-invariant states with matter fields and finite gauge groups
Alessandro Mariani
Gauge theories with finite gauge groups have applications to quantum simulation and quantum gravity. Recently, the exact number of gauge-invariant states was computed for pure gaug…

The finite temperature ground state energy of the confining string in three-dimensional U(1) gauge theory
M. Caselle, A. Mariani
The three-dimensional U(1) gauge theory displays a peculiar form of confinement which does not fit in the standard paradigm of effective string theory. In this work, we report resu…

On the equation of state of U(1) lattice gauge theory in three dimensions
Michele Caselle, Alessandro Mariani, Marco Panero +1
We study the equation of state of three-dimensional compact U(1) gauge theory on the lattice by means of numerical simulations, and discuss the implications of our results for the…
