Archimedes: A feasibility study of an experiment to weigh the electromagnetic vacuum

E. Calloni, S. Caprara, M. Grilli, E. Majorana et autres

Archimedes is a feasibility study of a future experiment to ascertain the interaction of vacuum fluctuations with gravity. The experiment should measure the force that the earth's gravitational field exerts on a Casimir cavity by using a small force detector. Here we …

Casimir energy for two and three superconducting coupled cavities

Luigi Rosa, S. Avino, E. Calloni, S. Caprara et autres

In this paper we study the behavior of the Casimir energy of a "multi-cavity" across the transition from the metallic to the superconducting phase of the constituting plates. Our analysis is carried out in the framework of the ARCHIMEDES experiment, aiming at …

How To Fix Non-Perturbatively A Parameter Dependent Covariant Gauge On The Lattice

Leonardo Giusti, M.L. Paciello, S. Petrarca, B. Taglienti

We describe how to overcome some problems that usually prevent from obtaining an efficient algorithm to fix a generic covariant gauge on the lattice. This gauge is the lattice equivalent of the generic gauge usually adopted in perturbative calculations. It depends on …

Color structure of Yang-Mills theory with static sources in a periodic box

Leonardo Giusti, Andrea L. Guerrieri, S. Petrarca, Argia Rubeo et autres

We present an exploratory numerical study on the lattice of the color structure of the wave functionals of the SU(3) Yang--Mills theory in the presence of a $q\overline{q}$ static pair. In a spatial box with periodic boundary conditions, we discuss the fact …
