Casimir Force in Spacetimes with Torsion
M. W. AlMasri
We compute the Casimir force between perfectly conducting parallel plates in a spacetime endowed with constant axial torsion. Working within an effective field theory framework whe…

Fate of false vacuum in non-perturbative regimes: Gravity effects
Gianluca Calcagni, Marco Frasca, Anish Ghoshal
A recent analysis of the false-vacuum decay in non-perturbative regimes is here extended in the presence of Einstein gravity, computing the corresponding effective potential and de…
