Abstract

Tunneling between degenerate vacua is allowed in finite-volume quantum field theory, and it features remarkable energetic properties, which result from the competition of different dominant configurations in the partition function. We derive the one-loop effective potential based on two homogeneous vacua of the bare theory, and we discuss the resulting null energy condition violation in O(4)-symmetric Euclidean spacetime, as a result of a nonextensive effective action.
