Abstract
QFTs with local topological operators feature unusual sectors called "universes," which are separated by infinite-tension domain walls. We show that such systems have relevant deformations with exactly-calculable effects. These deformations allow one to dial the vacuum energy densities of the universes. We describe applications of these deformations to confinement in 2d gauge theories, as well as a curious violation of the effective field theory naturalness principle.
List of changes
-Fixed various typos and defined quantities that had been used without explanation.
-Added Footnote 1 to clarify a point raised by the second referee: we consider bases for local topological operators such that the zero operator does not appear in the fusion rules.
