Crunch from AdS bubble collapse in unbounded potentials
Kaloian D. Lozanov, Misao Sasaki
We consider a scalar field theory with a Minkowski false vacuum and an unbounded (or very deep) true vacuum. We show compelling evidence that an AdS bubble of vanishing total energ…
Self-gravitating Vector Dark Matter
Peter Adshead, Kaloian D. Lozanov
We derive the non-relativistic limit of a massive vector field. We show that the Cartesian spatial components of the vector behave as three identical, non-interacting scalar fields…
Effects of Gravitational Chern-Simons during Axion-SU(2) Inflation
Leila Mirzagholi, Eiichiro Komatsu, Kaloian D. Lozanov +1
In this paper, we examine the viability of inflation models with a spectator axion field coupled to both gravitational and SU(2) gauge fields via Chern-Simons couplings. Requiring…
