Observer dependence of bubble nucleation and Schwinger pair production
Jaume Garriga, Sugumi Kanno, Misao Sasaki +2
Pair production in a constant electric field is closely analogous to bubble nucleation in a false vacuum. The classical trajectories of the pairs are Lorentz invariant, but it appe…

Casimir-Polder interaction between an atom and a conducting wall in cosmic string spacetime
E. R. Bezerra de Mello, V. B. Bezerra, H. F. Mota +1
The Casimir-Polder interaction potential is evaluated for a polarizable microparticle and a conducting wall in the geometry of a cosmic string perpendicular to the wall. The genera…

Destabilizing Tachyonic Vacua at or above the BF Bound
Sugumi Kanno, Misao Sasaki, Jiro Soda
It is well known that tachyonic vacua in an asymptotically Anti-de Sitter (AdS) space-time are classically stable if the mass squared is at or above the Breitenlohner and Freedman…
