Quantization of unstable linear scalar fields in static spacetimes
William C. C. Lima
We discuss the quantization of an unstable field through the construction of a "one-particle Hilbert space." The system considered here is a neutral scalar field evolving over a gl…

Awaking the vacuum with spheroidal shells
William C. C. Lima, Raissa F. P. Mendes, George E. A. Matsas +1
It has been shown that well-behaved spacetimes may induce the vacuum fluctuations of some nonminimally coupled free scalar fields to go through a phase of exponential growth. Here,…
