Two observers calculate the trace anomaly
A. Z. Capri, M. Kobayashi, D. J. Lamb
We adapt a calculation due to Massacand and Schmid to the coordinate independent definition of time and vacuum given by Capri and Roy in order to compute the trace anomaly for a ma…
Finite particle creation in 3+1 de Sitter space
D. J. Lamb, A. Z. Capri, M. Kobayashi
In this paper we calculate the particle creation as seen by a stationary observer in 3+1 de Sitter space. This particle creation is calculated using an observer dependent geometric…
Finite particle creation in 1+1 dim. compact in space
D. J. Lamb, A. Z. Capri
In this paper we calculate the massive particle creation as seen by a stationary observer in a dimensional spacetime compact in space. The Bogolubov transformation relating t…
Discrete spectral shift in an anisotropic universe
D. J. Lamb, A. Z. Capri, M. Kobayashi
In this paper we calculate the particle creation as seen by a stationary observer in an anisotropic universe. By using an observer and geometry dependent time to quantise a massive…
Massive particle creation in a static 1+1 dimensional spacetime
D. J. Lamb, A. Z. Capri, S. M. Roy
We show explicitly that there is particle creation in a static spacetime. This is done by studying the field in a coordinate system based on a physical principle which has recently…
Massless scalar fields in 1+1 dimensions and Krein spaces
A. Z. Capri, R. Ferrari, V. Montalbano
We consider the Krein realization of the Hilbert space for a massless scalar field in 1+1 dimensions. We find convergence criteria and the completion of the space of test functions…
