Mapping Hawking into Unruh Thermal Properties
S. Deser, Orit Levin
By globally embedding curved spaces into higher dimensional flat ones, we show that Hawking thermal properties map into their Unruh equivalents: The relevant curved space detectors…
Equivalence of Hawking and Unruh Temperatures and Entropies Through Flat Space Embeddings
S. Deser, Orit Levin
We present a unified description of temperature and entropy in spaces with either "true" or "accelerated observer" horizons: In their (higher dimensional) global embedding Minkowsk…
Accelerated Detectors and Temperature in (Anti) de Sitter Spaces
S. Deser, Orit Levin
We show, in complete accord with the usual Rindler picture, that detectors with constant acceleration in de Sitter (dS) and Anti de Sitter (AdS) spaces with cosmological consta…
Quantum Field Theory with Null-Fronted Metrics
Orit Levin, Asher Peres
There is a large class of classical null-fronted metrics in which a free scalar field has an infinite number of conservation laws. In particular, if the scalar field is quantized,…
