On the Possible Anisotropy of the Unruh Radiation. Part II: Massive Scalar Field in \(\boldsymbol{(3+1)}\)D Space-Time
The Unruh effect for a massive scalar field in \((3+1)\)D space-time is considered in the case of accelerated motion with a certain starting instant. A stationary energy-angular distribution of the corresponding Unruh radiation to be observed by a two-opposite-horn antenna is obtained. It is shown that this distribution is significantly anisotropic, and the Unruh radiation cannot be considered as thermal (equilibrium) radiation. It is also shown that Fulling modes are not completely relevant wave functions for the description of particles in semi-eternal Rindler space-time. More appropriate candidates are suggested for this aim.
期刊介绍：
Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoples’ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
