Abstract
The usual Minkowski vacuum in an accelerated frame of reference is known to look like a “thermal bath” of particles. This effect is well known and called the Unruh effect, and is an analog of Hawking radiation in space with zero curvature. Thus, the Minkowski vacuum looks like a heated medium from the point of view of an accelerated observer, and the natural goal is to study the properties of such a medium in more detail. We show that if the Minkwoski vacuum is cooled, and we achieve a temperature below the Unruh temperature, then a phase transition occurs associated with the “fall beyond the horizon” of the lower Matsubara modes. This transition has many remarkable features, for example, for massless particles it is “polynomial,” and is also associated with the breaking of conformal symmetry.
期刊介绍：
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
