Abstract

Acoustic space-times have been known to offer analogue models for black hole physics and cosmology. Within this context, aspects of analogue quantum field theories in curved space-time are studied. In particular, some new comments have been made on the analogue Hawking temperature including a quick derivation of the result. Further, analogue cosmology is explored, within which an acoustic version of the Parker–Toms model is proposed, and the corresponding quantities are calculated. The limits of the acoustic analogue are emphasized.

关于（$$\boldsymbol{1+1}$$）维度中模拟半经典引力的说明

众所周知，声学时空为黑洞物理学和宇宙学提供了模拟模型。在此背景下，我们研究了弯曲时空中类似量子场论的各个方面。特别是，对模拟霍金温度做了一些新的评论，包括对结果的快速推导。此外，还探讨了模拟宇宙学，其中提出了帕克-汤姆斯模型的声学版本，并计算了相应的量。强调了声学模拟的局限性。

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 Peoplesâ€™ 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
