Abstract

We consider cosmological models with an arbitrary number of scalar fields non-minimally coupled to gravity and construct new integrable cosmological models. In the constructed models, the Ricci scalar is an integral of motion irrespectively of the type of metric. The general solutions of evolution equations in the spatially flat FLRW metric have been found for models with the quartic potentials.

具有任意数量标量场的可积宇宙学模型

考虑具有任意数量标量场与重力非最小耦合的宇宙学模型，构造了新的可积宇宙学模型。在所构建的模型中，里奇标量是与度量类型无关的运动积分。对于具有四次势的模型，得到了空间平面FLRW度规演化方程的通解。

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.
