Integrable spin systems with potential are of great interest from the point of view of theoretical and applied physics. They make it possible to obtain accurate analytical solutions and study the properties of solitons ...

In this paper, we analyzed inflation from k-essence in the framework of Horndeski gravity. In particular, we considered the models of canonical scalar field and k-essence with quadratic kinetic term. Viable inflationary ...

The paper presents studies of cement-ash binder in the composition of concrete with the use of a complex modified additive (CMA). The research is aimed at improving the conditions for the production of concrete works, ...

X-ray luminescence, photoluminescence, and vacuum ultraviolet spectroscopy have been used to study the nature of intrinsic luminescence and the formation of electron-hole trapping centers in a LiNaSO4 crystal in a broad ...

Despite the significant accomplishments of general relativity, numerous unresolved issues persist in our understanding of the cosmos. One of the most perplexing challenges is the ongoing accelerated expansion of the ...
