Physicists turned back the clock

As part of the experiment, scientists turned to correlated
(interconnected) particles. Their concept is similar to the
concept of particles forming quantum entanglement
(interaction of not locally connected parts), however, they
are not so closely related to each other. The researchers
began by studying a molecule of trichloromethane: they
heated the nucleus of a hydrogen atom so that it was warmer
than the nucleus of a carbon atom, and watched the flow of
energy. When the nuclei of two atoms were in an uncorrelated
(unbound) state, heat, according to the second law of
thermodynamics, actually moved from a warmer to a colder
nucleus. However, after the correlation (not local interaction)
of the nuclei, scientists suddenly saw that the heat flowed
"back" - the heated core was getting hotter, and its colder
neighbor began to cool down. According to the researchers,
their experiment does not violate the second law of
thermodynamics, since it simply does not take into account
the correlation of particles. Successful experience is rather an
exception to the rule. An article describing the course and results
of the experiment was published on the arXiv server
(https://arxiv.org/abs/1711.03323).
For those who did not understand the meaning of the study, I will
explain. Heat cannot return back to the heating source. Because all
the energy in the universe tends to decay. This is as if a person
died, rotted away. And then he began to return to life in the
reverse order. And in the end, he will came to life. It now seems
theoretically possible.
