“…Стандартная модель сегодня -является общепризнанной и лучшей теорией, описывающей фундаментальные взаимодействия [29]. Однако, в современной физике накопилось немало разнообразных проблем, которые требуют своего разрешения [30,31,32]. Помимо вышеуказанных, это прежде всего: наблюдаемая барионная асимметрия во Вселенной [33,34].…”

“…Nowadays, the Standard Model is universally recognized and is accepted as the best theory describing fundamental interactions [29]. However, in modern physics, a significant number of problems have accumulated that need to be resolved [30,31,32]. In addition to the above, it is primarily these problems and questions: observed baryonic asymmetry in the Universe [33,34]; Why, despite the inviolability of the second law of thermodynamics, we do not observe the thermal death of the Universe [35,36]?…”

The two-dimensional ferromagnetic Kondo model with classical core spins is studied via unbiased Monte Carlo simulations for a hole doping up to x = 12.5%. A canonical algorithm for finite temperatures is developed. We show that, with realistic parameters for the manganites and at low temperatures, the double-exchange mechanism does not lead to phase separation on a twodimensional lattice but rather stabilizes individual ferromagnetic polarons for this doping range. A detailed analysis of unbiased Monte Carlo results reveals that the polarons can be treated as independent particles for these hole concentrations. It is found that a simple polaron model describes the physics of the ferromagnetic Kondo model amazingly well. The ferromagnetic polaron picture provides an obvious explanation for the pseudogap in the one-particle spectral function A k (ω) observed in the ferromagnetic Kondo model.
