Никонов Э.Г., Назмитдинов Р.Г., Глуховцев П.И. Квазидвумерные системы играют важную роль при создании различных устройств для нужд наноэлектроники. Очевидно, что функциональная эффективность таких систем зависит от их структуры, которая может изменяться при фазовых переходах под действием внешних условий (например, температуры). До настоящего времени основное внимание было сосредоточено на поиске сигналов фазовых переходов …

E. G. Nikonov, R. G. Nazmitdinov and P. I. Glukhovtsev Quasi-two-dimensional systems play an important role in the manufacture of various devices for the needs of nanoelectronics. Obviously, the functional efficiency of such systems depends on their structure, which can change during phase transitions under the influence of external conditions …

В.Воронюк (снс, ЛФВЭ), Н.С.Цегельник (стажер-исследователь, ЛТФ), Е.Э.Коломейцев (внс, ЛТФ) The strange baryon production in Bi + Bi collisions at √sNN = 9.0 GeV is studied using the PHSD transport model. Hyperon and anti-hyperon yields, transverse momentum spectra, and rapidity spectra are calculated, and their centrality dependence and the effect of …

M. Kozhevnikova and Yu. B.
