Study of thermodynamic properties of low-dimensional many-boson and many-fermion systems with different types of short-range interactions between particles. Identification of the conditions for the emergence of universality in 3- and 4-particle physics of systems with bounded geometry and in fractional dimensions, and elucidation of the role of few-particle quantum effects in shaping the properties of macroscopic systems. Development of new models of fractional statistics. Formulation of quantum-statistical bases of the description of interrelation between the observed phenomena in heterostructures and their parameters. popup.nrat_date 2024-12-09 Close
