Field of Scientific Interest:

• Lattice dynamics, surface waves, heat transfer between different media and Fano resonance, quasi-particle spectra and their physical characteristics in quasi-low-dimensional systems with defects, polaron in semiconductors.
• Propagation and localization of vibrations in infinite and semi-infinite crystals, surface waves, heat exchange between different media.
• Dynamics of strongly anisotropic crystal structures and quasi-low-dimensional lattices.
• Quasiparticle spectra and oscillation characteristics of nanoclusters and other nanosystems.
• Phonon spectra and low-temperature oscillation characteristics of one-dimensional nanodrops in carbon nanotubes.
• The influence of impurities on the vibrational properties of linear chains formed by inert gas atoms in grooves on the surface of carbon nanoribbons.
• Mechanisms of structural transition in BEDT-TTF organic compounds.

Main Achievements:

• The Kapitsa thermal resistance mechanism was proposed.
• The conditions for the creation and characteristics of localized states associated with point impurities and continuous defects (twins, interfaces, adsorbed layers, etc.) were investigated and analyzed.
• Shear waves localized near a monoatomic layer adsorbed on the free surface of a strongly anisotropic layered crystal were studied at the microscopic level using a vector lattice model with translational and rotational invariance and elastic stability. It has been shown that in some cases, non-central interatomic interactions lead to the appearance of a special type of surface shear waves with one or two endpoints and an attenuation parameter that is a non-monotonic function of the two-dimensional wave vector.
• Using the capillary effect theory, we studied multi-channel resonant phonon transfer through a point contact interface. We showed that abnormal peaks of reduced heat flow at low temperatures are induced by resonant phonon transfer through different layers of impurity atoms. The characteristics of phonon heat flow channels were calculated. The obtained data are in good agreement with experimental results.
• The properties of polarons in functionalized nanowires were investigated.
• Surface waves, heat exchange between different media, and Fano resonance were investigated at the microscopic level, quasiparticle spectra and the physical characteristics of quasidimensional systems with defects, the peculiarities of crystals with complex defect structures, micro- and nano-objects, disordered compounds, and inert gas atoms adsorbed on the surface of graphene nanobandles.
• Visual models of various compounds have been proposed that are well consistent with the actual properties of materials and combine microscopic and mesoscopic descriptions; discrepancies between theory and experiment in crystalline N₂ and surface acoustics have been eliminated; Recommendations have been developed for the practical use of ferroelectric organic stacks, graphene-organic heterostructures, and doped graphene, which has contributed to the development of applied physics of low-dimensional materials.
• Surface waves, phonons in graphene and graphite, localized and quasi-localized states in doped graphene, phase transitions in BEDT-TTF under the action of impurities, quasi-particle spectra and their physical characteristics in quasi-low-dimensional systems with defects have been investigated.
