- To develop a universal approach to describing the thermal conductivity of solids, based on experimental verification of predictions of quantum field theory in the case of isobaric and isochoric thermal conductivity; - To investigate the temperature dependencies of the thermal conductivity of a strongly anisotropic crystal and identify the contribution of quantum tunneling; - To upgrade the experimental setup for measuring the isochoric thermal conductivity: make a highpressure measuring cell, install and automate it. - To create a platform for discussing on the topic "Thermal conductivity of solids" on the International Advanced Study Conference CONDENSED MATTER & LOW TEMPERATURE PHYSICS; - To investigate the temperature dependencies of the isochoric thermal conductivity of amorphous glycerol, ABS polymer material, graphene polymer composite and identify the contribution of quantum tunneling; - To develop an empirical universal approach to the description of thermal conductivity.
