Abstract: 

A vibrational model of heat transfer in simple liquids with soft pairwise interatomic interactions is discussed. A general expression is derived, which involves an averaging over the liquid collective mode excitation spectrum. The model is applied to quantify heat transfer in three-dimensional strongly coupled one-component plasma and Yukawa (screened Coulomb) fluids as well as dense Lennard-Jones liquids. Remarkable agreement with the available numerical results is documented. Some comments on the applicability of this model to heat conduction in two-dimensional liquids are made. Perspectives are briefly discussed.

Brief CV of Dr. Sergey A. Khrapak: 

Sergey Khrapak received the M.Sc. and Ph.D. degrees in physics from the Moscow Institute of Physics and Technology, Moscow, Russia, in 1996 and 1999, respectively. From 1996 to 2000, he was a Research Fellow with the Joint Institute for High Temperatures, Russian Academy of Sciences, Moscow. From 2000 to 2014, he was with the Theory (complex plasma) Group at Max-Planck-Institute for Extraterrestrial Physics, Garching, Germany. Since 2014, he has been with the Complex Plasma Group at German Aerospace Centre (DLR), Wessling, Germany. From 2015 to 2018 he was also appointed as Chair of Excellence at PIIM Laboratory, Aix-Marseille-University, Marseille, France. His current affiliation is with the Joint Institute for High Temperatures in Moscow. He is the author of more than 200 scientific publications. His current scientific interests are mostly focused on the interface between soft condensed matter, physics of fluids and physics of plasmas.
