Boris Kochelaev

Kochelaev was born in Dirizhablestroy (now Dolgoprudny), USSR. He graduated from the Physics and Mathematics Faculty of the Kazan University in 1957. From 1957 to 1960, Kochelaev was a post-graduate student of the Experimental and Theoretical Physics Department of Kazan University under the supervision of Semen Altshuler. He defended his candidate's (Ph.D.) dissertation in 1960 in Kharkov State University, and his doctor's dissertation in 1968. From 1968 until now Boris Kochelaev is a professor and from 1973 to 2000 is a chair of Kazan University's Theoretical Physics Department.

He is an author of more than 150 scientific works. 33 PhD-level scientists were supervised by Kochelaev, 10 of them have obtained the Doctoral degrees and become full professors.

The research interests are focused on electron spin resonance and spin dynamics in condensed matter, superconductivity, propagation of the sound in resonant media, and light scattering in solids.

Major research achievements:

• The development of spin-phonon interactions in paramagnetic crystals:[1] [2]
• The non-linear theory of kinetic processes in paramagnetic crystals explained the experimentally observed phonon avalanche and super-scattering of light under saturation on the wing of the EPR line[3] [4]
• The prediction of the discovered later effect of non-resonant sound absorption and its giant amplification by radio-frequency fields
• The theory of EPR and spin relaxation in conventional superconductors with paramagnetic impurities [5][6][7]
• The theory of spin kinetics and magnetic resonance in usual and high-T_c superconductors[8][9] and Kondo systems with heavy fermions.[10]

These last theoretical investigations are best described by the Nobel Prize winner Prof. K. Alex Müller in the paper titled "The Impact of ESR (EPR) on the Understanding of the Cuprates and Their Superconductivity":

this important advance was achieved by the experimental results at the universities of Darmstadt and Zürich on the one side and the deep theoretical insight of Boris Kochelaev at the Kazan State University explaining them on the other side.[11]
