Biography: Alexi Gerasimov


The first attempt at scientific study of phenomena taking place in the matter – Thermodynamics, it considering  the substance  as a continuous substance but failed to explain many phenomena observed at that time. There was a need to move to new views which considered the substance at molecular-atomic level – molecular kinetic theory (MKT). However, over the last 40-50 years, there have been accumulated experimental data which cannot be explained by the MKT even qualitatively observed in substances not only of nanoscale size but also of ordinary size. In the case of cryogenic temperatures, it is absolutely powerless. It unambiguously points out that for elimination of this shortcoming the transition to new physical concepts is needed. We are offering new ideas for studying the substance at more processional-electron level, i.e. molecular potential theory (MPT) which takes into account the state of chemical bonds. Electrons participating in the creation of chemical bonds can be in two quantum states: the bonding and antibonding states. The electron in antibonding zone and the hole in the bonding zone are antibonding quasi particles (AQP). The transfer of an electron from the bonding into antibonding zone means the formation of AQP that weakens the chemical bonds between atoms around which it appears during its chaotic motion making easier the change in the location of atoms. The concentration of the AQP can be varied both by temperature and athermic way and size reduction in nanoscale sample. The latter opens up new technological opportunities. The examples confirming the above views are given.
