Nonperturbative anharmonic phenomena in crystal lattice dynamics
M. I. Katsnelson, A. V. Trefilov
Slow dynamics of energy transfer between different phonon modes under the resonance conditions is considered. It may result in new effects in the inelastic and quasielastic neutron…

Thermal expansion and the equation of state of Ir and Rh
M. I. Katsnelson, M. Sigalas, A. V. Trefilov +1
The simplest anharmonic characteristics of Ir and Rh are discussed in the framework of a previously developed simple pseudopotential model which describes the elastic moduli, phono…

Possible scenario of the melting of metals
M. I. Katsnelson, A. V. Trefilov
A microscopic picture of the ``preparation'' of a crystal to the transition to liquid state at the approach to melting temperature is proposed. Basing on simple crystallogeometric…
