Incipience of quantum chaos in the Jahn-Teller model
E. Majernikova, Serge Shpyrko
We studied complex spectra of a two-level electron system coupled to two phonon (vibron) modes represented by the Ee Jahn-Teller model. For particular rotation quantum num…

Nonequilibrium Thermodynamics and Lifetime of Physical Systems
V. V. Ryazanov, S. G. Shpyrko
To describe the nonequilibrium states of a system we introduce a new thermodynamic parameter - the lifetime of a system. The statistical distributions which can be obtained out of…

Nonlinear effects in E Jahn-Teller model: Variational approach with excited phonon states and mode correlations
Eva Majernikova, S. Shpyrko
Interplay of nonlinear and quantum effects in the ground state of the E Jahn-Teller model was investigated by the {\it variational approach and exact numerical s…
