Phonon-assisted tunneling in Jahn-Teller Ee impurity centers in crystals
V. Hizhnyakov
Tunnel transitions between various distorted states of impurity centers in crystals with the Ee Jahn-Teller effect are considered, taking into account changes in the dyna…
Enhancement of long-wave vibronic interaction and quantum diffusion in liquids
Vladimir Hizhnyakov, Aleksander Shelkan
The zero-phonon type hoping motion of defects in the solid and liquid phases, causing quantum diffusion, is considered. It was found that due to the previously discovered significa…
Rate theory of acceleration of the defect annealing driven by discrete breathers
V. I. Dubinko, J. F. R. Archilla, V. Hizhnyakov +1
Novel mechanisms of defect annealing in solids are discussed, which are based on the large amplitude anharmonic lattice vibrations, a.k.a. intrinsic localized modes or discrete bre…
Theory and MD simulations of intrinsic localized modes and defect formation in solids
V. Hizhnyakov, M. Haas, A. Shelkan +1
MD simulations of recoil processes following the scattering of X-rays or neutrons have been performed in ionic crystals and metals. At small energies (<10 eV) the recoil can induce…
Experimental observation of moving intrinsic localized modes in germanium
J. F. R. Archilla, S. M. M. Coelho, F. D. Auret +3
Deep level transient spectroscopy shows that defects created by alpha irradiation of germanium are annealed by low energy plasma ions up to a depth of several thousand lattice unit…
Pressure dependence of two-level systems in disordered atomic chain
A. Shelkan, V. Hizhnyakov
The dependence of two-level systems in disordered atomic chain on pressure, both positive and negative was studied numerically. The disorder was produced through the use of interat…
