Abstract

In many-body nonlinear systems with sufficient anharmonicity, a special kind of lattice vibrations, namely, Localized Anharmonic Vibrations (LAVs) can be excited either thermally or by external triggering, in which the amplitude of atomic oscillations greatly exceeds that of harmonic oscillations (phonons) that determine the system temperature. Coherency and persistence of LAVs may have drastic effect on quantum tunneling due to correlation effects discovered by Schrodinger and Robertson in 1930. These effects have been applied to the tunneling problem by a number of authors, who demonstrated a giant increase of sub-barrier transparency during the increase of the correlation coefficient at a special high-frequency periodic action on quantum system. Recently, it has been proposed that discrete breathers (a sub-class of LAVs arising in periodic systems) present the most natural and efficient way to produce correlation effects in regular crystals due to time-periodic modulation of the potential well (or the Coulomb barrier) width and hence to act as breather nano-colliders catalyzing low energy nuclear reactions (LENR) in solids. It has been shown that the tunneling probability for the D-D fusion under electrolysis of heavy water increases enormously with increasing number of oscillations resulting in the fusion rates comparable with those observed experimentally. In the present paper, we discuss possible ways of engineering the nuclear-active environment (NAE) and catalyzing LENR in NAE based on the LAV concept. We propose some practical ways of catalyzing LENR that are based on a special electro-magnetic treatment or electron irradiation, which trigger LAVs in crystals and clusters.
