Formation of correlated states and optimization of nuclear reactions for lowenergy particles at nonresonant lowfrequency modulation of a potential well
Abstract
A method for the formation of correlated coherent states of lowenergy particles in a parabolic potential well owing to the fullscale lowfrequency modulation ω(t) = ω{sub 0}sinΩt of the parameters of this well has been considered. It has been shown that such a modulation in the absence of a stochastic force acting on a particle results in the fast formation of correlated coherent states and in an increase in the correlation coefficient and transparency of the potential barrier to the limiting values vertical bar r(t) vertical bar {sub max} → 1 and D → 1. The presence of the stochastic force significantly affects the evolution of correlated coherent states, decreasing the rate of an increase in the correlation coefficient vertical bar r(t) vertical bar {sub max} (at Ω ≤ 10{sup −4}ω{sub 0}) and limiting it at the level vertical bar r(∞) vertical bar {sub max} < 1 (at Ω = (0.001–0.1)ω{sub 0}); vertical bar r(∞) vertical bar {sub max} increases with a decrease in the frequency of modulation and decreases with an increase in the intensity of the stochastic force. It has been shown that, at a realistic relation between the parameters, lowfrequency modulation can ensure such vertical bar rmore »

We consider prerequisites and investigate some optimal methods for the formation of a correlated coherent state of interacting particles in nonstationary systems. We study the influence of the degree of particle correlation on the probability of their passage through the Coulomb barrier for the realization of nuclear reactions at low energies. For such processes, the tunneling probability and, accordingly, the probability of nuclear reactions can grow by many orders of magnitude (in particular, the barrier transparency increases from D{sub r=0} AlmostEqualTo 10{sup 42} for an uncorrelated state to D{sub r} ={sub 0.98} AlmostEqualTo 0.1 at a correlation coefficient vertical barmore »

The formation of correlated states and the increase in barrier transparency at a low particle energy in nonstationary systems with damping and fluctuations
We consider peculiarities in the formation of a coherent correlated state (CCS) of a particle in a periodically modulated harmonic oscillator with damping for various types of stochastic perturbation. It is shown that in the absence of stochastic perturbation, an optimal relation exists between the damping parameter (damping coefficient) and the modulation depth, for which the 'extrinsic' characteristics of the oscillator (amplitudes of 'classical' oscillation and the momentum of a particle) remain unchanged, while the correlation coefficient rapidly increases from r = 0 to r{sub max} AlmostEqualTo 1; this corresponds to a completely correlated coherent state. Under nonoptimal conditions, themore » 
NONRESONANT INTERACTION OF CHARGED ENERGETIC PARTICLES WITH LOWFREQUENCY NONCOMPRESSIVE TURBULENCE: NUMERICAL SIMULATION
A new method for simulating the threedimensional dynamics of charged energetic particles in very broadband noncompressive magnetic turbulence is introduced. All scales within the primary inertial range of the turbulence observed in the solar wind near 1 AU are now included for the independent computations of both the particle dynamics and the turbulent magnetic field lines (MFLs). While previous theories of resonant particle pitchangle (PA) scattering and transport in interplanetary magnetic fields had favored interpreting the observed depletions in the electron PA distributions (PADs) around 90 DegreeSign PA as evidence of poor scattering at low PA cosines, the computed particlemore »
