The present paper generalizes the analysis [18, 2] of the correlations for a lattice system of real-valued spins at low temperature. The Gibbs measure is assumed to be generated by a fairly general pair potential (Hamiltonian function). The novelty, as compared to [18, 2], is that the single-site (self-) energies of the spins are not required to have only a single local minimum and no other ext...

Investigations for decay of unstable D-brane and rolling of accelerated D-brane dynamics have revealed that various proposed prescriptions give different result for spectral amplitudes and observables. Here, we study them with particular attention to unitarity and open-closed channel duality. From ab initio derivation in the open string channel, both in Euclidean and Lorentzian worldsheet appro...

We present results on resonance production by the NA49 and CERES collaborations. The measurement of the differential yields and spectral distributions of the K∗(892), Δ(1232), ρ, φ and Λ(1520) resonances from their leptonic and hadronic decay channels at different C.M.S. energies and for various colliding systems allows us to study in-medium modifications of the resonance mass, width and yield ...

Both theory and experiment have suggested that parametric decay instability (PDI) is a possible edge power loss mechanism in ICRF (including HHFW and IBW) heating of tokamak plasmas. In this paper, we consider the extension of previous theoretical models to enable a quantitative evaluation of pump depletion and power loss due to PDI. A set of nonlinear coupled equations for a long-wavelength “d...

Nonlinearities in the drift and diffusion coefficients influence temporal dependence in scalar diffusion models. We study this link using two notions of temporal dependence: β − mixing and ρ − mixing. We show that β − mixing and ρ − mixing with exponential decay are essentially equivalent concepts for scalar diffusions. For stationary diffusions that fail to be ρ−mixing, we show that they are s...

The luminescence spectral and kinetic characteristics of CsPbCl3 nanocrystals, thermally created in a CsCl:Pb single crystal and dispersed in a CsCl matrix, have been studied under excitation by synchrotron radiation in the VUV spectral region (4 to 20 eV). Various components found in the decay kinetics of the 2.98 eV emission have been connected with the direct excitation of the CsPbCl3 lumine...

A fully relativistic/QED theory of particle motion damping by light pressure of an isotropic, in particular relic, radiation yields analytic results for the momentum decay of an electron over entire span of energies in the Universe. Using a Fokker-Planck-like equation, the evolution of initial extremely-high-T electron distribution to low-energy spectral line is analytically obtained for moment...

Low-energy electron emission induced by 1–4 keV Ne4þ ion impact on an Al surface was analyzed. Distinct lines observed near 22 eV are attributed to Auger electrons ejected from doubly excited Ne decaying well above the surface. Spectral structures near 11 eV are primarily associated with the decay of bulk plasmons. After instrumental effort of extending the capability of the spectrometer to mea...

Quantum nonadiabatic molecular dynamics simulations are used to explore the molecular details surrounding photoexcitation of solvated electrons in deuterated water. The results are compared to previous studies in normal water @B. J. Schwartz and P. J. Rossky, J. Chem. Phys. 101, 6902, 6917 ~1994!# to elucidate the nature of the isotope effect on both the solvation and nonadiabatic relaxation dy...
