In this work we study the correlated Stokes and anti-Stokes Raman scattering process, called here SaS. The SaS, proposed by Klyshko in 1977 [1], is an effect where the same phonon participates in the Stokes and anti-Stokes scattering processes. The Feynman diagrams of Figure 1 show the Stokes (S), the anti-Stokes (as) and the SaS processes. The SaS process has not been considered in current tre...
PURPOSE To evaluate the correlation between Armaly's structural systems with Brusini's functional staging in glaucomatous patients. METHODS Seventy-eight eyes of forty-two patients with primary open-angle glaucoma underwent visual field testing with the Humphrey Field Analyzer II (program SITA 24-2) and optic disc evaluation with the 78D Volk lens by two independent observers. Optic disc was ...
The phase stability and equilibria of carbon dioxide is investigated from 125 -- 325K 1 10,000 atm using extensive molecular dynamics (MD) simulations the Two-Phase Thermodynamics (2PT) method. We devise a direct approach for calculating diagrams in general, by considering separate chemical potentials isolated at specific points on P-T diagram. unique ability 2PT to accurately efficiently appro...
In this paper, the phononic and thermal properties of tungsten disulfide have been studied. The aim of this study was to investigate the phonon and thermal properties such as heat capacity and enthalpy. The calculations are performed within the framework of density functional theory by pseudo-potential methood and by Quantum Espresso computational package and their exchange-correlation function...
In this paper, we propose two spectral cyclic MUSIC DOA estimation algorithms for wideband cyclostationary signals: the wideband spectral cyclic conjugate MUSIC (WSCCM) algorithm and the extended wideband spectral cyclic MUSIC (EWSCM) algorithm. The proposed algorithms can be applied to estimate the spectral cyclic conjugate correlation matrix and the extended spectral cyclic correlation matrix...
Our aim is to put the partially successful analytic noncovariant approaches to Coulomb gauge QCD on a firm and systematic basis. To this end, we develop a generating functional approach to the equal-time correlation functions. In fact, such a functional is given in terms of the vacuum wave functional, however, in a perturbative expansion of the equal-time correlation functions, the vacuum wave ...
Abstract. The Griffiths inequalities for Ising spin-glass models with Gaussian randomness of non-vanishing mean are proved using properties of the Gaussian distribution and gauge symmetry of the system. These inequalities imply that correlation functions are non-negative and monotonic along the Nishimori line in the phase diagram. From this result, the existence of thermodynamic limit for corre...
We determine the quantum phase diagram of the Hubbard chain with electron-hole symmetric correlated hopping at 1/2and 1/4-filling using geometric concepts and continuum limit field theory. The long distance behavior of various correlation functions show a very rich phase diagram with several insulating, metallic, and superconducting phases, which might be relevant to (TMTSF)2X compounds. The cl...
