Decorrelation of total mass via energy∗

چکیده
The main result of this small note is a quantified version of the assertion that if u and v solve two nonlinear stochastic heat equations, and if the mutual energy between the initial states of the two stochastic PDEs is small, then the total masses of the two systems are nearly uncorrelated for a very long time. One of the consequences of this fact is that a stochastic heat equation with regular coefficients is a finite system if and only if the initial state is integrable.

Higgs production plus two jets at hadron colliders
In this talk we present a calculation of Higgs production via gluon fusion in association with two jets, including the full top-quark mass dependence, and compare it to the large top-mass limit. We find that the large top-mass limit is a good approximation as long as the Higgs mass is smaller than the top quark pair mass, and the jet transverse energies are smaller than the top mass. In additio...
متن کاملDiffusion in an Expanding Plasma using AdS/CFT
We consider the diffusion of a non-relativistic heavy quark of fixed mass M , in a one-dimensionally expanding and strongly coupled plasma using the AdS/CFT duality. The Green’s function constructed around a static string embedded in a background with a moving horizon, is identified with the noise correlation function in a Langevin approach. The (electric) noise decorrelation is of order 1/T (τ...
متن کاملSimulation and modeling of hydrogen production from glucose biomass model compound via hydro-thermal gasification
Glucose is a 6-carbon carbohydrate compound present in plants and the ingredient for hemicellulose which makes up 30% of plants’ total mass. The current study uses glucose as reactant and evaluates hydrogen generation at different temperatures and different amounts of input flow of glucose – water mixture. Hydrothermal gasification method is used for hydrogen generation in an open system with c...
متن کاملSpectrally Condensed Fluid Turbulence and L-H Transitions in Plasma∗)
Recent experimental and theoretical studies of two-dimensional (2D) turbulence reveal that spectrally condensed turbulence which is a system of coupled large-scale coherent flow and broadband turbulence, is similar to plasma turbulence near the L-H transition threshold. Large condensate vortices fed via the turbulent inverse energy cascade, can control both the level of the broadband turbulence...
متن کاملDecorrelation estimates for random discrete schrodinger operators in dimension one and applications to spectral statistics
The purpose of the present work is to establish decorrelation estimates for some random discrete Schrödinger operator in dimension one. We prove that the Minami estimates are consequences of the Wegner estimates and Localization. We also prove decorrelation estimates at distinct energies for the random hopping model and Schrödinger operators with alloy-type potentials. These results are used to...
