Generation and Propagation of a Hermite-Gaussian Correlated Schell-Model LG_0l Beam

Applied Sciences, 2019
A partially coherent beam under the combined action of a Hermite-Gaussian correlated function and vortex phase, named the HGCSMLG0l beam has been explored both theoretically and experimentally.

The Off-forward Quark-Quark Correlation Function [PDF]

, 2006
The properties of the non-forward quark-quark correlation function are examined. We derive constraints on the correlation function from the transformation properties of the fundamental fields of QCD occurring in its definition.

Simulation and Experiment of Substation Grounding Resistance Measurement Based on Pseudorandom Signal

Sensors, 2022
The grounding resistance of a substation is an important parameter that should be designed within a reasonable range to prevent operational accidents from damaging electrical equipment due to overvoltage and ensure the safe operation of an electrical ...

Correlation Function of Galaxy Groups

, 2000
We use the Updated Zwicky Catalog of galaxies (Falco et al. 1999) to generate a catalog of groups, by means of a friend-of-friend algorithm. The correlation length of the total sample is well fitted with a power law $ \xi(r)=(r/r_0)^\gamma $ with ...

Random surface correlation functions [PDF]

Communications in Mathematical Physics, 1984
Truncated pair functions for free random surface models and Bernoulli ensembles are examined. In both cases, the pair function is shown to obey Ornstein-Zernike scaling whenever various correlation lengths of the system satisfy a nonperturbative criterion.

Correlation function of dyonic strings

, 2011
We investigate the two- and three-point correlation functions of the dyonic magnon and spike, which correspond to the solitonic string moving in the Poincare AdS and three-dimensional sphere. We show that the coupling between two dyonic magnons or spikes

Dusty Plasma Correlation Function Experiment

, 2003
Dust particles immersed within a plasma environment, such as those in protostellar clouds, planetary rings or cometary environments, will acquire an electric charge.

Effects of fracture parameters and roughness on heat‐flow coupling in rock masses with two‐dimensional fracture networks

Energy Science & Engineering, 2021
Discrete fracture network (DFN) is an effective means of describing the coupling of heat flow in an underground fractured rock mass. In this paper, an improved DFN is proposed by introducing the correlation function of fracture trace length and aperture,
