Energy fluctuations, hydrodynamics and local correlations in harmonic systems with bulk noises
Energy fluctuations hydrodynamics local correlations harmonic systems Mathematical Physics
2012/6/12
In this note, I summarise and comment on joint work with C. Bernardin, V. Kannan and J. L. Lebowitz concerning two harmonic systems with bulk noises whose nonequilibrium steady states (NESS) are nearl...
Spatiotemporal correlations of handset-based service usages
Spatiotemporal correlations handset-based service usages Physics and Society
2012/4/20
We study spatiotemporal correlations and temporal inhomogeneities of handset-based service usages by analyzing a dataset collected from 124 users for over 16 months. The dataset consists of detailed i...
Capturing correlations in chaotic diffusion by approximation methods
Capturing correlations chaotic diffusion approximation methods
2011/9/21
Abstract: We investigate three different methods for systematically approximating the diffusion coefficient of a deterministic random walk on the line which contains dynamical correlations that change...
Three dimensional structure from intensity correlations
Three dimensional structure intensity correlations x-ray dilute ensembles
2011/8/5
Abstract: We develop the analysis of x-ray intensity correlations from dilute ensembles of identical particles in a number of ways. First, we show that the 3D particle structure can be determined if t...
Analysis of cross-correlations in electroencephalogram signals as an approach to proactive diagnosis of schizophrenia
Flicker-noise spectroscopy Frequency-phase synchronization Cross-correlations Electroencephalogram signals
2011/8/3
Abstract: We apply flicker-noise spectroscopy (FNS), a time series analysis method operating on structure functions and power spectrum estimates, to study the clinical electroencephalogram (EEG) signa...
On the velocity distribution in homogeneous isotropic turbulence: correlations and deviations from Gaussianity
homogeneous isotropic turbulence deviations Gaussianity Fluid Dynamics
2011/8/1
Abstract: We investigate the single-point probability density function of the velocity in three-dimensional stationary and decaying homogeneous isotropic turbulence. To this end we apply the statistic...
We study the condensed fraction of a harmonically-trapped atomic Bose gas at the critical point predicted by mean-field (MF) theory. The non-zero condensed fraction f0 is induced by critical correlati...
The effect of triangular flow on di-hadron azimuthal correlations in relativistic heavy ion collisions
di-hadron azimuthal correlations relativistic heavy ion collisions
2011/1/5
Using the AMPT model for relativistic heavy ion collisions, we have studied the di-hadron azimuthal angular correlations triggered by emitted jets in Au+Au collisions at center of mass energy psNN = 2...
Effects of Momentum Conservation and Flow on Angular Correlations at RHIC
Effects of Momentum Conservation Flow on Angular Correlations RHIC
2011/1/7
Correlations of azimuthal angles observed at RHIC have gained great attention due to the prospect of identifying uctuations of parity-odd regions in the eld sector of QCD.
Particle number fluctuations and correlations in transfer reactions obtained using the Balian-Veneroni variational principle
Particle number fluctuations correlations transfer reactions obtained Balian-Veneroni variational principle
2011/1/6
The Balian-V´en´eroni (BV) variational principle, which optimizes the evolution of the state ac-cording to the relevant observable in a given variational space, is used at the mean-field l...
Quantum correlations "now and then" are weirder than "here and there"
Quantum correlations Quantum Physics
2010/11/8
Tests such as Bell’s inequality and Hardy’s paradox highlight the differences between local realistic theories and quantum predictions for measurement probabilities and correlations between distant pa...
Deciphering Azimuthal Correlations in Relativistic Heavy-Ion Collisions
Azimuthal Correlations Relativistic Heavy-Ion Collisions
2011/1/6
We discuss various sources of azimuthal correlations in relativistic heavy-ion collisions. The integral measure is applied to quantify the correlations. We rst consider separately the correlations ...

Two nucleon correlations Three- and four-body systems Nuclear spectral function
2011/1/6
Recent BNL and Jlab data provided new evidence on two nucleon corre-lations (2NC) in nuclei. The data confirm the validity of the convolution model, de-scribing the spectral function (SF) of a correla...
