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...
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.
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...
Hanbury Brown-Twiss interferometry and second-order correlations of inflaton quanta
Hanbury Brown-Twiss interferometry second-order correlations of inflaton quanta
2010/12/21
The quantum theory of optical coherence is applied to the scrutiny of the statistical
properties of the relic inflaton quanta. After adapting the description of the quantized scalar
and tensor modes...
Initial correlations in open system's dynamics: The Jaynes-Cummings model
Initial correlations open system's dynamics Jaynes-Cummings model
2010/11/8
Employing the trace distance as a measure for the distinguishability of quantum states, we study the influence of initial correlations on the dynamics of open systems. We concentrate on the Jaynes-Cu...
We discuss a cluster-like 1D system with triplet interaction. We study the topological properties of this system. We find that the degeneracy depends on the topology of the system, and well protected ...
Entangled three-particle states in magnetic field: Periodic correlations and density matrices
quantum entanglement Wigner rotation Lorentz transformation density matrix
2010/3/10
Time evolutions of different types of entangled states of three spin-1/2 particles are studied in the presence of a constant, external magnetic field, which causes the individual spins to precess. Thi...
Broadcast copies reveal the quantumness of correlations
Broadcast copies quantumness of correlations
2010/4/8
We study the quantumness of bipartite correlations by proposing a quantity that combines a measure of total correlations -- mutual information -- with the notion of broadcast copies -- i.e., generally...
Non-classical correlations from dissociation time entanglement
Non-classical correlations dissociation time entanglement
2010/4/8
We discuss a strongly entangled two-particle state of motion that emerges naturally from the double-pulse dissociation of a diatomic molecule. This state, which may be called dissociation-time entangl...

2010/4/8
Group theoretic methods to construct all N-particle singlet states by iterative recursion are presented. These techniques are applied to the quantum correlations of four spin one-half particles in the...

Correlations photon-numbers integrated intensities parametric processes three optical fields
2010/4/8
Two strongly-pumped parametric interactions are simultaneously realized in a single nonlinear crystal in order to generate three strongly correlated optical fields. By combining together the outputs o...

spooky action-at-a-distance quantum correlations: Resolution EPR nonlocality puzzle
2010/10/18
The long-standing puzzle of the nonlocal Einstein-Podolsky-Rosen correlations is resolved. The correct quantum mechanical correlations arise for the case of entangled particles when strict locality is...

Superluminal Hidden Communication as the Underlying Mechanism for Quantum Correlations: Constraining Models
Superluminal Hidden Communication the Underlying Mechanism Quantum Correlations
2010/10/13
Since Bell’s theorem, it is known that quantum correlations cannot be described by local variables (LV) alone: if one does not want to abandon classical mechanisms for correlations, a superluminal for...
