Testing Nonclassicality and Non-Gaussianity in Phase Space
Nonclassicality Non-Gaussianity Phase Space
font style='font-size:12px;'>
2016/1/22
We theoretically propose and experimentally demonstrate a nonclassicality test of a single-mode field in phase space, which has an analogy with the nonlocality test proposed by Banaszek and Wódkiewicz...
Effect of Ion Dynamics on the Evolution of Electron Phase-space Holes
Ion dynamics Electron holes Transverse instability Magnetized plasma

2013/10/3
The evolution of two-dimensional (2D) electron phase-space holes (electron holes) has been previously investigated with electrostatic Particle-in-Cell (PIC) simulations, which neglect ion dynamics. Th...
Phase space parametrization of rain: the inadequacy of the gamma distribution
Phase space parametrization of rain the inadequacy of gamma distribution
font style='font-size:12px;'>
2012/11/23
We show that the Gamma distribution is not an adequate fit for the probability density function of drop diameters using the Kolmogorov-Smirnov goodness of fit test. We propose a different parametrizat...

2011/1/18
The concepts of phase space Feynman integrals in White Noise Analysis are established.As an example the harmonic oscillator is treated. The approach perfectly reproduces the right physics. I.e. , solu...
Structure in phase space associated with spiral and bar density waves in an N-body galactic disk

2011/1/11
An N-body simulation of a Galactic disk is used to study the stellar phase space distribution or velocity distributions in different local neighborhoods. Pattern speeds identified in Fourier spectrogr...
Exact phase space functional for two-body systems
Exact phase space two-body systems
font style='font-size:12px;'>
2010/12/27
The determination of the two-body density functional from its one-body density is achieved for Moshinsky's harmonium model, using a phase-space formulation, thereby resolving its phase dilemma. The c...

2010/12/27
Forty-five years after the point de d\'epart [1] of density functional theory, its applications in chemistry and the study of electronic structures keep steadily growing. However, the precise form of...
Static isolated horizons: SU(2) invariant phase space, quantization, and black hole entropy

2010/12/20
We study the classical field theoretical formulation of static generic isolated horizons in a man-ifestly SU(2) invariant formulation. We show that the usual classical description requires revision in...
