Testing Nonclassicality and Non-Gaussianity in Phase Space
Nonclassicality Non-Gaussianity Phase Space
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...
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 derive semi-analytic formulae for the local bispectrum and trispectrum in general two-field inflation and provide a simple geometric recipe for building observationally allowed models with observa...
Galilean symmetry in the effective theory of inflation: new shapes of non-Gaussianity
Galilean symmetry effective theory inflation
2010/12/23
We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory of Inflation, the theory of small perturbations around the inflationary background. This approach allows...
The Gauge-Invariant Bias of Dark Matter Haloes with Primordial non-Gaussianity
The Gauge-Invariant Dark Matter Haloes
2010/12/27
The non-linear evolution of the halo population is followed by solving the continuity equation under the hypothesis that haloes move by the action of gravity. An exact and general formula for the Eule...

of Inflation, the theory of small perturbations around the inflationary background. This approach allows...
We investigate the non-Gaussianity of primordial cosmological perturbations within our recently proposed holographic description of inflationary universes. We derive a holographic formula that determi...
