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...
Non-Gaussianity in Two-Field Inflation
Non-Gaussianity Two-Field Inflation

2010/12/27
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...

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...
