Lensing of the CMB: Non-Gaussian aspects
Physical Review D, 2000 Abstract: We compute the small angle limit of the three‐ and four‐point function of the cosmic microwave background (CMB) temperature induced by the gravitational lensing effect by the large‐scale structure of the universe. We relate the non‐Gaussian aspects presented in this paper with those in our previous studies of the lensing effects.

Metrological detection of entanglement generated by non-Gaussian operations
New Journal of PhysicsEntanglement and non-Gaussianity are physical resources that are essential for a large number of quantum-optics protocols. Non-Gaussian entanglement is indispensable for quantum-computing advantage and outperforms its Gaussian counterparts in a number of

Extended Object Tracking Based on Gaussian Process in Non-Gaussian Noise Environment
Journal of Aerospace Technology and ManagementExtended object tracking (EOT) is a prominent research area in high-resolution radar surveillance, ship tracking, and video tracking. However, EOT algorithms are susceptible to non-Gaussian noise from factors such as sensor performance and ...

Stochastic resonance in asymmetric bistable coupled network systems driven by non-Gaussian noise
四川大学学报. 自然科学版In this paper, we take the dynamic characteristics in an N-dimensional asymmetric bistable coupled network system subject to periodic signal and non-Gaussian noise by virtue of the signal-to-noise ratio (SNR) measures.

The paper studies (non-Gaussian) diffusions classified as either ``hypo-diffusion'' or ``hyper-diffusion'', where the \(\beta\) order moments are of the type \(t^{\beta/\alpha}\), with \(\beta\) and \(\alpha\) belonging to \(\mathbb{R}^*_+\). The authors introduce signed measures corresponding to non-Gaussian diffusions on \(\mathbb{R}\), inspired by ...

Detection of non-Gaussian signals in non-Gaussian noise using the bispectrum
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1990The problem of detecting a non-Gaussian time series in the presence of additive Gaussian or non-Gaussian noise is cast into a classical hypothesis testing framework, using the sample bispectrum as the test statistic. The power of the test is demonstrated as a function of signal-to-noise ratio, the degree of skewness of the signal, and processing ...

LENGTH OF INFLATION AND NON-GAUSSIANITY
International Journal of Modern Physics D, 2011Certain inflation models are shown to have large non-Gaussianity in special cases. Namely, slow-roll inflation models with an effective higher derivative interaction, in which the length of inflation is finite and a scalar-matter-dominated period or power inflation is adopted as pre-inflation, are considered.

The non-Gaussian dynamics of glycerol
Journal of Physics: Condensed Matter, 2011We have combined incoherent quasielastic neutron scattering experiments and atomistic molecular simulations to investigate the microscopic dynamics of glycerol moving away from the hydrodynamic limit. We relate changes in the momentum transfer (Q) dependence of the relaxation time to distinct changes of the single-particle dynamics. Going from small to
