Fractal and FractionalIn order to achieve time–frequency superresolution in comparison to the conventional Wigner distribution (WD), this study generalizes the well-known τ-Wigner distribution (τ-WD) with only one parameter τ to the multiple-parameter matrix-Wigner ...

Distribution and quantification of remotely generated Wigner negativity [PDF]
npj Quantum Information, 2022 Wigner negativity, as a well-known indicator of nonclassicality, plays an essential role in quantum computing and simulation using continuous-variable systems.

Wigner Distribution of Twisted Photons. [PDF]
Physical Review Letters, 2015 We present the first experimental characterization of the azimuthal Wigner distribution of a photon. Our protocol fully characterizes the transverse structure of a photon in conjugate bases of orbital angular momentum (OAM) and azimuthal angle.

The affine Wigner distribution
Applied and Computational Harmonic Analysis, 2022 We examine the affine Wigner distribution from a quantization perspective with an emphasis on the underlying group structure. One of our main results expresses the scalogram as (affine) convolution of affine Wigner distributions. We strive to unite the literature on affine Wigner distributions and we provide the connection to the Mellin transform in a ...

A Wigner Quasiprobability Distribution of Work
Entropy, 2023 In this article, we introduce a quasiprobability distribution of work that is based on the Wigner function. This proposal rests on the idea that the work conducted on an isolated system can be coherently measured by coupling the system to a quantum ...

Wigner distributions for gluons [PDF]
European Physical Journal C: Particles and Fields, 2018 We investigate the gluon Wigner distributions for unpolarized, longitudinally polarized and transversely polarized target state. Instead of a nucleon, we take the target state to be a quark dressed with a gluon at one loop and investigate the gluon ...

Weak values of a quantum observable and the cross-Wigner distribution [PDF]
Phys Lett A, 2011 We study the weak values of a quantum observable from the point of view of the Wigner formalism. The main actor here is the cross-Wigner transform of two functions, which is in disguise the cross-ambiguity function familiar from radar theory and time ...

A simple alternative to the relativistic Breit–Wigner distribution [PDF]
European Physical Journal A, 2021 First, we discuss the conditions under which the non-relativistic and relativistic types of the Breit–Wigner energy distributions are obtained. Then, upon insisting on the correct normalization of the energy distribution, we introduce a Flatté-like ...

Six-dimensional light-front Wigner distribution of hadrons
Physics Letters B, 2022 We propose a six-dimensional light-front Wigner distribution for the complete description of partonic structures of a hadron such as pion and proton, taking advantage of the recently proposed light-front variable z˜ by Miller and Brodsky.

A Novel GNSS Interference Detection Method Based on Smoothed Pseudo-Wigner–Hough Transform
Sensors, 2021 This paper develops novel Global Navigation Satellite System (GNSS) interference detection methods based on the Hough transform. These methods are realized by incorporating the Hough transform into three Time-Frequency distributions: Wigner–Ville ...
