Complexity growth and the Krylov-Wigner function

Journal of High Energy Physics
For any state in a D-dimensional Hilbert space with a choice of basis, one can define a discrete version of the Wigner function — a quasi-probability distribution which represents the state on a discrete phase space.

Relation between Quaternion Fourier Transform and Quaternion Wigner-Ville Distribution Associated with Linear Canonical Transform

Journal of Applied Mathematics, 2017
The quaternion Wigner-Ville distribution associated with linear canonical transform (QWVD-LCT) is a nontrivial generalization of the quaternion Wigner-Ville distribution to the linear canonical transform (LCT) domain. In the present paper, we establish a

Applications of the Wigner Distribution Function in Signal Processing

EURASIP Journal on Advances in Signal Processing, 2005
We present a review of the applications of the Wigner distribution function in various areas of signal processing: amplitude and phase retrieval, signal recognition, characterization of arbitrary signals, optical systems and devices, and coupling ...

Level and width statistics of the open many-body systems

EPJ Web of Conferences, 2016
The level and width statistics of the two kinds of the random matrix models coupled to the continuum are analyzed. In the first model, the gaussian orthogonal ensemble with random couplings to the continuum, not only the width statistics deviate from the

Kaon GTMDs in the Dyson–Schwinger equations using contact interaction

European Physical Journal C: Particles and Fields
An array of the kaon twist-two, three, four generalised transverse momentum dependent parton distributions (GTMDs) has been investigated within the framework of covariant and confining Dyson–Schwinger equations using contact interaction.

Quantum Field Theory in the Weyl–Wigner Representation

Universe
The Wigner representation for quantum mechanics of particles is generalized to Bose fields. The standard Hilbert space quantization becomes, via the Weyl transform, a quantization method that consists of adding a Gaussian zeropoint field distribution to ...

Wigner negativity, random matrices and gravity

Journal of High Energy Physics
Given a choice of an ordered, orthonormal basis for a D-dimensional Hilbert space, one can define a discrete version of the Wigner function — a quasi-probability distribution which represents any quantum state as a real, normalized function on a discrete

Wigner Functions

Encyclopedia
Wigner functions are a distribution function on phase space that allow to represent the state of a quantum-mechanical system. They are in many ways similar to classical phase space probability distributions, but can, in contrast to these, be negative.
