In this paper, we propose a numerical approach to simulate the degree of coherence (DOC) of a partially coherent beam (PCB) with a Schell-model correlator in any transverse plane during propagation.

Geometric interpretation of the three-dimensional coherence matrix for nonparaxial polarization [PDF]
The three-dimensional coherence matrix is interpreted by emphasizing its invariance with respect to spatial rotations. Under these transformations, it naturally decomposes into a real symmetric positive definite matrix, interpreted as the moment of ...

A method for estimating coherence of molecular mechanisms in major human disease and traits
Background Phenotypes such as height and intelligence, are thought to be a product of the collective effects of multiple phenotype-associated genes and interactions among their protein products.

Low-Coherence Interferometric Imaging: Solution of the One-Dimensional Inverse Scattering Problem [PDF]
Optical coherence tomography (OCT) is a non-invasive imaging technique based on the use of light sources exhibiting a low degree of coherence. Low coherence interferometric microscopes have been successful in producing internal images of thin pieces of ...

It is known that a twisted Gaussian Schell-model (TGSM) beam with elliptical Gaussian amplitude will rotate its beam spot upon propagation because of the vortex structure of the transverse energy flux. In this paper, we study a special kind of twisted partially coherent beams named twisted Hermite-Gaussian correlated Schell model (HGCSM) beam whose ...

Research Paper: The Entanglement of Three-mode Spin Coherent States [PDF]
In this study, the detection method of entanglement of 3-mode spin coherence states is investigated. For this purpose, by properly defining the computational codes, these states are mapped to a three qubit quantum state, and then, by using the Mermin ...

Linear Combinations of the Complex Degrees of Coherence
We propose a method for structuring the spatial coherence state of light via mixed linear combinations of N complex degrees of coherence (CDC) and specify the conditions under which such combinations represent a valid CDC.

Enhancing the self-reconstruction ability of the degree of coherence of a light beam via manipulating the cross-phase structure [PDF]
The degree of coherence function of a light beam could be used for optical encryption, robust optical imaging, and other purposes. However, recent works demonstrated that it has a puny self-reconstruction ability that gets worse as the obstacle is ...

Single-shot transverse coherence in seeded and unseeded free-electron lasers: A comparison
The advent of x-ray free-electron lasers (FELs) drastically enhanced the capabilities of several analytical techniques, for which the degree of transverse (spatial) coherence of the source is essential.

Mixedness, Coherence and Entanglement in a Family of Three-Qubit States
We consider a family of states describing three-qubit systems. We derived formulas showing the relations between linear entropy and measures of coherence such as degree of coherence, first- and second-order correlation functions. We show that qubit–qubit
