Self-Focusing Property of Partially Coherent Beam With Non-Uniform Correlation Structure in Non-Linear Media

open access: yesFrontiers in Physics, 2022
Coherence in a light beam has the potential to serve as a degree of freedom for manipulating the beam. In this work, the self-focusing property of a partially coherent beam with a non-uniform correlation structure propagating in a non-linear medium is ...

Pairing versus quarteting coherence length [PDF]

open access: yesPhysical Review C, 2015
We systematically analyse the coherence length in even-even nuclei. The pairing coherence length in the spin-singlet channel for the effective density dependent delta (DDD) and Gaussian interaction is estimated. We consider in our calculations bound states as well as narrow resonances. It turns out that the pairing gaps given by the DDD interaction are

Experimental test of decoherence theory using electron matter waves

open access: yesNew Journal of Physics, 2018
A controlled decoherence environment is studied experimentally by free electron interaction with semiconducting and metallic plates. The results are compared with physical models based on decoherence theory to investigate the quantum-classical transition.

Formation and Fluctuation-Induced Conductivity of (Tl1-xBix)Sr2CaCu2O7-δ (x = 0.1-0.7) Superconductor

open access: yesInternational Journal of Electrochemical Science, 2016
The (Tl1-xBix)Sr2CaCu2O7-δ (x = 0.1, 0.2, 0.3, 0.4, 0.5,and 0.7) samples were prepared by the solid-state reaction method. The samples were studied by powder X-ray diffraction method, electrical resistance measurements and energy dispersive X-ray ...

A study of the effects of Gaussian distribution of coherence length of source on the diffraction of partial temporal coherence beam from multi slits: Theory and simulation

open access: yesResults in Optics, 2023
First, we have generalized the notion of Franhoufer diffraction of temporal coherent light from a single slit to the case of arbitrary n-slits. The diffraction pattern is investigated for different values of recently (Koushki and Alavi, 2019) introduced ...

Transverse horizontal spatial coherence in shallow water [PDF]

open access: yesMATEC Web of Conferences, 2019
Since the advent of large-aperture array processing, more and more attention has been paid to the sound field correlation, which has fundamental limit to the array gain of spatial coherent signal processing.

In-plane p-wave coherence length in iron-based superconductors

open access: yesResults in Physics, 2020
High-temperature superconductivity in iron-based layered compounds discovered by Hosono group (Kamihara et al. 2006 J. Am. Chem. Soc. 128 10012) is fascinating physical phenomenon which still has many unanswered questions.

Decoherence of Excitons in Multichromophore Systems: Thermal Line Broadening and Destruction of Superradiant Emission [PDF]

open access: yes, 2005
We study the temperature-dependent dephasing rate of excitons in chains of chromophores, accounting for scattering on static disorder as well as acoustic phonons in the host matrix.

Coherent vortex motion in Yba2cu3o7-Z superconducting thin films containing Π-shaped channel for easy vortex motion biased at I ~ IC / Magnetinių sūkurių koherentinio judėjimo YBa2CU3O7-X superlaidžiuosiuose plonuosiuose sluoksniuose su lazeriu suformuotu

open access: yesMokslas: Lietuvos Ateitis, 2012
The current vs. voltage dependences of YBa2Cu3O7-x superconducting microbridges containing laser–written (LW) -shaped channel for easy vortex motion have been investigated in a narrow range of temperatures ranging from 87.3 to 88.6 K that are still ...

Light field analysis for modeling and transmission characteristics of partially coherent light-emitting diodes

open access: yesFrontiers in Physics, 2023
When analyzing the transmission characteristics of LEDs for long-distance lighting and communication applications, the light field is commonly assumed to be fully incoherent. However, in reality, the LED light source emits partially coherent light with a
