Constraining Non-Standard Interactions with Coherent Elastic Neutrino-Nucleus Scattering at the European Spallation Source

We'll investigate the possibility of constraining non-standard neutrino interactions by high-statistics findings of coherent elastic neutrino scattering at the European Spallation Source. In this case, appropriately selected detector combinations may reduce the degeneracies between two NSI parameters to a small region of the parameter space.

The modified scattering for Dirac equations of scattering-critical nonlinearity

We investigate the Maxwell-Dirac system in 3 dimensions under zero magnetic field in this paper. It becomes a system of Dirac equations with Hartree type nonlinearity with a long-range potential as despite Imposing the Lorenz gauge situation. We use Germain-Masmoudi-Shatah's spacetime reconstruction argument as well as the spinorial null-structure.

Unidirectional scattering with spatial homogeneity using photonic time disorder

Although new research has also shown the effect of broken discrete time-translation synchrony in the case of spatial Anderson localization's temporal analogy, the broad intermediate regime between time order and time uncorrelated disorder has not been investigated. In spatially homogeneous environments, we investigate the opposite design of photonic time disorder in order to achieve optical functionality. We demonstrate engineered time scatterer, which provides unidirectional scattering with controlled scattering amplitudes, by creating the structure factor and order metric from causal Green's functions for time disorder.

Microstructure of die-cast alloys Mg-Zn-Al(-Ca): a study by electron microscopy and small-angle neutron scattering

Comparison of two alloy versions with 0. 3 and 0. 9 wt. % Ca are compared. The microstructure of a magnesium die-cast alloy with 8 wt. % Zn and 5 wt. % Al and 5 wt. % Al and five wt. % Al and five wt. % Al and five wt. % Ca are compared. Small amounts of the stable cubic u3c4 phase Mg 3249 as well as the Al 2 phase were discovered in addition to the I phase at the grain boundaries of the Ca-containing ZA85 alloys. During high-temperature annealing in all alloys tested, regions supersaturated with Al and Zn were found to surround the u03b1-Mg grains and to become 'u03c4 phase precipitation centers during high-temperature annealing.

Plasmon enhanced scattering and fluorescence in amorphous matrix

These improvements are attributed to the surface plasmon resonance effect, in which direct plasmon excitation improves the local field at the nanostructures' surface. Enhanced fluorescence produced by silver nanoparticles may lead to the manufacture of optical displays, laser, and optical memory systems, with Raman amplifiers showing amplification of the Raman signal.

Investigation of the Damage Around a Crack Tip in Metals using Small Angle X-Ray Scattering

Small angle X-ray scattering in an Al-2024 and Al-6013 alloy and a 10 CrMo9 10 reference steel as a result of static deformation was investigated in an Al-2024 and Al-6013 alloy as a result of static deformation. The damage zone's appearance and size are shown by finite element calculations, which show a good correlation.

Robust inverse scattering method to the complex modified Korteweg-de Vries equation with nonzero background condition

Two types of solutions to the focusing challenging modified Korteweg-de Vries equation are developed under nonzero background conditions in this paper, based on Robust's inverse scattering technique. Also, as to this nonzero background condition soliton, the asymptotic analysis is provided as long as t is large, and a comparison between the exact solution and its asymptotic solution is also provided by the numbers.

Coherent States and Particle Scattering in Loop Quantum Gravity

We now have the ability to determine scattering amplitudes using Quantum field theory. Lack of a concrete explanation of particle dispersing processes and a connection to flat space QFT is one of Loop Quantum Gravity's most significant challenges.

Simultaneous Detection of Spin and Orbital Angular Momentum of Light through Scattering from a Single Silver Nanowire

Because of their roles in optical communication systems, micromanipulation, and sub-wavelength position sensing, the spin angular momentum and orbital angular momentum of light have soared in recent years. Both application and basic spin-orbit interaction are two of the most important aspects of research from both application and fundamental spin-orbit interaction. To this end, simultaneous detection of SAM and OAM of light beam is one of the key areas of inquiry from both application and fundamental spin-orbit interaction perspective. The transmitted scattered light intensity distribution in the FP is determined to reconstruct the SAM and OAM state unambiguously by using Fourier plane microscopy.

Comparison of 10 B+ 6 Li and 10 B+ 7 Li elastic scattering: The role of ground state reorientation and breakup

A comparison with existing reports for the 10 B+ 7 Li system at the same time a ten billion B energy event revealed a significant change in the backward angle elastic scattering, with the 10 B+ 6 Li system significantly larger in size. The influence of ten B and seven Li ground state reorientation and breakup couplings on elastic scattering was investigated by a series of coupled channel and coupled discretized continuum channel simulations. The ground state reorientation coupling in 7 Li, although displaying an interesting interference effect with the 10 B ground state reorientation, was also found to have negligible effect on backward angle elastic scattering.
