Hyperentanglement, which refers to entanglement across more than one degree of freedom (DoF), is a valuable resource in photonic quantum information technology. However, the lack efficient characterization schemes hinders its quantitative study and application potential. Here, we present rapid spatial-polarization hyperentangled biphoton state produced from spontaneous parametric down-conversion. We first demonstrate certification hyperentanglement dimensionality with cumulative acquisition...

Additionally, there is significant bulging characterized higher concentration along line connecting centrals compared to those...

Multinucleon transfer (MNT) reactions have been studied by either the GRAZING model or dinuclear system (DNS) before. MNT in grazing regime described quite well model. The DNS is able to deal with reactions, which happen closer overlapped after contact of two colliding nuclei. Since can both areas and cannot be distinguished view experimental work, it beneficial compare these models clarify mechanism reactions. In this study, reaction has comparing for first time. Reaction systems...
The mechanism of multinucleon transfer (MNT) reactions for producing neutron-rich heavy nuclei around N = 126 is investigated within two different theoretical frameworks: dinuclear system (DNS) model and isospin-dependent quantum molecular dynamics (IQMD) model. effects mass asymmetry relaxation, N=Z equilibration, shell closures on production cross sections are investigated. For the first time, advantages found in MNT based 238U target. We propose with target unknown future.
For decades, supernova remnants (SNRs) have been considered the prime sources of Galactic Cosmic rays (CRs). But whether SNRs can accelerate CR protons to PeV energies and thus dominate flux up knee is currently under intensive theoretical phenomenological debate. The direct test ability operate as PeVatrons be provided by ultrahigh-energy (UHE; $E_\gamma \geq 100$~TeV) $\gamma$-rays. In this context, historical SNR Cassiopeia A (Cas A) one most promising target for UHE observations. This...
The current challenges in High Energy Physics and Cosmology are to build coherent particle physics models describe the phenomenology at colliders laboratory observations universe.

We study a supersymmetric model which incorporates successfully inflation by non-minimal coupling supergravity shows unique collider phenomenology. Motivated experimental data, we set special emphasis on new...
