Quantum information scrambling (QI-scrambling) is a pivotal area of inquiry within the study of quantum many-body systems. This research derives mathematical upper and lower bounds for the scrambling rate by applying the Maligranda inequality. Our re

To optimize the entanglement detection, we formulate the metrologically operational entanglement condition in quantum Fisher information(QFI) by maximizing the QFI on the measurement orbit. Specifically, we consider two classes of typical local obser

The inclusive production of pseudoscalar heavy quarkoniua ($\eta_c,~\eta_b$ and $B_c$) via photon-photon fusion in heavy ion ultraperipheral collision (UPC) are calculated to QCD next-to-leading order in the framework of non-relativistic QCD (NRQCD).

The intermediate-mass-ratio inspirals (IMRIs) may be surrounded by dark matter (DM) minispikes. The dynamical friction from these DM minispike structures can affect the dynamics and the gravitational wave (GW) emission of the IMRIs. We analyze the ef

Based on the factorization framework of nonrelativistic quantum chromodynamics, we study the associated $J/\psi+c+\bar{c}$ photoproduction process at next-to-leading order in $\alpha_s$ and leading order in the velocity expansion. The total cross sec

For the first time, we have introduced the Pyramid Constellation of Gravitational Wave Observatory (PCGO) for GW polarization detection. The PCGO is composed of four identical spacecrafts (S/Cs). The laser telescopes and their pointing structures are

Sky locating massive black hole binaries (MBHBs) from the foreground of double white dwarf (DWD) is essential for space-based gravitational wave (GW) detection. In an orbit period of the space crafts, there is an optimal orbital position of the GW de

Recently, ATLAS and CMS collaborations jointly announced the first evidence of the rare Higgs boson decay channel $H\to Z\gamma$, with a ratio of $2.2\pm 0.7$ times overshooting the leading order standard model (SM) prediction. In order to face this

We propose in this work a practical approach, by virtue of correlation matrices of the generic observables, to study the long lasting tough issue of quantum separability. Some general separability conditions are set up through constructing a measurem

We investigate the hyperon semileptonic decays within the framework of QCD sum rules. The flavor $ SU(3) $ symmetry breaking effects are analyzed via the relevant form factors and corresponding branching fractions. Employing the $ z $-series paramete
