X-ray transition and K-edge energies in dense finite-temperature plasmas: Challenges of a generalized approach with spectroscopic precision
X. Li, and F. B. Rosmej
The capacity to predict X-ray transition and K-edge energies in dense finite-temperature plasmas with high precision is of primary importance for atomic physics of matter under extreme conditions. The dual characteristics of bound and continuum states in dense matter are modeled by a valence-band-like structure in a ge

Gamma-ray imaging systems are powerful tools in radiographic diagnosis. However, the recorded images suffer from degradations such as noise, blurring, and downsampling, consequently failing to meet high-precision diagnostic requirements. In this paper, we propose a novel single-image super-resolution algorithm to enhan

The effect of drive laser wavelength on the growth of ablative Rayleigh–Taylor instability (ARTI) in inertial confinement fusion (ICF) is studied with two-dimensional numerical simulations. The results show that in the plasma acceleration phase, shorter wavelengths lead to more efficient coupling between the laser and

Signatures of superconductivity near 80 K have recently been discovered in single crystals of La3Ni2O7 under pressure, which makes it a new candidate for high-temperature superconductors dominated by 3d transition elements, following the cuprate and iron-pnictide superconductors. However, there are several critical que

Leading role of satellite interstitial electrons in superconductivity in ternary superlithide Li14CP
Yan Liu, Tian Cui, and Da Li
The discovery of pressure-induced superconducting electrides has sparked a intense wave of interest in novel superconductors. However, opinions vary regarding the relationship between non-nuclear attractors (NNAs) and superconductivity, with two opposing views currently represented by the materials Li6P and Li6C. Here,
