Thermoluminescence properties, radiation-induced defects, and glow curve deconvolution in Mn2+-doped Na–Al phosphate glasses

This study demonstrates that Mn²⁺-doped Na–Al phosphate glasses exhibit linear thermoluminescence dose response and act as effective TL emission centers, with glow curve deconvolution revealing six distinct trap types with activation energies ranging from 0.61 to 1.1 eV responsible for the radiation-induced emission.

Critical non-thermal fixed point and the dynamical condensation phase transition

This paper utilizes a non-perturbative quantum kinetic framework to demonstrate that the equilibrium Bose-Einstein condensation threshold acts as a dynamical critical point, organizing far-from-equilibrium dynamics into distinct universality classes characterized by different non-equilibrium attractors and scaling laws depending on the quench depth.

Reaching the thermodynamic limit of periodic CCSD cohesive energies and band gaps

This paper presents a scalable distributed-memory implementation of periodic CCSD theory that enables high-density Brillouin zone sampling to reliably extrapolate cohesive energies and band gaps to the thermodynamic limit, providing definitive benchmark values for eight semiconductors and insulators with errors of approximately 0.1 eV for cohesive energies and 0.4 eV for band gaps compared to experiment.

Stochastic Hamiltonian Modulation of Energy-Marked Quantum States: An Ensemble-Based Numerical Assessment

This study demonstrates through ensemble-based numerical simulations that a stochastic Hamiltonian modulation model, originally proposed as an oracle-free search algorithm, fails to produce statistically significant marked-state amplification at weak perturbation strengths and instead functions as a configuration-dependent exploratory framework for noise-assisted quantum dynamics.

Inverse freeform design of two-dimensional reflectors for a finite-source problem using an integro-differential formulation

This paper presents an inverse freeform design method for two-dimensional reflectors that addresses finite-source problems by formulating the task as an optimal transport problem, deriving a linking integral equation, and solving for convex reflector profiles through surface parametrization and loss minimization.

Structure–Transport–Performance Relationships in Directionally Solidified (Ga,In)Sb– CrSb Eutectic Composites: Anisotropic Charge and Heat Transport for Thermoelectric Energy Conversion

This study demonstrates that directionally solidified (Ga,In)Sb–CrSb eutectic composites achieve enhanced thermoelectric performance through anisotropic microstructures that simultaneously boost electrical conductivity along aligned CrSb rods and suppress thermal conductivity perpendicular to them via interface scattering.

Emergent unconventional superconductivity in an aged α-Sn thin film

This study reports the discovery of intrinsic, unconventional type-II Ising superconductivity in an aged α-Sn thin film, where aging-induced elemental diffusion and electronic reconstruction trigger a quantum phase transition that creates a new Fermi-surface band with linear dispersion, establishing α-Sn as a promising platform for topological superconductivity.
