This paper reformulates spatial structure optimization as a constrained topological free-energy gradient theory within an admissible phase space, introducing complex physical objects and a double-closure requirement to ensure that hard-valid structures evolve toward energy minimization while preserving admissibility.
This study demonstrates that rhombohedral hexalayer graphene serves as a multi-knob platform where carrier density, displacement field, and out-of-plane magnetic field can be tuned to switch between all four spin-valley isospin flavors, establishing a programmable quartet of chiral superconducting states derived from distinct quarter-metal parent phases.
This study demonstrates that undoped and Fe-doped CdTe nanostructures exhibit n-type conductivity, morphology-dependent optical emissions ranging from violet to green, and enhanced spin-electron behavior at low and room temperatures, making them promising candidates for optoelectronic devices and semiconductor quantum bits.
This paper introduces self-selected phase-matched second harmonic generation as a rapid, non-contact all-optical technique for characterizing refractive-index dispersion in birefringent nonlinear materials, demonstrating its effectiveness in inspecting stoichiometry, temperature gradients, and composition inhomogeneities in lithium niobate-based crystals.
This study demonstrates that a high magnetic field accelerates the lengthwise growth of proeutectoid ferrite while inhibiting its thickness growth in a Fe–0.4 C alloy by increasing the interfacial carbon concentration in austenite, thereby altering the diffusion-controlled transformation kinetics.
This study demonstrates that the choice of impact restitution model significantly alters the global dynamics, stability, and bifurcation characteristics of harmonically excited rocking blocks, with these discrepancies being most pronounced for slender blocks and converging as slenderness increases.
This paper outlines the goals of the SPES_MED project (2025–2027) at INFN-LNL, which aims to produce medical radionuclides using both direct activation and ISOL techniques, while presenting initial results from its first year on nuclear cross-section measurements, production, and modeling.
This paper proposes a route to study monitored many-body dynamics in multimode bosonic systems using circuit quantum electrodynamics, demonstrating that while generic gate sets exhibit conventional measurement-induced phase transitions, a special class of beam-splitter circuits displays a critical-like high-measurement regime with linear purification scaling, all of which are observable with near-term hardware.
This study presents ion-confined perovskite solar cells utilizing a 2D polyaramid nanofilm to suppress ion migration, achieving exceptional thermal durability for space applications and a champion power conversion efficiency of 26.43% through KI doping-induced charge regulation.
This paper investigates a coupled chemo-mechanical-diffusion problem where an elastic solid transforms into a viscoelastic material via a reaction front, analyzing how the competition between chemical affinity, volume expansion-induced stresses, and stress relaxation governs front propagation kinetics and identifies conditions for front blocking and quasi-equilibrium regimes.
