Study of Optical and Magnetic Properties of Cadmium Telluride Hybrid Nano structures with n-type conductivity for Optoelectronic Device and Quantum Bits Applications

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.

Self-selected phase-matched second harmonic generation in nonlinear optical materials: from phenomenon to applications

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.

Growth kinetics of proeutectoid ferrite isothermal transformation in a Fe–0.4 C (mass%) alloy under a high magnetic field

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.

Hybrid Dynamics of Rocking Blocks Beyond Overturning: Saltation Analysis, Bifurcations, and Stability Characterization

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.

Universal monitored dynamics in multimode bosonic systems

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.

On a coupled problem of chemo-mechanics with a viscoelastic reaction product

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.

Optimized Calibration of Terahertz Polarimetric Imaging Systems With Imperfect Polarizers for Accurate Jones-Matrix Mapping

This paper presents an optimized in situ calibration framework for terahertz polarimetric imaging systems that models imperfect wire-grid polarizers and determines optimal rotation angles to accurately recover sample Jones matrices using a minimal set of measurements, thereby reducing systematic errors and enabling faster, reliable field-deployable imaging.

5D Spatial Brane vs 4D Temporal Quantum Multiverse: A Phenomenological Comparison of Merging-Universe Models in a Modified Friedmann Framework

This paper phenomenologically compares two merging-universe multiverse models—a 5D spatial brane scenario and a 4D temporal quantum multiverse—against multiple cosmological datasets, finding that the latter with foreign dark matter provides a better statistical fit to observations than the former, though both remain preliminary alternatives to the standard ΛCDM model.
