Disorder-tuned crossing of monopole and conventional pairing instabilities in multi-Weyl semimetals

This paper demonstrates that non-magnetic impurity scattering in multi-Weyl semimetals can tune the leading pairing instability from a topologically nontrivial monopole channel to a conventional s-wave channel, establishing a specific criterion for this crossover based on the interplay between disorder strength and the relative critical temperatures of the competing pairing states.

Spatial and temporal resolution issues in turbulent wall-shear measurements

This paper characterizes the spatio-temporal filtering effects of capacitive MEMS sensors on wall shear stress measurements in high-Reynolds-number boundary layers by combining experimental iso-Reynolds-number analysis with synthetic filtering of DNS data, ultimately establishing a validated framework to correct for high-frequency spectral attenuation caused by finite sensor resolution.

SCAPS-1D Modeling and Recombination Loss Analysis of All-Inorganic CsPbI₂Br/CuI Indoor Perovskite Solar Cells for Autonomous IoT Harvesters

This study utilizes SCAPS-1D modeling to demonstrate that optimizing interfacial band alignment and passivating defects in all-inorganic CsPbI₂Br/CuI perovskite solar cells can boost indoor photovoltaic efficiency from 19.46% to 32.56%, identifying interfacial non-radiative recombination as the primary loss mechanism and confirming the device's viability for powering autonomous IoT sensors.

The Quark-Lepton Cross-Sector Bridge from State Equilibrium Condition

This paper proposes a parameter-free Left-Right Symmetric framework where distinct (B − L) assignments generate sector-dependent stiffness factors that enforce a universal equilibrium condition, successfully predicting the observed quark-lepton mixing asymmetry, CP-violating phases, and the specific deviation of the quark-lepton complementarity sum from 45° without adjustable parameters.

Spatial mode selection at THz frequency in a periodically poled lithium niobate waveguide

This paper demonstrates a compact and flexible method for selectively generating specific terahertz spatial modes in a periodically poled lithium niobate waveguide by adjusting the relative delay between chirped optical excitation pulses, achieving efficient, narrowband multi-cycle THz waveforms without altering the waveguide structure.
