This paper presents and experimentally demonstrates two independent optical methods for absolute primary nanothermometry using rare-earth-doped nanoparticles, which determine temperature solely from the internal population dynamics of Stark sublevels without external references, thereby enabling single-ion, wide-range thermal sensing at the nanoscale.
This paper establishes that the intrinsic nonlinear thermal Hall effect in altermagnets is governed by specific symmetry selection rules requiring a nontrivial quantum metric and the simultaneous breaking of mirror and twofold rotational symmetries, a condition naturally met by -wave but not -wave systems due to their distinct orbital hybridization properties.
This study demonstrates that accounting for out-of-plane conductivity in layered materials like PtTe is crucial for accurate spin transport evaluation, as conventional isotropic assumptions significantly overestimate key parameters such as the out-of-plane spin diffusion length and spin Hall conductivity.
Using neutron spectroscopy, researchers directly detected the magnetic signature of chiral phonons in ferrimagnetic FeZnMoO below its Curie temperature, revealing strong magnon-phonon coupling and establishing neutron scattering as a powerful tool for probing the magnetic character of these excitations.
This study provides direct spectroscopic evidence of tunable plasmonic polarons in self-intercalated 1T-TiS2, demonstrating that electron-plasmon coupling creates composite quasiparticles whose energy scales can be controlled by carrier density and temperature, distinct from conventional electron-phonon polarons.
This study predicts that the ferroelectric polarization in multiferroic monolayer CrNBr2 induces a Berry curvature dipole, enabling nonvolatile control of large nonlinear Hall and circular photogalvanic effects for potential applications in nanoelectronic and optoelectronic devices.
This study employs first-principles calculations and cluster dynamics to reveal that hydrogen-induced vacancy stabilization, driven by electronic structure differences such as d-band width and disorder, significantly enhances hydrogen-assisted creep in BCC Fe compared to FCC Fe and Fe-Cr-Ni alloys.
This study demonstrates that Parylene C thin films exhibit an ultralow thermal conductivity of 0.10 W/m-K that can be tuned to 0.18 W/m-K via post-annealing-induced crystallization, establishing the material as a superior insulator for advanced microelectronics packaging.
This paper presents a theoretical investigation into how inter-pulse delay and film thickness influence the laser-induced damage threshold and optical characteristics of thin metallic targets under double femtosecond pulse irradiation, aiming to optimize micromachining protocols for a wide range of industrial metals.
This study introduces a solvent-free, room-temperature remote plasma-assisted vapor deposition (RPAVD-N2) technique to integrate iron(II) phthalocyanine into carbon nanofibers, creating high-performance pseudocapacitive electrodes that achieve significantly enhanced capacitance, energy density, and cycling stability through controlled plasma-induced molecular integration.
This study experimentally validates the robustness of chiral edge states in Chern insulator MnBi2Te4 devices by demonstrating that quantized Hall transport persists even when the edge channel is severed by engineered geometric defects created via AFM nanomachining.
This study demonstrates that hydrostatic pressure induces a divergent response in the layered perovskite (4FPEA)SnBr, where the band edge emission redshifts while the self-trapped exciton emission anomalously blueshifts due to pressure-modified exciton-phonon coupling, a phenomenon absent in its iodide analogue due to differences in lattice rigidity and dielectric screening.
This paper proposes the spin-rotation quantum geometric tensor as a novel probe to experimentally access the intrinsic geometry of persistent spin textures by demonstrating that it generates a unique, direction-independent nonlinear gyrotropic current, thereby overcoming the limitations of conventional geometric measurements in these systems.
This study utilizes a machine-learning-assisted high-throughput density functional theory framework to systematically investigate the stability, electronic structure, and magnetic ground states of 234 MXT MXenes, successfully predicting lattice parameters with high accuracy and classifying their diverse magnetic behaviors across various transition-metal compositions.
Using a novel first-principles approach based on non-collinear KKR Green's functions within time-dependent density functional theory, this study investigates the spin dynamics of MnRh, revealing three linearly dispersing Goldstone modes and characterizing their substantial Landau damping away from the Brillouin zone center.
This paper demonstrates that while parameter-efficient reinforcement learning with verifiable rewards significantly improves a compact language model's performance on beam statics, it primarily induces anisotropic procedural template matching rather than robust, transferable physical reasoning, highlighting the need for structured scaffolding to achieve genuine scientific understanding.
This study demonstrates that ultraclean, coherently strained CaVO thin films exhibit Fermi liquid behavior, quantum oscillations revealing three distinct charge carriers, and a dominant non-saturating linear magnetoresistance, highlighting the complex interplay between multiple carriers and correlations in orthorhombically distorted perovskites.
