Transition from Population to Coherence-dominated Non-diffusive Thermal Transport

This paper presents a Wigner Transport Equation-based framework to model non-diffusive thermal transport driven by both phonon populations and coherences, predicting significant size-dependent thermal conductivity deviations in low-conductivity materials like CsPbBr $_3$ and La $_2$ Zr $_2$ O $_7$ at experimentally accessible length scales.

Device-area selection of memristive transport regimes in epitaxial $Hf_{0.5}Zr_{0.5}O_{2}$ -based ferroelectric devices

This study shows that epitaxial Hf $_{0.5}$ Zr $_{0.5}$ O $_2$ -based ferroelectric memristive devices exhibit coexisting area-dependent tunneling and localized-conduction regimes, with a statistical crossover at approximately $10^3~\mu\mathrm{m}^2$ that correlates with the onset of ferroelectric wake-up and oxygen-vacancy redistribution.

Electronic Signature of Melting Onset in Polycrystalline Copper at Extreme Conditions

Using single-shot terahertz spectroscopy and molecular dynamics simulations, researchers demonstrate that the onset of melting in polycrystalline copper produces a distinct electronic signature—a transient increase in conductivity caused by the suppression of grain-boundary scattering—thereby revealing a close coupling between ionic disorder and electronic relaxation in nonequilibrium laser-driven matter.

Experimental quantification of electronic symmetry breaking through orbital hybridization phase

This paper proposes and validates an experimental framework that quantifies electronic symmetry breaking, specifically electronic chirality, by determining orbital hybridization phases from synchrotron X-ray diffraction data, thereby establishing a predictive descriptor for chiral physical responses like circular dichroism.

Charge Density Wave Driven Topological Phase Transition in Vortices

This paper proposes a theoretical framework demonstrating that the phase of a stripe charge density wave can control the topological state of a magnetic vortex, particularly through an inversion-symmetry-breaking mechanism that induces a robust transition by enabling spin-triplet pairing.

Disambiguating electrical detection of magnetization dynamics in magnetic insulators

This paper establishes a framework to disambiguate the competing contributions of spin pumping and spin-torque ferromagnetic resonance in electrical detection of magnetization dynamics within magnetic insulators, demonstrating that signal sign and magnitude are governed by spin-wave profiles, magnetic damping, and device geometry rather than magnon chirality alone.
