Near-field Dressing of Thermal Emission

This paper experimentally demonstrates that near-field electromagnetic coupling between two heated microspheres reshapes their far-field thermal emission by inducing a distance-dependent "dressed emissivity," thereby establishing a thermal analogue of the Purcell effect where the surrounding photonic environment renormalizes the radiation properties of the emitters.

Fermion parity of an Andreev molecule probed by nonlocal Josephson effect

This paper demonstrates that the global fermion parity of a delocalized superconducting state in a carbon nanotube-based Andreev molecule can be locally detected through characteristic π\pi-phase shifts in the nonlocal Josephson response, establishing parity as an experimentally accessible degree of freedom in hybrid superconducting circuits.

Electrothermal control of spin-reorientation transition in Co/Fe_3GaTe_2 heterostructures

This study demonstrates reversible electrothermal control of a spin-reorientation transition in Co/Fe₃GaTe₂ heterostructures, where Joule heating modulates the competition between the metallic Co overlayer and the van der Waals magnet to enable heat-assisted, device-level manipulation of magnetic anisotropy.

Sub-microsecond conformational dynamics in an optical nanocavity

This paper presents a fibre-integrated silicon-photonic sensor that overcomes previous speed and noise limitations to enable continuous, label-free, single-shot observation of protein conformational dynamics at sub-microsecond resolution, revealing kinetic details and molecular heterogeneity previously hidden by ensemble averaging.

Disentangling topological and anomalous Hall contributions of skyrmions using Kerr microscopy and thermal transport measurements

This study successfully disentangles the small topological Hall effect from the dominant anomalous Hall effect in Ta/CoFeB/MgO thin films by combining magneto-optical Kerr microscopy with thermal and electrical transport measurements, thereby confirming skyrmion formation and quantifying the topological Hall resistivity at room temperature.

Phase-controlled quasi-bound states in the continuum and thermoelectric enhancement in Majorana-quantum-dot nanostructures

This study demonstrates that phase-controlled symmetry breaking of bound states in the continuum within a Majorana-quantum-dot nanostructure significantly enhances electronic thermoelectric performance, achieving a figure of merit of approximately 0.75 through superconducting-phase tuning and a pronounced violation of the Wiedemann-Franz law.

Excitonic structure in CsPbBr3_3 nanocubes, nanorods and nanoplatelets: the effect of dimensionality

This theoretical study employs a variational effective mass model to demonstrate that quantum and dielectric confinement in CsPbBr3_3 nanocrystals of varying dimensionality (nanocubes, nanorods, and nanoplatelets) primarily enhance exciton binding energies and radiative recombination rates through wavefunction squeezing along strongly confined directions, while revealing that biexciton geometries consistently adopt a distorted tetrahedral shape across all systems.

The Crossover from Ordinary to Higher-Order van Hove Singularity in a Honeycomb System: A Parquet Renormalization Group Analysis

This paper employs parquet renormalization group analysis to investigate the crossover from ordinary to higher-order van Hove singularities in honeycomb systems like bilayer and trilayer graphene, revealing how the merging of Fermi pockets and the resulting changes in density of states drive complex electronic ordering tendencies through the evolution, disappearance, and reemergence of renormalization group fixed points.
