Validity and Limits of Low Order Hybridization Expansion Approaches for Multi-Orbital Systems

By using the decoupled orbital limit as a reference, this study reveals that low-order hybridization expansion methods (NCA and OCA) fail in multi-orbital systems because the accuracy is dictated by the least correlated orbital, whose properties are erroneously transferred to strongly correlated orbitals via spurious coupling, thereby suppressing key features like the Kondo resonance.

Voltage-Tunable Nonequilibrium Dispersion Interactions

This paper develops a nonequilibrium Green's function theory demonstrating that applied bias voltage can significantly enhance attractive dispersion interactions between nanostructures or even induce repulsion through population inversion, thereby generalizing the equilibrium London picture to open quantum systems.

Generation of heat pulses in mesoscopic conductors using light fields

This paper proposes a method to generate controllable, charge-neutral heat pulses in mesoscopic conductors by modulating the temperature of an electronic reservoir via light field interactions, thereby establishing a pathway for on-demand caloritronics and time-resolved heat transport studies.

Dynamical universality in a driven quantum fluid of light

This study demonstrates dynamical universality in a driven quantum fluid of light by experimentally verifying that the relaxation time and correlation length of exciton-polaritons below the condensation threshold obey a universal scaling relation with a dynamical exponent of approximately 2, indicating diffusive dynamics of a non-conserved order parameter.

Strong enhancement of Er3+ emission at room temperature in Si3N4 metasurfaces

This paper reports a significant (~18-fold) enhancement of room-temperature Er3+ photoluminescence in Si3N4 metasurfaces via Mie-type resonances and the Purcell effect, demonstrating a robust, CMOS-compatible pathway for efficient active light sources.

Injection of orbital angular momentum into transition metals from first-principles

This paper uses first-principles quantum mechanical scattering calculations to demonstrate that nonequilibrium orbital currents in transition metals decay within a few atomic layers and partially convert into spin currents, challenging the prevailing interpretation of experimental results that suggest a much longer decay length comparable to the spin-flip diffusion length.
