This paper proposes a novel, non-destructive experimental approach using laser-induced ballistic hot electron injection in nanoparticle-on-mirror nanocavities to achieve ultrafast, non-equilibrium modulation of quantum plasmonic properties, supported by a microscopic model and numerical simulations for applications in active plasmonics and nanoscale quantum control.
This paper investigates the topological content of the Zak phase in one-dimensional topological insulators across all Altland-Zirnbauer-Cartan symmetry classes, demonstrating how to construct a -valued invariant from the Zak phase while revealing that quaternionic structures imposed by specific anti-unitary symmetries force this invariant to vanish.
This paper proposes a moiré band theory for twisted square homobilayers, demonstrating that ferroelectricity-driven sliding and interlayer tunneling compete to enable tunable miniband engineering and emergent momentum-space nonsymmorphic symmetries, with CuWS and GeCl identified as promising material realizations.
This paper demonstrates that the spin-orbit coupled - lattice with broken time-reversal symmetry serves as a highly tunable platform for achieving nearly complete spin and valley polarizations in anomalous Hall and Nernst responses, making it a promising candidate for spin-valley caloritronic applications.
This paper proposes a biophotomimetic nonreciprocal quantum battery model inspired by bacterial light-harvesting complexes, utilizing collective quantum states and a unimodal cavity to analyze thermodynamic performance, revealing that while strong coupling enhances energy storage capacity, it compromises power output and alters the optimal system size for ergotropy.
This study investigates magnetotransport in exfoliated nanostructures, revealing that the canted antiferromagnetic state induces an anomalous Hall effect while chiral spin textures give rise to a topological Hall effect, suggesting these phenomena are characteristic features of magnetic 3D topological insulators.
This study demonstrates that low-frequency noise serves as a sensitive probe for microscopic disorder in CVD-grown graphene, revealing that its significantly higher magnitude compared to exfoliated graphene stems from thermally activated dynamics of structural imperfections like grain boundaries and defects.
This paper reports the observation of two-component exciton Bose-Einstein condensates in MoSe2/hBN/WSe2 electron-hole bilayers, demonstrating distinct spin-valley polarized phases and quantum phase transitions up to approximately 1.8 K through magneto-optical spectroscopy.
This study demonstrates that reducing the pulse duration in YBCO bridges from milliseconds to nanoseconds significantly increases the onset current for oxygen electromigration by lowering local temperatures, thereby shifting the process toward an athermal regime with important implications for memristor operation and thermomagnetic stability.
This paper investigates interlayer valley drag in lattice-matched moiré bilayers, demonstrating that umklapp scattering induces a remarkable first-order enhancement of the effect that persists even at low temperatures, and proposes a feasible experimental geometry to detect this phenomenon.
