This paper presents a nanoscale surface analysis of high entropy alloys using nano-IR spectroscopy to characterize their optical properties and potential oxide formation, while proposing an extension to full 3D polarization analysis for mapping local orientational dependencies.
This paper proposes an efficient numerical method using adaptive mesh refinement to compute the -space second Chern number in four-dimensional topological systems, which outperforms existing approaches by achieving higher accuracy with fewer computations, lower memory usage, and robustness near topological phase transitions.
This study combines semi-analytic Boltzmann-Bloch modeling with experimental validation to demonstrate that the transient absorption bleach intensity in gold nanoparticles does not always linearly correlate with electron temperature and is significantly influenced by lattice heating.
This paper investigates the dynamics of massless Dirac fermions on curved surfaces with localized axial symmetry, demonstrating through numerical analysis that Gaussian and volcano-like bumps induce a linear discrete energy spectrum and enhanced probability density near the curvature while allowing free wave behavior asymptotically.
This paper demonstrates that a fully atomistic classical electrodynamic model, which couples intraband charge transport and interband polarization, quantitatively reproduces chiroptical spectra across the quantum-to-classical regime, thereby establishing a unified electrodynamic origin for plasmonic chirality and enabling the rational design of chiral plasmonic nanostructures.
This paper reports the generation of highly indistinguishable, single photons at the telecom C-band with a 2.5 GHz clock rate and strong multiphoton suppression by coherently driving the biexciton transition of a semiconductor quantum dot embedded in a microcavity with asymmetric Purcell enhancement.
This paper presents a self-powered, filterless, on-chip full-Stokes polarimeter based on a single-layer/few-layer MoS2 homojunction that utilizes the circular photogalvanic effect and intrinsic optical anisotropy to detect all four Stokes parameters at zero bias within the 650–690 nm wavelength range, offering a compact and low-loss alternative to traditional metasurface-based devices.
This paper theoretically proposes a rapid adiabatic passage-based super-resolution microscopy scheme for quantum dots that utilizes structured, chirped, and time-delayed beams to suppress diffraction rings and achieve high-resolution imaging, particularly under conditions where exciton-phonon decoupling preserves image quality at higher pulse areas.
This study utilizes density functional theory and non-equilibrium Green function methods to demonstrate that introducing monoatomic boron vacancies in hexagonal boron nitride layers sandwiching a three-atom-thick graphene layer creates a van der Waals magnetic tunnel junction capable of achieving a record-high tunneling magnetoresistance ratio of approximately 400% due to spin-dependent transmission differences between parallel and antiparallel magnetic configurations.
This study experimentally maps the topological band structure of three-terminal graphene Josephson junctions using tunnelling spectroscopy and magnetic flux control, revealing a transition from gapped to gapless Andreev bound states that mimics nodal-line semimetals and demonstrates the potential for engineering higher-dimensional topological phases.
