Wave Packet Propagation in Tilted Weyl Semimetals for Black Hole Analog Systems

This paper demonstrates that spatially varying tilts in Weyl semimetals can create two distinct types of analog black hole horizons—one reflecting and one transmitting wave packets—where zero-momentum packets experience maximal horizon effects and probability loss correlated with their dwell time, establishing these materials as a tunable platform for studying quantum information dynamics near gravitational horizons.

The Origin of Linearly-Polarized Photoluminescence in WS2/WSe2 Moiré superlattices

This study reveals that linearly polarized photoluminescence in WS2/WSe2 moiré superlattices is primarily driven by strain-induced C3 symmetry breaking rather than valley selection rules, establishing strain as a critical parameter for reliable optical control of valley degrees of freedom.

Hierarchical spectral inhomogeneity in photoluminescence of a twisted MoSe2/WSe2 heterobilayer moiré superlattice revealed by hyperspectral mapping

This study utilizes hyperspectral mapping and advanced spectral analysis to reveal that the complex photoluminescence of a twisted MoSe2/WSe2 moiré superlattice is organized by a hierarchical inhomogeneity, where micron-scale contiguous domains coexist with unresolved local spectral manifolds.

Polarized light Raman scattering by an atom near an ultrathin periodically aligned carbon nanotube film

This paper presents a theoretical study demonstrating that an ultrathin film of periodically aligned carbon nanotubes can enhance the Raman scattering cross-section of a nearby two-level atom by up to 10,000 times for both p- and s-polarized light, providing a unified model for quantum near-field enhancement in anisotropic metasurfaces.

Classical Percolation from Quantum Metric in Flat-Band Delocalization

This paper demonstrates that disorder-induced flat-band delocalization in two-dimensional lattices is governed by the real-space quantum metric, exhibiting a critical regime that quantitatively maps to classical bond percolation and establishes linear response conductivity as a direct probe of quantum geometry.

Quantum higher-spin Hall insulators

This paper establishes a theoretical framework for quantum spin Hall insulators with arbitrary spin $J$ , demonstrating that they support $J+\frac{1}{2}$ pairs of helical edge modes with higher-order dispersion and unique non-linear transport properties, which can be realized in ultracold atomic gases.

Photocurrent at oblique illumination and reconstruction of wavefront direction with 2d photodetectors

This paper demonstrates that symmetric metal-2DES junctions generate a zero-bias photocurrent at oblique light incidence due to asymmetric local field absorption, enabling the reconstruction of light incidence direction and angle through photocurrent measurements at variable carrier densities, particularly under 2D plasmon resonance conditions.
