Kekulé Superconductivity in Twisted Magic Angle Bilayer Graphene

This paper proposes a microscopic theory identifying an intra-valley, finite-momentum Kekulé pair-density wave (PDW) as the mechanism for unconventional superconductivity in twisted magic-angle bilayer graphene, a state that naturally explains key experimental signatures including nematic order, triplet pairing, and specific spectral evolution.

Effects of high-order Van Hove singularities on exciton and trion energy dispersions

This paper investigates how high-order Van Hove singularities in the valence band of two-dimensional semiconductors dramatically enhance the density of states and reshape the energy dispersions of excitons and trions, offering a pathway to engineer specific bound states for novel optical applications in materials like monolayer $\alpha$ -SnAs.

Nonlinear Anisotropy in Phase-Tuned Wide-Gap Halides

This study demonstrates that silver iodide (AgI) thin films exhibit distinct, phase-dependent nonlinear optical anisotropies, with zincblende and wurtzite phases showing different second harmonic generation symmetries and effective susceptibilities, thereby establishing AgI as a versatile platform for investigating phase-tuned nonlinearity in wide-gap halides.

Optimizing spin-based terahertz emission from magnetic heterostructures

This paper presents a systematic theoretical analysis of spin-based terahertz emission from magnetic heterostructures using a superdiffusive spin-transport model to establish optimization guidelines regarding layer thickness, interface properties, and excitation protocols, ultimately revealing trade-offs between bandwidth and efficiency while proposing a double-pulse trilayer protocol for enhanced broadband emission.

Grain-boundary-mediated kinetic arrest in graphite-to-diamond transformation

Using large-scale molecular dynamics simulations, this study reveals that precursor grain structure governs the graphite-to-diamond transformation by decoupling nucleation from propagation, where grain boundaries facilitate local nucleation but arrest growth at mismatched interfaces, thereby stabilizing kinetically trapped mixed sp²-sp³ states and establishing structural heterogeneity as a critical control parameter alongside pressure and temperature.

High density two-component glasses of organic semiconductors prepared by physical vapor deposition

This study utilizes spectroscopic ellipsometry to demonstrate that co-vapor deposited NPD and TPD organic semiconductor glasses form high-density, thermally stable materials whose properties are governed by substrate temperature and surface equilibration mechanisms, with phase transformations initiating at the free surface and propagating into the bulk.
