Geometric Spin-Orbit Coupling Resolves the Contradictory CISS Effect in Chiral Single Molecules

This paper resolves contradictory experimental findings on the chirality-induced spin selectivity (CISS) effect in single molecules by proposing a theoretical framework where geometric spin-orbit coupling and environmental decoherence interact to produce significant spin polarization specifically in an intermediate-decoherence regime, thereby unifying observations across diverse molecular systems.

What Is the Real-Time Atomistic Mechanism Behind Chirality-Induced Spin Selectivity in Donor-Chiral Bridge-Acceptor Molecules?

This paper proposes a quantum dynamical model revealing that geometric spin-orbit coupling, which is significantly stronger than intrinsic coupling in twisted binaphthyl bridges, serves as the intrinsic mechanism driving high spin polarization in photo-excited donor-chiral bridge-acceptor molecules without requiring external fields.

Surface Phase-Field-Crystal-Helfrich model for out-of-plane deformations in thin crystalline sheets with lattice mismatch

This paper presents an extended Surface Phase-Field-Crystal-Helfrich model that incorporates spatially varying lattice spacing to simulate lattice mismatch in thin crystalline sheets, validating the approach against classical theories to demonstrate how localized compressive stresses drive out-of-plane deformations.

Topological characterization of multifold band degeneracies in Altland-Zirnbauer symmetry classes

This paper establishes a topological characterization of generic multifold band degeneracies protected solely by Altland-Zirnbauer symmetries by overcoming the obstruction of enclosing spheres through a novel framework that identifies the stability of these nodes with the linking numbers of intersecting nodal manifolds and their associated spectral gaps.

Magnetic Orbital Hall Effect in Altermagnet RuO2_2

This paper reports experimental evidence of a magnetic orbital Hall effect in the altermagnet RuO2_2, demonstrating that it generates a large, unconventional torque capable of deterministic field-free switching in adjacent ferromagnets, thereby establishing altermagnets as intrinsic sources of orbital currents.

The BPHZL renormalization of a planar quantum electrodynamics up to 2-loops and beyond

This paper demonstrates the ultraviolet and infrared finiteness of a parity-even, massless U(1)×U(1)U(1)\times U(1) quantum electrodynamics in three dimensions up to two loops and beyond by employing the BPHZL renormalization method combined with the Lowenstein-Zimmermann subtraction scheme to address infrared divergences arising from ultraviolet subtractions.

Twist-Angle-Controlled Anomalous Gating in Bilayer Graphene/BN Heterostructures

This study demonstrates that the anomalous gating effects in bilayer graphene/BN heterostructures are governed by the relative angular alignment between the two encapsulating BN layers rather than graphene moiré superlattices, with a specific 15°–45° misalignment range acting as an ON/OFF switch for these phenomena at room temperature.

Binding and spontaneous condensation of excitons in narrow-gap carbon nanotubes

This paper theoretically demonstrates that correlated insulating behavior in all stable narrow-gap carbon nanotubes arises from spontaneous exciton condensation, deriving the scaling laws for exciton binding energy and calculating the fundamental transport gap using a self-consistent, first-principles-validated two-band model.

Universal Thickness-Dependent Absorption in Solids at the Nanoscale: Anomalous Enhancement in the Ultrathin Limit

Through systematic studies of 2D semiconductors, this paper reveals a universal, non-monotonic, and anomalous thickness-dependent absorption behavior in solids at the nanoscale that deviates significantly from the Beer-Lambert law due to electromagnetic interference effects, with implications for a wide range of materials and optoelectronic applications.

3D bulk-resolved gg-wave altermagnetic order parameter in CrSb

This study utilizes high-resolution magnetic quantum oscillation measurements to map the three-dimensional bulk order parameter of CrSb, revealing it to be a prototypical gg-wave altermagnet where the exchange splitting follows the symmetry of the Y4−3\mathcal{Y}_{4}^{-3} real spherical harmonic.
