This tutorial review presents a comprehensive theoretical and experimental framework for identifying, quantifying, and correcting polarization-induced artifacts in single-object circular dichroism spectroscopy, thereby enabling reliable measurements of supramolecular chirality in heterogeneous molecular aggregates.
This paper demonstrates that in two-band noncentrosymmetric superconducting rings, sufficiently strong inversion symmetry breaking induces a magneto-electric coupling that stabilizes interband phase solitons as true ground states with field-determined chirality, replacing the metastable states found in centrosymmetric materials.
This study demonstrates that complex nanoscale geometries can fundamentally alter a system's thermodynamic response, specifically enabling the manipulation of apparent heat capacity through structural design rather than chemical changes.
This paper demonstrates that an electrostatic spherical shell with anisotropic dielectric properties can host an exceptional point and undergo a non-Hermitian phase transition solely through spatial hyperbolicity, causing the electric field to oscillate and create hotspots without requiring gain, loss, or non-reciprocity.
This paper develops a theoretical model for hydrodynamic magnetotransport in two-dimensional electron systems with arbitrary edge roughness, predicting that specific non-monotonic behaviors in Hall resistance—such as high-field saturation and magnetic-field-induced minima—serve as distinct experimental signatures of the viscous flow regime and allow for the quantification of edge roughness.
This paper demonstrates that discrete screw symmetry in long molecules significantly enhances spin preservation beyond standard timescales through quasi-momentum spin separation, offering a theoretical explanation for chirality-induced spin selectivity and proposing a magnetoresistance signature in spin-valve setups as an experimental verification.
This study reports the successful synthesis of high-quality bilayer kagome ferromagnet CoSn thin films via molecular beam epitaxy, revealing robust room-temperature ferromagnetism and a large intrinsic anomalous Hall effect driven by Berry curvature hotspots near the Fermi level.
This paper establishes the dynamical phase diagram of a driven rotor in a quantum solvent, revealing a dissipative rotational sound barrier where the molecule resonantly emits bath excitations and undergoes strong angular momentum exchange, thereby enabling the study of ultrafast rotating impurities beyond equilibrium angulon theory.
This study demonstrates a giant bulk photovoltaic effect in MoS2/Ta2NiSe5 van der Waals heterostructures driven by interfacial symmetry breaking and spontaneous charge transfer, achieving a record zero-bias photocurrent density of 247 A/cm² through a minimalist orthogonal device geometry that enables the clear separation and optimization of competing photophysical mechanisms.
This paper presents a systematic terahertz spectroscopy study combined with semianalytical modeling to explain the intrinsic gyrotropic optical response and giant anomalous Hall effect in the magnetic Weyl semimetal CoSnS as arising from the momentum-space separation of its Weyl nodes, while quantitatively constraining the material's physical parameters.
