This study demonstrates that a robust nanofabrication protocol restoring atomic-scale purity to epitaxial graphene on SiC enables the emergence of macroscopic excitonic coherence in HMTP overlayers, revealing a Davydov-split vibronic manifold where a dark excitonic branch dominates radiative relaxation via a polaron-mediated pathway.
This paper introduces an all-optical imaging modality that achieves 100-attosecond temporal and 200-nanometer spatial resolution to directly visualize the spatiotemporal evolution and vector electric field lines of light within a widefield transmission microscope, enabling the observation of ultrafast scattering dynamics and pulse broadening in MoTe2 that are inaccessible via standard simulations.
First-principles calculations reveal that monolayer CrSBr exhibits significant thermal anisotropy (with a ratio of approximately 1.8) driven by phonon velocities and lifetimes, which can be further tuned by controlling flake size to suppress long mean free path phonons.
This study demonstrates that bulk single crystals of the triplet superconductor uranium ditelluride (UTe) exhibit an intrinsic, electrically controllable memory effect where magnetic-field-tuned current pulses switch the material between metastable states of distinct critical currents, offering a promising pathway for ultralow-power superconducting memory in cryogenic computing.
This paper proposes a universal criterion for identifying multifractal critical states in disordered quantum systems by demonstrating that they uniquely exhibit dual-space invariance between position and momentum, a property revealed through matching scaling behaviors of the inverse participation ratio that distinguishes them from extended and localized states.
This study demonstrates the fabrication and characterization of an ultrathin subwavelength grating made from epitaxially grown MoSe that supports optical bound states in the continuum and enhances third-harmonic generation efficiency by over three orders of magnitude, paving the way for compact near-infrared photonic devices.
This study establishes BiBr as a second-order topological insulator by experimentally demonstrating the existence of phase-coherent, micrometer-long 1D ballistic hinge modes through the observation of Aharonov-Bohm interference, weak antilocalization, and universal conductance fluctuations.
By systematically varying the resistivity of beta-Tungsten in Py/W bilayers and applying a geometry-correction protocol to harmonic Hall measurements, researchers demonstrated that the Slonczewski-like spin-orbit torque efficiency depends on bulk resistivity while the field-like component remains resistivity-independent, confirming its interfacial origin.
This paper establishes a general theory of light-matter interactions in non-Abelian photonic lattices, revealing chiral photon emission, spin-polarized Landau polaritons, and collective dynamics that bridge non-Abelian gauge fields with quantum optics to enable the synthesis of topological quantum states and control of photon-mediated correlations.
This paper derives a previously overlooked entropic Casimir contribution to the binding potential for 3D short-ranged wetting from a microscopic Landau-Ginzburg-Wilson Hamiltonian, demonstrating that while this term preserves the global surface phase diagram, it fundamentally alters predictions for fluctuation effects at first-order and tricritical wetting transitions.
