This paper reports the discovery of the quasi-one-dimensional material CsCrS, which uniquely exhibits the simultaneous coexistence of the mutually exclusive charge-density-wave and Tomonaga-Luttinger liquid states due to subtle cesium vacancies that shift the Fermi level into a linearly dispersive band without disrupting the CDW order.
This study combines operando scanning electron microscopy with frequency-modulated Kelvin probe force microscopy to achieve the first work-function-resolved imaging of CO oxidation on platinum surfaces, revealing that chemical wave propagation is driven by relaxation-type oscillations characterized by rapid oxygen coverage onset and gradual CO-state relaxation.
This paper proposes a driven-dissipative polariton realization of artificial spin ice where circular polarization acts as Ising spins and a lossy vertex enforces ice rules, enabling the creation, transport, and direct imaging of emergent magnetic monopoles and Dirac strings in a controllable nonequilibrium photonic platform.
This study reveals that the stability and migration of the central disclination in fivefold-twinned gold nanoparticles are governed by a geometry-controlled competition between axis centering and detwinning, where concave morphologies promote symmetry restoration while shallow convex geometries trigger rapid structural relaxation.
This study employs a material-specific microscopic approach to reveal how exchange, saturation, and dipole-dipole interactions govern polariton-polariton dynamics in MoS cavities, highlighting asymmetric energy shifts and electrically tunable anti-crossing closures that are crucial for advancing ultra-compact polaritonic circuitry.
This study elucidates the dual mechanistic role of oxygen in MoS2 chemical vapor deposition, demonstrating that it simultaneously enhances precursor evaporation while modulating reaction kinetics through sulfur oxide formation, thereby enabling a controlled dosing strategy for scalable, high-quality monolayer synthesis.
This paper demonstrates that introducing momentum-conserving resonant tunneling in sliding ferroelectric tunnel junctions with lattice-aligned graphene electrodes overcomes the intrinsic weak polarization limitation, achieving a high tunneling electroresistance ratio of 225.65% alongside ultrafast, low-energy, and robust switching performance suitable for next-generation nonvolatile memory.
This study investigates re-entrant supercurrents in planar InAs-Al Josephson junctions under high in-plane magnetic fields, demonstrating that while some features align with topological or 0- transitions, they can also be fully explained by disorder-induced mode interference without invoking Zeeman splitting or topology.
This paper presents a theoretical framework for the polarized photoluminescence of triplet excitons in semiconductor nanocrystals, modeling random fine structure via Gaussian orthogonal ensemble exchange and hyperfine interactions to calculate luminescence intensity and optical orientation/alignment, including their modulation by external longitudinal magnetic fields.
This paper uncovers the microscopic mechanism of slow dynamics in one-dimensional quasiperiodic many-body localized systems, identifying quantum amplitude modulation of single-particle hoppings as the cause of structured growth in number entropy and quasiparticle width, thereby supporting the thermodynamic stability of the MBL phase.
