This paper reports the direct imaging of the Meissner effect and local superfluid stiffness in a rhombohedral graphene superconductor, revealing that superconductivity emerges within a canted spin ferromagnetic phase and exhibits a temperature-dependent stiffness and zero-temperature scaling incompatible with standard BCS theory.
This study demonstrates that hexagonally-packed polystyrene microsphere lattices coated with tunable tantalum pentoxide shells function as scalable dielectric metasurfaces that enhance Rhodamine 6G fluorescence by optimizing the overlap between lattice resonances and emitter bands, with experimental results and multi-scale simulations confirming that shell thickness and emitter placement jointly control the local density of optical states and fluorescence enhancement.
This study investigates electron and heavy hole spin relaxation in indirect band gap (In,Al)As/AlAs quantum dots, revealing that while both carriers exhibit power-law magnetic field scaling, the scaling exponents undergo a dramatic size-dependent transformation from and in 9 nm dots to a unified dependence in 16 nm dots.
This paper demonstrates that altermagnet-superconductor heterostructures host Majorana bound states with a characteristic double-peak spatial profile localized at interfaces due to intrinsic anisotropic hopping, offering a promising route for creating controllable topological qubit networks without external magnetic fields.
This study demonstrates that medium-entropy MXenes, particularly when thermally annealed to convert surface OH groups to O terminations, achieve ultralow friction and superlubricity through enhanced adhesion reduction and suppressed energy dissipation driven by their compositional complexity and increased bending stiffness.
This paper proposes a scalable framework for topological quantum computing using Matryoshka-type Sine-Cosine chains that enable high-dimensional qudit encoding and Y-junction braiding to reduce physical resource overhead while offering partial protection against disorder.
This study demonstrates that photon echo signals generated by excitons in lead halide perovskite nanocrystals exhibit classical behavior with Poissonian statistics and minimal noise, as evidenced by a second-order correlation function of unity and a characteristic function consistent with classical states, despite the system's low signal efficiency.
This paper establishes a self-consistent framework to decode the nonlinear optical responses in 3R-MoS Fabry-Pérot microcavities, revealing that the emission is governed by a frequency-dependent interplay between intrinsic absorption and cavity effects, where weak absorption at harmonic frequencies enables complex modulation by both fundamental and harmonic Fabry-Pérot resonances, whereas strong absorption restricts the response to fundamental-frequency modulation.
This study investigates the orbital magnetic moment and angular momentum of magnons in a Kagome antiferromagnet with negative spin chirality, revealing a quantitative distinction between thermodynamic and wave-packet definitions while demonstrating that their associated Nernst coefficients exhibit similar transport behaviors.
This paper establishes a rigorous theoretical framework for linear viscoelasticity across the sol-gel transition, demonstrating that the continuity of dynamic moduli and their derivatives at the critical gel point necessitates symmetric relaxation dynamics, which unifies scaling laws, imposes a hyper-scaling relation, and reveals a lower bound for the critical relaxation exponent.
