Emergence of non-ergodic multifractal quantum states in geometric fractals
Abstract Eigenstate multifractality, a hallmark of non-interacting disordered metals, features anomalously slow dynamics and is relevant across quantum platforms ranging from measurement-driven systems to superconductivity. Despite extensive work on multifractality in disordered and quasiperiodic…

Determination of coupling state within a spin-torque oscillator using injection locking
Abstract Dynamic interactions between magnetizations enable complex operations in spintronic devices, such as coupled oscillation in spin-torque oscillators (STOs). Here, we report the experimental determination of coupling states in an STO using an analysis method based on injection locking. The…

Self-trapping and skin solitons in two-dimensional non-Hermitian lattices
Abstract Two-dimensional non-Hermitian photonic lattices with asymmetric couplings offer rich possibilities for controlling wave localization, through the emergence of the non-Hermitian skin effect at lattice corners or sides. Yet, how optical nonlinearity modifies these boundary-localization…

Background-free 12C(α, γ) angular distribution measurements with a time projection chamber operating in Gamma beams
Abstract The carbon oxygen ratio (C/O) at the end of stellar helium burning is a crucial nuclear input to stellar evolution theory. Knowledge of the C/O ratio with sufficient accuracy has eluded measurement over the past five decades. It is determined by the rate of oxygen formation in the fusion…

Cavity-driven arbitrary in-plane focusing of phonon polaritons in hBN with deep-subwavelength confinement
Abstract Precise control of phonon-polaritons (PhPs) in planar media is a central challenge for advancing mid-infrared nanophotonics. Here, we demonstrate cavity-driven excitation and shaping of in-plane PhPs in hBN using subwavelength resonators lithographically defined at the Au/SiO2 interface…

A counter-intuitive low entanglement percolation threshold in mixed-state quantum networks
Abstract Understanding entanglement percolation across quantum networks (QNs) has been a persistent challenge. Concurrence percolation theory (ConPT) provides a statistical-physics framework for this, drawing parallels between entanglement measure (concurrence) and classical percolation measure…

Anti-interference circularly polarized LiDAR for ocean detection
Abstract LiDAR has unique advantages for ocean detection. However, its detection range and accuracy are often degraded by variable interference from sunlight and multiply scattered light, which remains a persistent challenge for the quantitative evaluation of ocean-color parameters. This study…

Ultralow radiative heat flux by Anderson localization in quasiperiodic plasmonic chains
Abstract Anderson localization, arising from wave interference in disordered systems, profoundly hinders energy transport, yet its impact on radiative heat flux in many-body thermophotonic systems remains unclear. Here, we demonstrate a three-order-of-magnitude suppression of radiative heat…

Characterizing second-order topological insulators via entanglement topological invariant in two-dimensional systems
Abstract Higher-order topological insulators have attracted significant interest in recent years. However, identifying a universal topological invariant capable of characterizing higher-order topology remains challenging. Here, we propose a entanglement topological invariant designed to…

Attenuation-resilient underwater optical ranging using a spatially petal-like structured beam with tailorable longitudinal intensity
Abstract Scattering in turbid water attenuates optical ranging signals, limiting detectable distance. In this study, we experimentally demonstrate attenuation-resilient underwater optical ranging using a petal-like structured beam such that the detectable ranging distance is increased. The…

Nested interaction network enhances responsiveness in collective behavior
Abstract Survival in dynamic and complex environments requires groups to exhibit a high level of responsiveness to rapidly changing circumstances. Recent studies have shown the role of selective social interactions in driving responsive collective behavior at the individual-level decision making…

Observation and extended Weiss modeling of multi-step type-II spin switching in Mn doped YbFeO3
Abstract Controlling magnetic states with minimal energy input promises faster and more efficient devices. However, achieving programmable, multi-level spin switching in antiferromagnetic materials remains a challenge. Here we observe both conventional and multi-step type-II spin switching, as well…

Granular Ta-Te nanowire superconductivity exceeding the Pauli limit
Abstract Achieving higher upper-critical-field (μ 0 H c2(0)) superconductors is of great interest for both fundamental science and practical applications. While reducing the thickness of two-dimensional (2D) bulk crystals to a few layers significantly enhances μ 0 H c2(0) with accompanied potential…

Optimal coloring and strain-enhanced superconductivity in Li n B n+1C n−1
Abstract Boron-rich lithium borocarbides are promising candidates for phonon-mediated high-temperature superconductors due to their metallic σ-bonding electrons. Here, we use the cluster expansion method to identify energetically stable configurations (colorings) of Li2B3C and Li3B4C2, which are…

Broadband nonlinear microresonator arrays enable topological second harmonic generation
Abstract Integrating efficient second-order (χ (2)) optical nonlinearity into topological integrated photonic systems presents a fundamental challenge: frequency-dependent topological bandgaps inherently impede simultaneous, robust edge states at cross-octave frequencies required for…

One-milligram torsional pendulum toward experiments at the quantum-gravity interface
Abstract Probing the possibility of entanglement generation through gravity offers a path to tackle the question of whether gravitational fields possess a quantum mechanical nature. A potential realization necessitates systems with low-frequency dynamics at an optimal mass scale, for which the…

Assigning entities to teams as a hypergraph discovery problem
Abstract Assigning agents to teams under strict task and effort constraints is crucial in business, science, and engineering, where disruptions can cause significant losses. Current methods do not explore hypergraph-based solutions that explicitly optimize algebraic connectivity under constraints…
