As an important means of contactless manipulation of targets, optical force has significant application prospects in areas such as light sail propulsion and orbital intervention of space debris. Precise measurement of the optical force generated by spatial targets in complex optical fields is crucial for establishing their spatial dynamics model. The torsion balance can be used to measure the optical torque. We use a 5 μm tungsten fiber to build a torsion balance system to measure the extremely weak optical torque less than 1×10-15 Nm, which can help to establish an accurate model of the interaction between objects and optical forces. At the same time, it provides experimental data for the study of spacecraft orbit control and light sail navigation. © COPYRIGHT SPIE. Downloading of the abstract is permitted for personal use only.

Catenary metasurface has been widely used in fields such as wild-Angle imaging, spectral detection, and broadband absorbers, due to its advantages of high efficiency and broadband. In our previous studies, perfect wavefront control of catenary metasurface is achieved via field-driven optimization (FDO). However, the proposed method focuses solely on the performance of catenary metasurfaces at a specific wavelength. Here, considering the broadband and multifunctional of the catenary and catenary-like metasurfaces, multi-objectives FDO is proposed. With 30 iterations, the average diffraction efficiency of the catenary metasurface increases to ∼96% at the wavelength of 9-13 μm. In addition, considering the functionality, the catenary and catenary-like metasurfaces are optimized with a pair of orthogonal polarized light incidences. The optimization process preserves the chiral nature of the catenary metasurface. After 30 iterations, the diffraction efficiency of the catenary metasurface is improved from 96.4% to 99.2%. For catenary-like metasurfaces, the diffraction efficiencies exceed 90% for both left-handed and right-handed elliptically polarized light incidences. Our work provides a methodology for designing multifunctional complex continuous metasurfaces, which may further promote catenary optics. © COPYRIGHT SPIE.

Non-reciprocal devices are essential in many field that require unidirectional wave transmission, such as communications, sensor technology and quantum computing. However, most existing devices are constrained by factors including power supply, external magnetic field, efficiency, and bandwidth. We demonstrated an all-passive, broadband and high efficient nonreciprocal metasurface based on vanadium dioxide (VO2). The electromagnetic thermal coupling simulation results show that when the incident light power density is 40-55 kW/cm2, the transmittance is 90% in one direction and nearly 20% in the other direction. Moreover, benefiting from the non-resonant structure of the metasurface, the device can be used at a broadband wavelength of 7-12 μm. Thus, the demonstrated device has the advantages of broadband and high efficiency, offering a simple but effective scheme of all-passive unidirectional devices. © COPYRIGHT SPIE.

With orbital angular momentum, tightly focused vortex beams can impose optical torque on particles through momentum transfer. In this paper, based on the Richards-Wolf vector diffraction theory, we examine the forces and moments exerted on Mie particles by a tightly focused beam, including the impact of the beam's intensity distribution and the topological charge (TC) number on particle trapping stability. Numerical calculations are conducted to assess the effects of corresponding parameters on the characteristics of the optical radiation force and the tight focusing properties. Our results show that the direction of the particle's rotation is determined by the sign of the TC numbers and that there is a direct relationship between the magnitude of the induced torque and the TCs. Furthermore, the stability of particle control can be improved by OAM beams with small TCs. These results have potential applications in light capture, optical storage, and optical imaging. © COPYRIGHT SPIE. Downloading of the abstract is permitted for personal use only.

Quantum spin liquids (QSLs) represent a unique quantum disordered state of matter that hosts long-range quantum entanglement and fractional excitations. However, structural disorder resulting from site mixing between different types of ions usually arises in real QSL candidates, which is considered to be an obstacle to gaining insight into the intrinsic physics. Here, we have synthesized two new rare-earth compounds, Rb3Yb(VO4)2 and Cs3Yb(VO4)2. X-ray diffractions reveal a perfect triangular-lattice structure with no detectable disorder. Magnetic susceptibility measurements do not capture any phase transition or spin freezing down to 1.8 K. A fit to low-temperature data indicates dominant antiferromagnetic interactions with a Curie-Weiss temperature of −1.40 and −0.43 K for Rb3Yb(VO4)2 and Cs3Yb(VO4)2, respectively. Specific-heat results show no sign of long-range magnetic order down to ∼0.1K either, but only a Schottky anomaly that is continuously mediated by the external magnetic fields. Additionally, inelastic neutron scattering is employed to detect low-energy spin excitations in Rb3Yb(VO4)2. The absence of magnetic excitation signals as well as static magnetic order down to 97 mK aligns with the results from magnetic susceptibility and specific heat. Collectively, these findings point to a quantum disordered ground state with persistent spin dynamics, reminiscent of QSL behaviors. Our work provides a promising platform for further exploration of quantum magnetism in this new disorder-free system.

Nonreciprocal transmission based on nonlinear optical materials has attracted considerable attention for eliminating the need for complex and bulky external bias systems and shows great potential for high-intensity laser protection. Strongly resonant structures are commonly used to achieve lower laser operating power and higher efficiency. However, this approach typically compromises other critical performance metrics, such as protection power range, maximum operating power, bandwidth, and angular range. Here, a novel strategy is proposed using weakly resonant structures to realize nonreciprocity while preserving high performance across these metrics. This achievement stems from the large out-of-plane refractive index asymmetry in the Si/VO2 catenary structure, enabling robust nonreciprocal transmission with high efficiency across a broad bandwidth (8–11.5 µm) and angular range (>75°) theoretically. This design also shows a higher operating power ceiling and extends the existing tunable nonreciprocal range by an order of magnitude. Experiments validate the tunable nonreciprocal range at 10.6 µm wavelength. Protection capabilities are significantly enhanced through wavefront modulation, offering rapid and effective protection from below the phase transition to above the damage threshold. This work presents a novel paradigm for robust nonreciprocal metasurfaces, with considerable potential for applications in remote sensing, environmental monitoring, biomedicine, and industrial manufacturing. © 2025 Wiley-VCH GmbH.

Sodium-metal batteries are the most promising low-cost and high-energy-density new energy storage technology. However, the sodium-metal anode has poor reversibility, which can be optimized by constructing the robust solid electrolyte interphase (SEI). Here, a concept of dual-weak-interaction electrolyte (DWIE) is demonstrated, its double-layer solvation structure is composed of weakly solvated tetrahydrofuran as the inner layer, and dipole interaction are introduced in the outer layer by dibutyl ether. This double-layer solvation structure dominated by contact ion pairs and aggregates can promote to deriving of inorganic-rich SEI film, resulting in smooth and dendrite-free sodium-metal deposition. By adjusting the molecular configuration of dibutyl ether to diisobutyl ether, the dipole interaction is further enhanced, resulting in stronger weakly solvating effect. Thus, the Na||Cu cells using the optimized DWIE achieved a high Coulombic efficiency of 99.22%, surpassing most electrolyte design strategies. Meanwhile, at 5C, the Na3V2(PO4)3 (NVP)||Na cell achieves stable cycling exceeding 3000 cycles. Even under rigorous conditions of ≈8.8 mg cm−2 NVP loading and 50 µm thickness Na, the full cell can achieve a long cycling lifespan of 217 cycles. The pioneering concept paves the way for crafting readily achievable, cost-effective, and eco-friendly electrolytes tailored for SMBs, and offers potential applications in other battery systems. © 2025 Wiley-VCH GmbH.
