In this paper, we construct orthogonal genuinely multipartite entangled bases in ${({\mathbb{C}}^{3})}^{\ensuremath{\bigotimes}N}$ for $N\ensuremath{\ge}3$, where every state is a one-uniform state. By modifying construction, successfully obtain strongly nonlocal sets and bases, which provide an answer to the problem raised by Halder et al. [Phys. Rev. Lett. 122, 040403 (2019)]. The set constructed contains much fewer quantum states than all known ones. Meanwhile, our results also question...

The past decade has seen a proliferation of topological materials for both insulators and semimetals in electronic systems classical waves. Topological exhibit topologically protected band degeneracies, such as nodal points lines. Dirac line (DNLS), which own four-fold degeneracy, have drawn particular attention. DNLSs been studied but there is no photonic DNLS. Here this work, we provide new mechanism unique to investigate stringent When truncated, the DNLS exhibits double-bowl states...

In this study, we propose and experimentally demonstrate a novel kind of Tamm plasmon topological superlattice (TTS) by engineering photonic crystals (TPCs) belonging to different class topology. Utilizing specifically designed double-layer metasurfaces etching on planar multilayered structures, the TPC that supports bandgap is realized in visible regime. Through coupling interface states existing between TPCs, hybrid plasmon, called supermodes, are obtained can be fully described...

Abstract Quite recently, an unconventional variety of fourfold linear band degeneracy points has been discovered in certain condensed-matter systems. Contrary to standard 3-D Dirac monopoles, these quadruple known as the charge-2 are characterized by nonzero topological charges, which can be exploited delve into hitherto unknown realms physics. Here, we report on experimental realization a point deliberately engineering hybrid states, called super-modes, 1-D optical superlattice system with...

In this paper, we demonstrate a detailed investigation of the high-performance helical long-period fiber grating (HLPFG) near dispersion turning point (DTP) based on thin-cladding (TCF). The LP17 mode DTP can be generated by CO2-laser-inscribed TCF-HLPFG, whose transmissive properties have been studied theoretically and experimentally. With period 140 μm, TCF-HLPFG could obtained at presents high-sensitivity refractive index (RI) sensing ability that maximum RI sensitivity −14962.4 nm/RIU...

Tamm plasmon polaritons (TPPs), localized near the boundary of a dielectric Bragg reflector (DBR) and thin metal film, have attracted much attention for lower ohm loss flexible excitation. However, radiation resulting from direct coupling to surroundings hinders their applications. Here, we propose experimentally demonstrate new type hybrid plasmonic quasi-bound state in continuum (BIC) Tamm-surface polariton system suppress loss. Leveraging scattering periodic array, TPP interacts with...

We study both the temperature and band-gap dependence of first- third-order intraband conductivities a Weyl semimetal (WSM) as well resultant critical field. By semiclassical model we further explore how different chemical potentials, cone separations, field geometries, finite relaxation times affect photoresponse. determine that variation is characterized by separation observe significant thermal enhancement nonlinear response. Universal behaviors linear response have also been observed...

The past decade has witnessed a booming development of topological photonics, which revolutionizes the methodology for controlling behavior light. A gigantic achievement is to engineer robust confined modes localized at interfaces between topologically distinct regions, where optical context can trigger exotic phenomena exclusive photons. Here, we provide an experimentally flexible approach engineering induced interface states in visible regime via unique design complex superlattice formed...

A set of orthogonal states possesses the strongest quantum nonlocality if only a trivial orthogonality-preserving positive operator-valued measure (POVM) can be performed for each bipartition subsystems. This concept originated from strong proposed by Halder $et~al.$ [Phy. Rev. Lett. $\textbf{122}$, 040403 (2019)], which is stronger manifestation based on locally indistinguishability and finds more efficient applications in information hiding. However, demonstrating triviality local...

Language model performance depends on identifying the optimal mixture of data groups to train (e.g., law, code, math). Prior work has proposed a diverse set methods efficiently learn proportions, ranging from fitting regression models over training runs dynamically updating proportions throughout training. Surprisingly, we find that no existing method consistently outperforms simple stratified sampling baseline in terms average test perplexity per group. In this paper, study cause...
