Abstract Robust boundary states epitomize how deep physics can give rise to concrete experimental signatures with technological promise. Of late, much attention has focused on two distinct mechanisms for robustness—topological protection, as well the non-Hermitian skin effect. In this work, we report realizations of hybrid higher-order skin-topological effect, in which effect selectively acts only topological modes, not bulk modes. Our experiments, are performed specially designed...
Recently, a new family of symmetry-protected higher-order topological insulators has been proposed and was shown to host lower-dimensional boundary states. However, with the existence strong disorder in bulk, crystal symmetry is broken, associated corner states are disappeared. It well known that emergence robust edge quantized transport can be induced by adding sufficient disorders into topologically trivial insulator, so-called Anderson insulator. The question whether also cause phase....
Recent theoretical studies have extended the Berry phase framework to account for higher electric multipole moments; quadrupole and octupole topological phases been proposed. Although two-dimensional quantized insulators demonstrated experimentally, not previously observed experimentally. Here we report on experimental realization of a classical analog insulator in circuit system. Three-dimensional topolectrical circuits realizing such are constructed We observe states protected by topology...
It is very attractive to explore topological physics beyond three-dimensional space. This work experimentally demonstrates the realization of a classical analog higher order/dimensional phases in electric circuits. Multiple robust corner states have been observed. These result from nontrivial hexadecapole moment and may potential applications field signal processing with multiple channels. The authors expect that experimental access circuits can provide valuable reference for investigating...
Multibranched gold nanoparticles (M-AuNPs) can serve as photothermal agents for near-infrared (NIR) therapy (PTT) of cancer, but a major shortcoming is that they tend to strongly scatter NIR light, causing significant reduction in absorption. This work addresses this issue, based on theoretical simulations and experimental determinations, enhance the absorption reduce scattering these materials by screening their structural parameters. Our finite-difference time-domain predict M-AuNPs with...
Moir\'e superlattices in the twisted bilayer graphene provide an unprecedented platform to investigate a wide range of exotic quantum phenomena. Recently, twist degree freedom has been introduced into various classical wave systems, giving rise new ideas for control. The question is whether twistronics and moir\'e physics can be extended electronics with potential applications twist-enabled signal processing. Here, we demonstrate both theory experiment that lots fascinating engineered using...
Hyperspectral LiDAR (HSL) has been utilised as an efficacious technique in objects classification and recognition based on its synchronously obtaining spectral spatial information. However, the information obtained by most of developed HSL was visible near-infrared range (VNIR, 400–1000 nm). Whereas a longer wavelength showed more useful for detection, such detecting vegetation water content. This paper proposed tested eight-channel prototype covering to even short-wavelength infrared...
Abstract Relativistic quantum mechanics has been developed for nearly a century to characterize the high-energy physics in domain, and various intriguing phenomena without low-energy counterparts have revealed. Recently, with discovery of Dirac cone graphene, materials their classical analogies provide second approach exhibit relativistic wave equation, making large amounts theoretical predications become reality lab. Here, we experimentally demonstrate third way get into physics. Based on...
Hyperspectral Light Detection And Ranging (Hyperspectral LiDAR), a recently developed technique, combines the advantages of LiDAR and hyperspectral imaging has been attractive for many applications. Supercontinuum laser (SC laser), rapidly developing technique offers suitable broadband source makes Lidar become an installation from theory. In this paper, recent research progressing are reviewed. The researched in theory, prototype system, instrument, application experiment. However, pulse...
Hyperspectral LiDAR (HSL) possesses the advantages of and hyperspectral detection, detects ranging spectrum information synchronously, by one HSL system. The data fusion is also avoided. At present, range reported HSLs usually covers only 500 nm-1000 nm (from visual (VIS) to near infrared (NIR) band). However, there requirement extend short wave (SWIR) band, which often contains more useful spectral information. In this paper, a covering from VIS SWIR reported. HSL, echoes are divided into...

Optical phase with continuously distributed values is always expected to exhibit higher efficiency in the diffraction dominated operation. However, noisy scattering systems, this assertion does not hold. We found that optimized optical distribution forming focus behind media tends a binary configuration. show direct corollary of Shannon theorem when applied process. The holds advantage speeding up optimization processing, which might make it possible image through dynamic such as biological images.
This article explores the increasing convergence of tourism industry with other sectors, emphasizing an evaluation path and its effects on residents. 392 residents in Macau were analyzed. The results presented that positively impacts but negatively affects residents’ environmental perceptions. Environmental perception resident attitudes, while has not significantly impacted attitudes. attitudes by full mediator perceptions, where perceptions have a negative impact positive influence....
