Plasmonic nanoantennas provide unique opportunities for precise control of light–matter coupling in surface-enhanced infrared absorption(SEIRA)spectroscopy,but most of the resonant systems realized so far suffer from the obstacles of low sensitivity,narrow bandwidth,and asymmetric Fano resonance ***,we demonstrated an overcoupled resonator with a high plasmon-molecule coupling coefficient(μ)(OC-Hμresonator)by precisely controlling the radiation loss channel,the resonator-oscillator coupling channel,and the frequency detuning *** observed a strong dependence of the sensing performance on the coupling state,and demonstrated that OC-Hμresonator has excellent sensing properties of ultra-sensitive(7.25%nm^(−1)),ultra-broadband(3–10μm),and immune asymmetric Fano *** characteristics represent a breakthrough in SEIRA technology and lay the foundation for specific recognition of biomolecules,trace detection,and protein secondary structure analysis using a single array(array size is 100×100μm^(2)).In addition,with the assistance of machine learning,mixture classification,concentration prediction and spectral reconstruction were achieved with the highest accuracy of 100%.Finally,we demonstrated the potential of OC-Hμresonator for SARS-CoV-2 *** findings will promote the wider application of SEIRA technology,while providing new ideas for other enhanced spectroscopy technologies,quantum photonics and studying light–matter interactions.

Dissipative preparation of Bell states with parallel quantum Zeno dynamics

引用

Science China(Physics,Mechanics & Astronomy) 2019年第11期62卷 57-62页

作者： Chong Yang dongxiao li XiaoQiang Shao Center for Quantum Sciences and School of Physics Northeast Normal UniversityChangchun 130024China Center for Advanced Optoelectronic Functional Materials Research and Key Laboratory for UV Light-Emitting Materialsand Technology of Ministry of EducationNortheast Normal UniversityChangchun 130024China

We propose a new mechanism, parallel quantum Zeno dynamics, to dissipatively prepare all Bell entangled states of the twoqubit system in the context of cavity quantum electrodynamics. This mechanism can provide two transition channels between ground states and two different dark states simultaneously, which efficiently speeds up the stabilization of the entanglement and suppresses the adverse influence of surrounding environments. In addition, there is no need for the initialization of quantum states and the Clauser-Horne-Shimony-Holt inequality can be violated in a finite temperature bath. The experimental feasibility is also studied by the state-of-the-art technique and a high fidelity about 99% can be achieved.

Hepatocellular carcinoma(HCC)is a highly heterogeneous tumor,with dynamic equilibrium and complex interplay between its intricate tumor nature and ambient tumor immune microenvironment(TIME).1 Elegant research has indicated that cancer stem cells,a small subset of neoplastic cells confined within dedicated niches,display stem cell-like properties and interact with cells in TIME,thereby imparting an indelible impact on stemness regulation,tumor heterogeneity,and cancer cell plasticity.2 Previous taxonomies solely from the perspective of stemness or TIME may introduce some degree of bias in the comprehension of HCC carcinogenesis,3,4 and thus it is of paramount importance to systematically consider tumor stemness and TIME as a whole to truly portray the biological landscape of HCC.

"地位授予"是大众传播媒介重要的社会功能,获得媒介授予的"地位"对社会组织意味着可获得公共关注及在社会场域中行动的合法性。通过报道中"媒介身份"的建构,大众传媒能够完成对社会组织的地位授予。本文以一个进入中国多年的国际环保组织为个案,分析其留痕于国内媒体报道中的"媒体身份",以从经验考察中透视我国媒体对社会组织的"地位授予"功能。本文显示:"国际"身份既是国际性非政府组织获得媒体身份的有利因素,也构成了一种障碍。"国家-社会"关系的变化直接影响着媒体对其媒体身份的建构。在不同的媒体类型、报道议题中,国际非政府组织的媒体身份会被选择性地呈现。我国媒体对国际非政府组织"媒体身份"的建构具有不稳定性和策略性,这也显示出国际非政府组织与我国媒体之间关系的不稳定。这种状态呈现了中西方媒体对社会组织"地位授予"功能的差异性和本土性。
