英格兰足球超级联赛(Premier League,简称“英超”)是英格兰足球总会属下的最高等级职业足球联赛,前身是英格兰足球甲级联赛。英超是“欧洲足球五大联赛”之一,由20支球队组成,由超级联盟负责具体运作,赛季结束后积分榜末三位降入英格兰足球冠军联赛。

英国创造了现代足球的历史,他们在1888年建立了足球联赛并延续发展。英格兰联赛100多年的悠久历史也创下了诸多纪录。而英超联赛创立于1992年2月20日,并于1992/93的赛季成为英格兰的顶级足球联赛。百余年以来英格兰足球联赛分为四个级别的历史正式结束。

2015年8月7日,英足总公布的新赛季规则中进行了一项重要修改,当有球员假摔导致对方被罚下,并经过赛后回放证实为误判后,对方的红牌将被取消,而假摔球员将遭到3场停赛。新规则只用于惩罚那些假摔诈伤导致对方罚下的球员,而利用假摔骗取定位球的情况暂不使用。

▲ 摘要

宇宙射线谱在1 拍电子伏(PeV;1015电子伏),即表明可将粒子加速到超高能量的PeV宇宙射线工厂的存在。定位和识别这些物体将可以找到银河系宇宙射线的起源。

作者报告了从12个超高能γ射线源中检测到530多个光子,能量超过100太电子伏和高达1.4 拍电子伏,统计意义大于7个标准差。

尽管在它们的邻近区域有几个潜在的相似物,包括脉冲星风星云、超新星遗迹和恒星形成区域,但是负责超高能量γ射线的拍电子伏尚未被确定和识别(除了蟹状星云),使得这些极端加速器的起源仍然未知。

▲ Abstract

The extension of the cosmic-ray spectrum beyond 1 petaelectronvolt (PeV; 1015 electronvolts) indicates the existence of the so-called PeVatrons—cosmic-ray factories that accelerate particles to PeV energies.We need to locate and identify such objects to find the origin of Galactic cosmic rays. Here we report the detection of more than 530 photons at energies above 100 teraelectronvolts and up to 1.4 PeV from 12 ultrahigh-energy γ-ray sources with a statistical significance greater than seven standard deviations. Despite having several potential counterparts in their proximity, including pulsar wind nebulae, supernova remnants and star-forming regions, the PeVatrons responsible for the ultrahigh-energy γ-rays have not yet been firmly localized and identified (except for the Crab Nebula), leaving open the origin of these extreme accelerators.

▲ 摘要

未来的量子网络将使遥远地点之间的纠缠分布成为可能,并允许应用于量子通信、量子传感和分布式量子计算。这个网络的核心是在远程互联的量子节点上产生和存储纠缠态的能力。

虽然各种远程物理系统已经成功地纠缠在一起,但没有一个实现包含了网络运行的所有要求。作者报告了两个空间分离的量子节点之间的预示纠缠的演示,其中的纠缠被存储在多模固态量子存储器。

在不同实验室的量子存储器之间的纠缠是通过检测高达1.4千赫兹的电信光子来预示的,并且纠缠被存储在晶体中,预先确定的存储时间高达25微秒。

作者还证明了生成的纠缠对预警路径中的损耗具有鲁棒性,并演示了使用62种时域模式的时间复用操作。作者表示这可以扩展到更长的距离上的纠缠,并为基于固态资源的现场部署、多路复用量子中继器提供了一条可行的路线。

▲ Abstract

Future quantum networks will enable the distribution of entanglement between distant locations and allow applications in quantum communication, quantum sensing and distributed quantum computation. At the core of this network lies the ability to generate and store entanglement at remote, interconnected quantum nodes. Although various remote physical systems have been successfully entangled, none of these realizations encompassed all of the requirements for network operation, such as compatibility with telecommunication (telecom) wavelengths and multimode operation. Here we report the demonstration of heralded entanglement between two spatially separated quantum nodes, where the entanglement is stored in multimode solid-state quantum memories. Entanglement between quantum memories placed in different laboratories is heralded by the detection of a telecom photon at a rate up to 1.4 kilohertz, and the entanglement is stored in the crystals for a pre-determined storage time up to 25 microseconds. We also show that the generated entanglement is robust against loss in the heralding path, and demonstrate temporally multiplexed operation, with 62 temporal modes. Our realization is extendable to entanglement over longer distances and provides a viable route towards field-deployed, multiplexed quantum repeaters based on solid-state resources.

▲ 摘要

由于通信信道中不可避免的损耗,在地面上纠缠分布的距离被限制在大约100公里。量子中继器可以通过使用量子存储器和纠缠交换来解决这个问题。作为量子中继器的基本链路,两个远程节点之间的两方纠缠的先兆分布只有通过内置型量子存储器才能实现。

作者提出了一个实验演示的预示纠缠之间的吸收量子存储器。他们建造了两个相隔3.5米的节点,每个节点包含一个偏振纠缠光子对源和一个带宽高达1千兆赫的固态量子存储器。

在中间站的联合钟态测量表明,两个量子存储器之间成功地分布了最大纠缠态,保真度为80.4±2.2%(±1标准差)。这里演示的量子节点和信道可以作为量子中继器的基本链路。

此外,节点中使用的宽带吸收量子存储器与确定性纠缠源兼容,同时支持多路复用,为实际的固态量子中继器和高速量子网络的构建铺平了道路。

▲ Abstract

Owing to the inevitable loss in communication channels, the distance of entanglement distribution is limited to approximately 100 kilometres on the ground. Quantum repeaters can circumvent this problem by using quantum memory and entanglement swapping. As the elementary link of a quantum repeater, the heralded distribution of two-party entanglement between two remote nodes has only been realized with built-in-type quantum memories. These schemes suffer from the trade-off between multiplexing capacity and deterministic properties and hence hinder the development of efficient quantum repeaters. Quantum repeaters based on absorptive quantum memories can overcome such limitations because they separate the quantum memories and the quantum light sources. Here we present an experimental demonstration of heralded entanglement between absorptive quantum memories. We build two nodes separated by 3.5 metres, each containing a polarization-entangled photon-pair source and a solid-state quantum memory with bandwidth up to 1 gigahertz. A joint Bell-state measurement in the middle station heralds the successful distribution of maximally entangled states between the two quantum memories with a fidelity of 80.4 ± 2.2 per cent (±1 standard deviation). The quantum nodes and channels demonstrated here can serve as an elementary link of a quantum repeater. Moreover, the wideband absorptive quantum memories used in the nodes are compatible with deterministic entanglement sources and can simultaneously support multiplexing, which paves the way for the construction of practical solid-state quantum repeaters and high-speed quantum networks.

▲ 摘要

由范德华材料形成的摩尔超晶格可以支持多种电子相,包括Mott绝缘体、超导体和广义Wigner晶体。当激子被摩尔超晶格限制时,一类新的激子出现了,这为实现人工激子晶体和量子光学效应带来了希望。

当这些摩尔激子与载流子耦合时,可能会产生相关态。然而,对于电荷耦合摩尔激子态,没有实验证据,也没有理论预测它们的性质。

本文报道了二硒化钨/二硒化钼异质薄膜中与摩尔势耦合的离子的光学特征。摩尔三离子态显示了多个尖锐的发射线与复杂的电荷密度依赖关系,这与传统三离子态的行为形成了鲜明的对比。

作者从辐射衰变中推断出对三离子态发射的不同贡献,其中剩余载流子驻留在不同的摩尔微型带中。

在不同的器件和样品区域观察到离子特征的变化,表明对样品的不均匀性和变异性有很高的灵敏度。这些离子特征的观察促进了对摩尔超晶格中高阶电子相关效应的进一步理论和实验研究。

▲ Abstract

Moiré superlattices formed by van der Waals materials can support a wide range of electronic phases, including Mott insulators, superconductors and generalized Wigner crystals. When excitons are confined by a moiré superlattice, a new class of exciton emerges, which holds promise for realizing artificial excitonic crystals and quantum optical effects. When such moiré excitons are coupled to charge carriers, correlated states may arise. However, no experimental evidence exists for charge-coupled moiré exciton states, nor have their properties been predicted by theory. Here we report the optical signatures of trions coupled to the moiré potential in tungsten diselenide/molybdenum diselenide heterobilayers. The moiré trions show multiple sharp emission lines with a complex charge-density dependence, in stark contrast to the behaviour of conventional trions. We infer distinct contributions to the trion emission from radiative decay in which the remaining carrier resides in different moiré minibands. Variation of the trion features is observed in different devices and sample areas, indicating high sensitivity to sample inhomogeneity and variability. The observation of these trion features motivates further theoretical and experimental studies of higher-order electron correlation effects in moiré superlattices.

▲ 摘要

人们对界面水的介电响应的理解依赖于线性响应近似:外电场诱导线性比例极化。这意味着对场的符号具有反对称性。然而,原子模拟表明,界面水的极化可能与线性响应有很大的偏差。

作者提出了一项针对这个问题的实验研究。他们测量了单层石墨烯电极附近重水(D2O)的振动和频率产生谱,以研究其在受控电化学条件下对外部电场的响应。OD拉伸的光谱显示了一个明显的不对称性对正负电极电荷。

当负电荷低于5 × 1012电子每平方厘米时,观察到非氢键OD基团指向石墨烯表面的峰值频率为每厘米2700次。在中性或正极电位下,这种“自由OD”峰突然消失,而光谱显示氢键OD物种的宽峰(在2300-2650每厘米)。

米勒定律将振动和频率产生响应与介电常数联系起来。观察到的与每米±3 × 108伏特电场线性响应的偏差使人们对将界面水作为简单介质处理的有效性提出了质疑。

▲ Abstract

Our understanding of the dielectric response of interfacial water, which underlies the solvation properties and reaction rates at aqueous interfaces, relies on the linear response approximation: an external electric field induces a linearly proportional polarization. This implies antisymmetry with respect to the sign of the field. Atomistic simulations have suggested, however, that the polarization of interfacial water may deviate considerably from the linear response. Here we present an experimental study addressing this issue. We measured vibrational sum-frequency generation spectra of heavy water (D2O) near a monolayer graphene electrode, to study its response to an external electric field under controlled electrochemical conditions. The spectra of the OD stretch show a pronounced asymmetry for positive versus negative electrode charge. At negative charge below 5 × 1012 electrons per square centimetre, a peak of the non-hydrogen-bonded OD groups pointing towards the graphene surface is observed at a frequency of 2,700 per centimetre. At neutral or positive electrode potentials, this ‘free-OD’ peak disappears abruptly, and the spectra display broad peaks of hydrogen-bonded OD species (at 2,300–2,650 per centimetre). Miller’s rule1 connects the vibrational sum-frequency generation response to the dielectric constant. The observed deviation from the linear response for electric fields of about ±3 × 108 volts per metre calls into question the validity of treating interfacial water as a simple dielectric medium.

▲ 摘要

在钙钛矿太阳能电池中,掺杂有机半导体常被用作位于光敏层和电极之间的电荷提取夹层。

作者报告了一种快速和可重复的掺杂方法,该方法涉及在紫外线下用CO2起泡旋涂液(piro-OMeTAD):LiTFSI溶液。CO2从光激发旋涂液中获得电子,迅速促进其p型掺杂并导致碳酸盐的沉淀。

经过CO2处理的中间层比原始薄膜的电导率高出约100倍,无需任何后处理即可实现稳定、高效的钙钛矿太阳能电池。该方法也可用于π共轭聚合物的增稠。

▲ Abstract

In perovskite solar cells, doped organic semiconductors are often used as charge-extraction interlayers situated between the photoactive layer and the electrodes. Here we report a fast and reproducible doping method that involves bubbling a spiro-OMeTAD:LiTFSI solution with CO2 under ultraviolet light. CO2 obtains electrons from photoexcited spiro-OMeTAD, rapidly promoting its p-type doping and resulting in the precipitation of carbonates. The CO2-treated interlayer exhibits approximately 100 times higher conductivity than a pristine film while realizing stable, high-efficiency perovskite solar cells without any post-treatments. We also show that this method can be used to dope π-conjugated polymers.

▲ 摘要

如果散装材料能够承受高负荷而没有任何不可逆转的损伤(如塑性变形),它通常是脆性的,并可能灾难性地失效。

这种强度和断裂韧性之间的权衡也延伸到二维材料空间中。六方氮化硼(h-BN)是一种介电二维材料,具有与石墨烯类似的高强度(约100吉帕)和弹性模量(约0.8兆帕)。

长期以来,人们一直认为它的断裂行为是类似的脆性,遵循Griffith定律。与预期相反,这里作者报道了单晶单层h-BN的高断裂韧性,其有效能量释放率比其格里菲斯能量释放率和石墨烯报告的能量释放率都高出一个数量级。观察了h-BN单分子层的稳定裂纹扩展,得到了相应的抗裂曲线。

由于裂纹尖端的非对称边缘弹性特性和裂纹扩展过程中的边缘交换,裂纹的挠度和分叉会反复发生,这从本质上增强了材料的韧性,使裂纹稳定扩展。作者的现场实验观察和理论分析表明,单层h-BN增加了实际效益和潜在的新技术机会,如为二维器件增加机械保护。

▲ Abstract

If a bulk material can withstand a high load without any irreversible damage (such as plastic deformation), it is usually brittle and can fail catastrophically. This trade-off between strength and fracture toughness also extends into two-dimensional materials space. Hexagonal boron nitride (h-BN) is a dielectric two-dimensional material with high strength (about 100 gigapascals) and elastic modulus (approximately 0.8 terapascals), which are similar to those of graphene. Its fracture behaviour has long been assumed to be similarly brittle, subject to Griffith’s law. Contrary to expectation, here we report high fracture toughness of single-crystal monolayer h-BN, with an effective energy release rate up to one order of magnitude higher than both its Griffith energy release rate and that reported for graphene. We observe stable crack propagation in monolayer h-BN, and obtain the corresponding crack resistance curve. Crack deflection and branching occur repeatedly owing to asymmetric edge elastic properties at the crack tip and edge swapping during crack propagation, which intrinsically toughens the material and enables stable crack propagation. Our in situ experimental observations, supported by theoretical analysis, suggest added practical benefits and potential new technological opportunities for monolayer h-BN, such as adding mechanical protection to two-dimensional devices.

Widespread deoxygenation of temperate lakes

温带湖泊普遍缺氧

▲ 摘要

温带湖泊含氧量出现了大范围、长期的下降。这一针对近400个湖泊在80年的时间里计算得出的趋势或许和气候变暖以及水体透明度下降有关。

该下降趋势可能会威胁到至关重要的的湖泊生态系统。水体系统的溶解氧浓度会影响养分平衡、生物多样性、饮用水质量和温室气体排放。虽然海洋的氧流失已经得到了证明,但人们对湖泊溶解氧浓度的变化一直不够了解,一定程度上是因为缺乏长期、大规模的研究。

为解决这一问题,作者编制了1941年至2017年间由政府、大学、非营利组织采集的393个温带湖泊(大部分位于欧美)的温度和溶解氧测量数据。这些淡水环境减少的溶解氧是海洋中观测到的2倍到9倍左右。

作者指出,水温上升与表层水氧浓度下降有关,而深层水氧含量下降则与更强的热分层(不同深度形成不同的温跃层)以及水体透明度降低有关。

作者还指出了这些趋势的一些例外,比如大量湖泊(87个)的水温和溶解氧浓度都出现了上升。

不过,这种反常现象或许是由水华导致的——水华可能会让表层的氧浓度升高,深层的氧溶解度降低。作者总结称,人类活动和气候变暖预计将继续导致湖泊溶解氧的进一步流失,必须采取持续、严格的湖泊系统管理措施以应对这些影响。

▲ Abstract

The concentration of dissolved oxygen in aquatic systems helps to regulate biodiversity, nutrient biogeochemistry, greenhouse gas emissions, and the quality of drinking water. The long-term declines in dissolved oxygen concentrations in coastal and ocean waters have been linked to climate warming and human activity, but little is known about the changes in dissolved oxygen concentrations in lakes. Although the solubility of dissolved oxygen decreases with increasing water temperatures, long-term lake trajectories are difficult to predict. Oxygen losses in warming lakes may be amplified by enhanced decomposition and stronger thermal stratification or oxygen may increase as a result of enhanced primary production. Here we analyse a combined total of 45,148 dissolved oxygen and temperature profiles and calculate trends for 393 temperate lakes that span 1941 to 2017. We find that a decline in dissolved oxygen is widespread in surface and deep-water habitats. The decline in surface waters is primarily associated with reduced solubility under warmer water temperatures, although dissolved oxygen in surface waters increased in a subset of highly productive warming lakes, probably owing to increasing production of phytoplankton. By contrast, the decline in deep waters is associated with stronger thermal stratification and loss of water clarity, but not with changes in gas solubility. Our results suggest that climate change and declining water clarity have altered the physical and chemical environment of lakes. Declines in dissolved oxygen in freshwater are 2.75 to 9.3 times greater than observed in the world’s oceans and could threaten essential lake ecosystem services.
