Here, we report a realization of spin ice in a lattice of superconducting qubits. Unlike conventional artificial spin ice, our system is disordered by both quantum and thermal fluctuations. The ground state is classically described by the ice rule, and we achieved control over a fragile degeneracy point, leading to a Coulomb phase. The ability to pin individual spins allows us to demonstrate Gauss’s law for emergent effective monopoles in two dimensions. The demonstrated qubit control lays the groundwork for potential future study of topologically protected artificial quantum spin liquids.shengmingkexueLife ScienceHorizontally transmitted parasitoid killing factor shapes insect defense to parasitoidsshuipingchuanbodejishengfengzhisiyinzicuchengkunchongduijishengfengdefangyu▲ zuozhe：Laila Gasmi, Edyta Sieminska, Shohei Okuno, Rie Ohta, Cathy Coutu et al.▲ lianjie：https://science.sciencemag.org/content/373/6554/535▲ zhaiyaomochimujishengfenghekunchongbingdugongxiangtongyikunchongsuzhuzhijiancunzaijiejianjingzheng。ciqian，youyanjiujiadingjishengxingyouchongsuishouganrandejizhusiwanghuoyinzhengduojizhuziyuanersiwang。zaici，womenmiaoshuliaoyigejiyinjiazu——nijishengwushasiyinzi（pkf）——tabianmadedanbaizhiduixiaofujianfengyakedenijishengwuyoudu，bingjuedingliaojishengshifouchenggong。PkfszaijigekunchongzhibingDNAbingdukeheyixielinchimujiyinzuzhongbeifaxian。womentigongdezhengjubiaoming，zaikunchongdoubingdu、nangpaobingdu、ganzhuangbingduhelinchimukunchongzhongfaxiandePKFstongguoyoudaoyiganjishengfengxibaodiaowangdejizhi，duineijishengchongjuyoudengxiaoheteyideduxing。zhetuchuliaojishengfeng、bingduhetamendekunchongsuzhuzhijiandejinhuajunbeijingsai。▲ AbstractInterkingdom competition occurs between hymenopteran parasitoids and insect viruses sharing the same insect hosts. It has been assumed that parasitoid larvae die with the death of the infected host or as result of competition for host resources. Here we describe a gene family, parasitoid killing factor (pkf), that encodes proteins toxic to parasitoids of the Microgastrinae group and determines parasitism success. Pkfs are found in several entomopathogenic DNA virus families and in some lepidopteran genomes. We provide evidence of equivalent and specific toxicity against endoparasites for PKFs found in entomopoxvirus, ascovirus, baculovirus, and Lepidoptera through a mechanism that elicits apoptosis in the cells of susceptible parasitoids. This highlights the evolutionary arms race between parasitoids, viruses, and their insect hosts.cailiaokexueMaterials ScienceLiquid medium annealing for fabricating durable perovskite solar cells with improved reproducibilityyetijiezhituihuozhibeinaiyongdegaizuokuangtaiyangnengdianchi▲ zuozhe：Nengxu Li, Xiuxiu Niu, Liang Li, Hao Wang, et al.▲ lianjie：https://science.sciencemag.org/content/373/6554/561▲ zhaiyaozaici，womenbaogaoyizhongyetijiezhituihuo（LMA）jishu，takeyichuangzaoyigeqiangdadehuaxuehuanjinghehengdingdejiarechanglaidiaojiezhenggebaomoshangdejingtishengchang。yiwomendefangfakeyishengchanbaomojiejingdugao、quexianshao，suoxuhuaxuejiliangxuehezhengtibaomojunyunxingdebaomo。youcizhibeidegaizuokuangtaiyangnengdianchi（PSCs）chanshengwendinggonglvshuchuwei24.04%（renzhengwei23.7%，0.08 cm2），bingzai2000xiaoshideyunxinghourengbaochi95%dechushigonglvzhuanhuanxiaolv（PCE）。ciwai，1 cm2dePSCsxianshichu23.15%dewendinggonglvshuchu（renzhengPCEwei22.3%），bingzai1120xiaoshideyunxinghoubaochichushiPCEde90%，zheshuomingliaoguimohuazhizaodekexingxing。LMAduiqihoudeyilaixingjiaoxiao，quannianshengchanshebeidexingnengchayikeyihuluebuji。gaifangfaweiyikeguimohuahekezhongxiandefangshitigaogaizuokuangbaomoheguangfuqijiandezhiliangkaibiliaoyitiaoxindeyouxiaotujing。▲ AbstractHere, we report a liquid medium annealing (LMA) technology that creates a robust chemical environment and constant heating field to modulate crystal growth over the entire film. Our method produces films with high crystallinity, fewer defects, desired stoichiometry, and overall film homogeneity. The resulting perovskite solar cells (PSCs) yield a stabilized power output of 24.04% (certified 23.7%, 0.08 cm2) and maintain 95% of their initial power conversion efficiency (PCE) after 2000 hours of operation. In addition, the 1-cm2 PSCs exhibit a stabilized power output of 23.15% (certified PCE 22.3%) and keep 90% of their initial PCE after 1120 hours of operation, which illustrates their feasibility for scalable fabrication. LMA is less climate dependent and produces devices in-house with negligible performance variance year round. This method thus opens a new and effective avenue to improving the quality of perovskite films and photovoltaic devices in a scalable and reproducible manner.Half-integer quantized anomalous thermal Hall effect in the Kitaev material candidate α-RuCl3α-RuCl3zhongdebanzhengshuliangzihuafanchangrehuoerxiaoying▲ zuozhe：T.

We found that the half-integer thermal Hall plateau appears even for a magnetic field with no out-of-plane components. The measured field-angular variation of the quantized thermal Hall conductance has the same sign structure as the topological Chern number of the pure Kitaev spin liquid. This observation suggests that the non-Abelian topological order associated with fractionalization of the local magnetic moments persists even in the presence of non-Kitaev interactions in α-RuCl3.Linked Weyl surfaces and Weyl arcs in photonic metamaterialsguangzichaocailiaozhonglianjiewaierbiaomianhewaierhu▲ zuozhe：Shaojie Ma, Yangang Bi, Qinghua Guo, Biao Yang et al.▲ lianjie：https://science.sciencemag.org/content/373/6554/572▲ zhaiyaowomenyijuyougongchengdiancitexingdechaocailiaoweijichu，goujianliaoyigejuyouyang-danjizihewaierbiaomiandexitong，tongguoxuandingdesanweizikongjian，womenguanchadaoliaoyixieyouqudetihebiaomianxianxiang，ruwaierbiaomianhebiaomianwaierhudelianjie。womensuozhanshideguangziwaierbiaomianhewaierhuliyonggaoweituopudegainianlaikongzhidiancibozairengonggongchengguangzijiezhizhongdechuanbo。▲ AbstractWe constructed a system possessing Yang monopoles and Weyl surfaces based on metamaterials with engineered electromagnetic properties, leading to the observation of several intriguing bulk and surface phenomena, such as linking of Weyl surfaces and surface Weyl arcs, via selected three-dimensional subspaces.

Many of these materials have narrow bandgaps, especially for cooling applications. We developed SnSe crystals with a wide bandgap (Eg≈33 kBT) with attractive thermoelectric properties through Pb alloying. The momentum and energy multiband alignments promoted by Pb alloying resulted in an ultrahigh power factor of ~75 μW cm-1 K - 2 at 300 K, and an average figure of merit ZT of ~1.90. We found that a 31-pair thermoelectric device can produce a power generation efficiency of ~4.4% and a cooling ΔTmax of ~45.7 K. These results demonstrate that wide-bandgap compounds can be used for thermoelectric cooling applications.
