In this gapless superconducting state, zero-energy quasiparticles reside on a segment of the normal-state Fermi surface, whereas the remaining Fermi surface is still gapped. We use quasiparticle interference to image the field-controlled Fermi surface of bismuth telluride (Bi2Te3) thin films under proximity effect from the superconductor niobium diselenide (NbSe2). A small applied in-plane magnetic field induces a screening supercurrent, which leads to finite-momentum pairing on the topological surface states of Bi2Te3. We identify distinct interference patterns that indicate a gapless superconducting state with a segmented Fermi surface. Our results reveal the strong impact of finite Cooper pair momentum on the quasiparticle spectrum.Time-of-flight 3D imaging through multimode optical fibersduomoguangxianfeixingshijian3Dchengxiang▲ zuozhe：DAAN STELLINGA, DAVID B.

Depth is recovered by measuring the round-trip flight time of laser pulses, typically using collection optics of several centimeters in diameter. We demonstrate near–video-rate 3D imaging through multimode fibers with a total aperture of several hundred micrometers. We implement aberration correction using wavefront shaping synchronized with a pulsed source and scan the scene at ~23,000 points per second. We image moving objects several meters beyond the end of an ~40-centimeters-long fiber of 50-micrometer core diameter at frame rates of ~5 hertz. Our work grants far-field depth-resolving capabilities to ultrathin microendoscopes, which we expect to have applications to clinical and remote inspection scenarios.rengongzhinengArtificial IntelligencePushing the frontiers of density functionals by solving the fractional electron problemjiejuefenshudianziwenti，tuidongmidufanhanjinzhan▲ zuozhe：JAMES KIRKPATRICK, BRENDAN MCMORROW, DAVID H.

We overcame this fundamental limitation by training a neural network on molecular data and on fictitious systems with fractional charge and spin. The resulting functional, DM21 (DeepMind 21), correctly describes typical examples of artificial charge delocalization and strong correlation and performs better than traditional functionals on thorough benchmarks for main-group atoms and molecules. DM21 accurately models complex systems such as hydrogen chains, charged DNA base pairs, and diradical transition states. More crucially for the field, because our methodology relies on data and constraints, which are continually improving, it represents a viable pathway toward the exact universal functional.cailiaokexueMaterials ScienceElemental electrical switch enabling phase segregation–free operationdanyuansudianzikaiguanshixianwuxiangfenlicaozuo▲ zuozhe：JIABIN SHEN, SHUJING JIA, NANNAN SHI, QINGQIN GE, TAMIHIRO GOTOH, SHILONG LV, ET AL.▲ lianjie：https://www.science.org/doi/10.1126/science.abi6332▲ zhaiyaofeiyishixingxiangbiancunchuqiyichenggongshangyehua，danruoxiangjinyibujiangmidusuofangdao10namiyixia，zecunchudanyuanhexiangguanchuizhiduidiedeshuangduanjierukaiguanxuyaozaichengfenhejiegoushanggengjunzhidecailiao。xuanzekaiguandaduoweifeijingliuxishuangxiangzuozhikaiguan（OTS），zaifeijingtaixiayunxingdefeixianxingdianliuxiangyinggaoyuzuozhidianya。raner，tamenmuqianbeisuoshiyongdesijiahuogengduojialiushuhuahewuchengfensuoyinrudehuaxuefuzaxingsuoyingxiang。yanjiuzutichuliaoyizhongdanyuansuzuo（Te）yishixingkaiguan，juyoujiaodadequdongdianliumidu（≥11zhaoan/pingfanglimi）de，yue103kai/guandianliubi，kaiguansudukuaiyu20namiao。diguanduandianliuyuanyuTe-dianjijiemiancunzaidayue0.95dianzifuxiaotejishilei，erchunTedeshuntaidianyamaichongyoudaodejing-yerongrongzhuanbiandaozhigaokaiduandianliu。gaiyanjiufaxiandedanyuansudianzikaiguankenengyouzhuyushixiangengmijidecunchuxinpian。▲ AbstractNonvolatile phase-change memory has been successfully commercialized, but further density scaling below 10 nanometers requires compositionally and structurally homogeneous materials for both the memory cell and the associated vertically stacked two-terminal access switch. The selector switches are mostly amorphous-chalcogenide Ovonic threshold switches (OTSs), operating with a nonlinear current response above a threshold voltage in the amorphous state. However, they currently suffer from the chemical complexity introduced by the quaternary or even more diverse chalcogenide compositions used. We present a single-element tellurium (Te) volatile switch with a large (≥11 megaamperes per square centimeter) drive current density, ~103 ON/OFF current ratio, and faster than 20 nanosecond switching speed. The low OFF current arises from the existence of a ~0.95–electron volt Schottky barrier at the Te–electrode interface, whereas a transient, voltage pulse–induced crystal-liquid melting transition of the pure Te leads to a high ON current. Our discovery of a single-element electrical switch may help realize denser memory chips.Detection of graphene’s divergent orbital diamagnetism at the Dirac pointzaidilakediantanceshimoxideguidaokangcixing▲ zuozhe：J.

However, the singular orbital magnetism of undoped graphene, a fundamental signature of the characteristic Berry phase of graphene’s electronic wave functions, has been challenging to measure in a single flake. Using a highly sensitive giant magnetoresistance (GMR) sensor, we have measured the gate voltage–dependent magnetization of a single graphene monolayer encapsulated between boron nitride crystals. The signal exhibits a diamagnetic peak at the Dirac point whose magnetic field and temperature dependences agree with long-standing theoretical predictions. Our measurements offer a means to monitor Berry phase singularities and explore correlated states generated by the combined effects of Coulomb interactions, strain, or moiré potentials.diqiukexueEarth ScienceMultidimensional tropical forest recoveryduoweiredaisenlinhuifu▲ zuozhe：LOURENS POORTER, DYLAN CRAVEN, CATARINA C.

We analyze how 12 forest attributes recover during secondary succession and how their recovery is interrelated using 77 sites across the tropics. Tropical forests are highly resilient to low-intensity land use; after 20 years, forest attributes attain 78% (33 to 100%) of their old-growth values. Recovery to 90% of old-growth values is fastest for soil (<1 decade) and plant functioning (<2.5 decades), intermediate for structure and species diversity (2.5 to 6 decades), and slowest for biomass and species composition (>12 decades). Network analysis shows three independent clusters of attribute recovery, related to structure, species diversity, and species composition. Secondary forests should be embraced as a low-cost, natural solution for ecosystem restoration, climate change mitigation, and biodiversity conservation.zhongqingtonglianglongjinqizaoyuliansailianxulianglunbusheng，qiuduishangyilun1-1zhanpingguangxipingguohazuo，danbenlunque0-2shugeiyuanbenzaibaojiqudeqiuduiliaoningtieren。lianxudeliangchangbusheng，weizhongqingtonglianglongdechongchaozhilucaixialiaoyiji“shache”。
