This approach has inspired researchers to try their hand at twisting two-dimensional (2D) magnets, but such experiments have proven a difficult challenge. Song et al. made structures out of layers of the 2D magnet chromium triiodide with a small twist angle (see the Perspective by Lado). Using nitrogen vacancy centers in diamond as a magnetometer, the authors imaged the magnetic domains in both twisted monolayer and twisted trilayer structures. For twisted trilayers, a periodic pattern of ferromagnetic and antiferromagnetic domains was revealed.Floquet Hamiltonian engineering of an isolated many-body spin systemguliduotizixuanxitongdefuluokuitehamidungongcheng▲ zuozhe:SEBASTIAN GEIER, NITHIWADEE THAICHAROEN, CL?MENT HAINAUT, TITUS FRANZ, ANDRE SALZINGER, XANNIKA TEBBEN, DAVID GRIMSHANDL, GERHARD Z?RN, AND MATTHIAS WEIDEM?LLER▲ lianjie:https://www.science.org/doi/10.1126/science.abd9547▲ zhaiyaokongzhixianghuzuoyongshiduotixitongliangzigongchengdeguanjianyaosu。liyongshijianzhouqiqudong,yigefengbiliangzixitongdezirangeidingdeduotihamidunliangkeyizhuanhuaweiyigebiaoxianchujidabutongdonglixuetexingdeyouxiaomubiaohamidunliang。zuozhezaichaolengdeyuanziqitizhongyonglidebaotaidaibiaodezixuanxitonglaiyanshifuluokuitegongcheng。tongguoyingyongyixiliezixuancaozuo,tamengaibianliaoyouxiaohaisenbaoXYZhamidunliangdeduichengxing。yinci,zongzixuandesongchixingweibeijidadigaibianliao。guancedaodedonglixuekeyiyongbanjingdianmonilaidingxingdibozhuo。shejiguangfandehamidunliangweizaidanyideshiyanshezhizhongshixianfeipinghengdonglixuedeliangzimonitigongliaojudadejihui。▲ AbstractControlling interactions is the key element for the quantum engineering of many-body systems. Using time-periodic driving, a naturally given many-body Hamiltonian of a closed quantum system can be transformed into an effective target Hamiltonian that exhibits vastly different dynamics. We demonstrate such Floquet engineering with a system of spins represented by Rydberg states in an ultracold atomic gas. By applying a sequence of spin manipulations, we change the symmetry properties of the effective Heisenberg XYZ Hamiltonian. As a consequence, the relaxation behavior of the total spin is drastically modified. The observed dynamics can be qualitatively captured by a semiclassical simulation. Engineering a wide range of Hamiltonians opens vast opportunities for implementing quantum simulation of nonequilibrium dynamics in a single experimental setting.huaxueChemistryAccelerated dinuclear palladium catalyst identification through unsupervised machine learningtongguowujiandujiqixuexijiasushuanghezuocuihuajishibie▲ zuozhe:JULIAN A.

Here, we report an unsupervised machine learning workflow that uses only five experimental data points. It makes use of generalized parameter databases that are complemented with problem-specific in silico data acquisition and clustering. We showcase the power of this strategy for the challenging problem of speciation of palladium (Pd) catalysts, for which a mechanistic rationale is currently lacking. From a total space of 348 ligands, the algorithm predicted, and we experimentally verified, a number of phosphine ligands (including previously never synthesized ones) that give dinuclear Pd(I) complexes over the more common Pd(0) and Pd(II) species.Orbiting resonances in formaldehyde reveal coupling of roaming, radical, and molecular channelsjiaquanguidaogongzhenjieshimanyou、ziyoujihefenzitongdaodezuohe▲ zuozhe:CASEY D.

Surprisingly, no clear quantum signatures of roaming have been observed to date, despite the quantum nature of the roaming event. We found evidence of quantum dynamics in the photodissociation of formaldehyde near the roaming threshold. This is ascribed to resonances associated to H+HCO(Ka = 1) that have a profound impact on the CO rotational and translational energy distributions and cause the roaming fraction to vary by a factor of 2 over an energy range of 10 cm–1. The roaming pathway serves both to modulate and report on the complex vibrational dynamics and coupling among the three dissociation pathways in the excited molecule as it decays to products.dizhiheshengwuGeology & biologyGlobal response of fire activity to late Quaternary grazer extinctionsyehuoduiwandisijishicaodongwumiejuedequanqiuxiangying▲ zuozhe:ALLISON T.

Karp et al. present evidence that that herbivore-fire interactions affected fire on a global scale in the past. They compared the severity of late Quaternary continent-level megaherbivore extinctions with changes in paleofire activity calculated from sedimentary charcoal data from grassy biomes. The extent of extinctions varied between continents, and this pattern was reflected in the changes in fire activity. Fire frequency increased most where the megaherbivore extinctions were greatest (South America) and least where few extinctions occurred (Africa). This loss of large-bodied grazers in the Quaternary drastically altered global fire regimes.Adaptive evolution of flight in Morpho butterfliesdashandiefeixingdeshiyingxingjinhua▲ zuozhe:CAMILLE LE ROY, DARIO AMADORISAMUEL CHARBERETJAAP WINDTFLORIAN T.

Le Roy et al. looked at the Amazonian Morpho butterfly group and found differences in both morphological and behavioral perspectives across species that occupy the canopy relative the understory. Species that evolved to occupy the canopy have improved gliding abilities because of a combination of wing shape and flight behavior. The combination of these traits varied across species even within this single genus, which suggests that there was not one route that led to colonization of this part of the forest.jiejinghou,minjinglijikaizhandiaochachenggongsuodingyige4rendaoqietuanhuo,gaituanhuofengongmingque,yourenzaiwaifangfeng、jieying,qiyurenyuanzesuijixuanzemendian,caiqubaolipohuaimenchuangrushidengxingshishishidaoqie。
