    Correlated order at the tip** point in the kagome metal CsV3Sb5

    Spontaneously broken symmetries are at the heart of many phenomena of quantum matter and physics more generally. However, determining the exact symmetries that are broken can be challenging due to imperfection...

    Distinct switching of chiral transport in the kagome metals KV3Sb5 and CsV3Sb5

    The kagome metals AV3Sb5 (A = K, Rb, Cs) present an ideal sandbox to study the interrelation between multiple coexisting correlated phases such as charge order and superconductivity. So far, no consensus on the m...

    Quasi-symmetry-protected topology in a semi-metal

    The crystal symmetry of a material dictates the type of topological band structure it may host, and therefore, symmetry is the guiding principle to find topological materials. Here we introduce an alternative ...

    Magnetic electron collimation in three-dimensional semi-metals

    While electrons moving perpendicular to a magnetic field are confined to cyclotron orbits, they can move freely parallel to the field. This simple fact leads to complex current flow in clean, low carrier densi...

    Engineering medium-range order and polyamorphism in a nanostructured amorphous alloy

    Like crystalline materials, the properties of amorphous materials can be tailored by tuning the local atomic-to-nanoscale structural configurations. Polyamorphism is evident by the coexistence of kinetically s...

    Anomalous quantum oscillations and evidence for a non-trivial Berry phase in SmSb

    Topologically non-trivial electronic structures can give rise to a range of unusual physical phenomena, and the interplay of band topology with other effects such as electronic correlations and magnetism requi...

    Possible Weyl fermions in the magnetic Kondo system CeSb

    Materials where the electronic bands have unusual topologies allow for the realisation of novel physics and have a wide range of potential applications. When two electronic bands with linear dispersions inters...

    Differential gene expression profile in ischemic myocardium of Wistar rats with acute myocardial infarction

    To determine the differential genes in ischemic myocardium of Wistar rats with acute myocardial infarction (AMI), we constructed two differential gene expression profiles. AMI model was generated by ligation o...
