摘要：A key concept proposed by Landau to explain superfluid liquid helium is the elementary excitation of quantum particles called rotons1-8. The irregular arrangement of atoms in a liquid leads to the aperiodic dispersion of rotons, which played a pivotal role in understanding fractional quantum Hall liquids (magneto-rotons)9,10 and the supersolidity of Bose-Einstein condensates11-13. Even for a two-dimensional electron or dipole liquid, in the absence of a magnetic field, the repulsive interactio...

摘要：The interaction between planets and stellar winds can lead to atmospheric loss and is, thus, important for the evolution of planetary atmospheres1. The planets in our Solar System typically interact with the solar wind, whose velocity is at a large angle to the embedded stellar magnetic field. For planets without an intrinsic magnetic field, this interaction creates an induced magnetosphere and a bow shock in front of the planet2. However, when the angle between the solar wind velocity and the...

摘要：We can anticipate many false claims, including alleged mass voting by non-citizens or 'suspicious vans' outside polling booths. We should quickly counter them.
