Attosecond charge migration is a periodic evolution of the charge density at specific sites of a molecule on a time scale defined by the energy intervals between the electronic states involved. Here, we report the observation of charge migr...

Quantized vortices are a prototypical feature of superfluidity that have been observed in multiple quantum gas experiments. But the occurrence of vortices in dipolar quantum gases-a class of ultracold gases characterized by long-range aniso...
The optimal strategy balancing risk and speed predicts DNA damage checkpoint override times [0.03%]

Checkpoints arrest biological processes allowing time for error correction. The phenomenon of checkpoint override (also known as checkpoint adaptation, slippage, or leakage), during cellular self-replication is biologically critical but cur...
Ab initio predictions link the neutron skin of 208Pb to nuclear forces [0.03%]
从头算预言将208Pb的中子皮与核力联系起来

Heavy atomic nuclei have an excess of neutrons over protons, which leads to the formation of a neutron skin whose thickness is sensitive to details of the nuclear force. This links atomic nuclei to properties of neutron stars, thereby relat...
Josephson diode effect from Cooper pair momentum in a topological semimetal [0.03%]

Cooper pairs in non-centrosymmetric superconductors can acquire finite centre-of-mass momentum in the presence of an external magnetic field. Recent theory predicts that such finite-momentum pairing can lead to an asymmetric critical curren...
Transition from sub-Rayleigh anticrack to supershear crack propagation in snow avalanches [0.03%]
雪崩中雪层损伤演化及超切变雪灾滑坡应急救援研究进展

Bertil Trottet et al.
Snow slab avalanches, characterized by a distinct, broad fracture line, are released following anticrack propagation in highly porous weak snow layers buried below cohesive slabs. The anticrack mechanism is driven by the volumetric collapse...
Multi-scale spatial heterogeneity enhances particle clearance in airway ciliary arrays [0.03%]

Mucus clearance constitutes the primary defence of the respiratory system against viruses, bacteria and environmental insults [1]. This transport across the entire airway emerges from the integrated activity of thousands of multiciliated ce...

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

Maja D Bachmann et al.
In an idealized infinite crystal, the material properties are constrained by the symmetries of the unit cell. The point-group symmetry is broken by the sample shape of any finite crystal, but this is commonly unobservable in macroscopic met...
Surface-tension-induced budding drives alveologenesis in human mammary gland organoids [0.03%]

Organ development involves complex shape transformations driven by active mechanical stresses that sculpt the growing tissue 1,2. Epithelial gland morphogenesis is a prominent example where cylindrical branches transform into spherical alve...
