Multi-disclinational description of pentagonal particles with subsurface layer free of twin boundaries We present the results on the modelling of structural changes in pentagonal small particles (PSPs) during their growth. We prove that after a certain critical size it becomes energetically favourab...

It’s a very interesting paper with my colleagues from St. Petersburg. Everyone knows about dislocations, which are translational defects in a solid body, but not everyone is familiar with disclinations, which are rotational defects.

My Quantum Cheshire Cat Sophie

Observation of a quantum Cheshire Cat in a matter-wave interferometer experiment Nature Communications - One of the paradoxical phenomena of quantum mechanics is the quantum Cheshire Cat, consisting of the apparent spatial separation of a particle and one of its properties....

On the ductile-brittle transition in polycrystalline metallic materials with dislocation defect dynamics The ductile-brittle transition in polycrystalline metallic materials with dislocation defect dynamics is interpreted using the fundamental Orowan relation. The main hypothesis of this paper is that...

Negative time observed in photon-atom interaction – Physics World Researchers find that a photon can spend a negative amount of time in an excited atomic state while passing through a cloud of atoms

Researchers determine that a photon can spend a negative amount of time in an excited atomic state while passing through a cloud of atoms - a finding with potential applications in studies of light-matter interactions and quantum sensing. 🧪⚛️ physicsworld.com/a/negative-t...
