A new study published in Physical Review A suggests that, somewhat counterintuitively, quantum particles have a chance of moving backwards, even when pushed forwards. The rest of this article is ...

Landslides are one striking example of erosion. When the bonds that hold particles of dirt and rock together are overwhelmed by a force — often in the form of water — sufficient to pull the rock and ...

Researchers from the Cavendish Laboratory have modelled a quantum walk of identical particles that can change their fundamental character by simply hopping across a domain wall in a one-dimensional ...

Peer Fischer outlines the prospects for creating “nanoswimmers” that can be steered through the body to deliver drugs directly to their targets Moving right along: Nanopropellers can swim through ...

Weyl particles are not particles which can move on their own (like electrons or protons), they only exist as 'quasiparticles' within a solid material. Now, for the first time, such Weyl particles have ...

Researchers report that nonlocality is a universal property of the world, regardless of how and at what speed quantum particles move. The phenomenon of quantum nonlocality defies our everyday ...

Active matter: this microscope image shows part of a cluster of self-propelled particles, colour-coded according to their distance from the centre. (Courtesy: Jie Zhang, Ricard Alert, Jing Yan, Ned S ...
