Bottom-up insight into crowd dynamics

Stampedes unfortunately occur on too regular a basis. Previously, physicists developed numerous models of crowd evacuation dynamics. Their analyses focused on disasters such as the yearly Muslim Hajj or of the Love Parade ...

Quasi-particle swap between graphene layers

Belgian scientists have used a particle physics theory to describe the behaviour of particle-like entities, referred to as excitons, in two layers of graphene, a one-carbon-atom-thick honeycomb crystal. In a paper published ...

Nano-pea pod model widens electronics applications

Periodic chain-like nanostructures are widely used in nanoelectronics. Typically, chain elements include the likes of quantum rings, quantum dots, or quantum graphs. Such a structure enables electrons to move along the chain, ...

When noise gets electrons moving

Studying the motion of electrons in a disordered environment is no simple task. Often, understanding such effects requires a quantum simulator designed to expose them in a different physical setup.

Atom-based analogues to electronic devices

Scientists have pushed back the boundaries of atom-based transport, creating a current by characterizing the many-body effects in the transport of the atoms along a periodic lattice. This work by Anton Ivanov and colleagues ...
