A levitated nanoscale particle in vacuum represents an isolated system where researchers can study the transition between classical and quantum mechanics. It also offers a testbed for building new ...

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 ...

The answer to this question puts a spotlight on two revolutionary 19th-century scientists. In 1828, the Scottish botanist Robert Brown published his observation that tiny particles in suspension were ...

Observing light in motion is now possible thanks to an impressive breakthrough by researchers at the University of Toronto. They have developed a technology capable of capturing and simulating the ...

“I did not believe that it was possible to study the Brownian motion with such a precision.” From a letter from Albert Einstein to Jean Perrin (1909). On 30 April 1905, Einstein completed his doctoral ...

Numerical analysis of the effect of thermo- and diffusiophoretic forces on the motion of moderately large (0.01 ≲ Kn ≲ 0.3) combustion-generated (soot) particles and on the formation of soot-shell ...
