Investigating the role of 'random walks' in particle diffusion

Several recent experiments identify unusual patterns in particle diffusion, hinting at some underlying complexity in the process which physicists have yet to discover. Through new analysis published in The European Physical ...

Quantum mechanics model unveils hidden patterns in stock markets

A new study published in Financial Innovation has developed a novel quantum model for stock market fluctuations that incorporates economic uncertainty and herding behavior. The study aims to provide a deeper understanding ...

Magnetic whirls pave the way for energy-efficient computing

Researchers of Johannes Gutenberg University Mainz and the University of Konstanz in Germany as well as of Tohoku University in Japan have been able to increase the diffusion of magnetic whirls, so called skyrmions, by a ...

Studying battery cycling on the beamline

During his Ph.D. with TUoS, ISIS facility development student Innes McClelland developed a cell for testing battery materials during their operation using muon spectroscopy and used it to study an increasingly vital cathode ...

Diffusion

Diffusion describes the spread of particles through random motion from regions of higher concentration to regions of lower concentration. The time dependence of the statistical distribution in space is given by the diffusion equation. The concept of diffusion is tied to that of mass transfer driven by a concentration gradient. Diffusion is invoked in the social sciences to describe the spread of ideas.
