معرفی
Peter Olsson is an Associate Professor in the Department of Physics at Umeå universitet, Sweden. His research focuses on the jamming transition in granular materials, employing computer simulations to study how these systems transition from fluid-like to solid-like states under shear. He investigates the dynamics of frictionless disks and ellipsoidal particles in two, three, and even four dimensions, emphasizing phenomena such as shear thickening, viscosity scaling, and orientational ordering.
Olsson's work delves into critical behavior at the jamming point, including relaxation times, rheological phase transitions, and finite-size effects. His studies often involve large-scale simulations (e.g., 65,536 particles) to analyze viscosity changes and particle dynamics under shear. Notable contributions include exploring dimensionality effects on viscosity exponents and the role of particle shape (e.g., ellipsoids) in rotational dynamics.
While no explicit scientific awards are listed, his extensive publication record in high-impact journals like Physical Review Letters and Physical Review E underscores his academic contributions. Collaborations with researchers such as Daniel Vågberg and Stephen Teitel highlight his collaborative approach to advancing understanding of jamming phenomena.
Olsson's research location is Fysikhuset, plan 1, Linneaus väg 20, Umeå, Sweden. His work bridges computational physics with soft matter and condensed matter systems, offering insights into fundamental questions about disorder and phase transitions in granular materials.
