Physikalisches Kolloquium

Antrittsvorlesung: Theory and simulation of strongly correlated plasmas and dense matter (Dr. Hanno Kählert, ITAP, CAU)

26.01.2021 von 16:15 bis 17:45


High density plasmas are fundamentally different from their low density counterparts in space or high temperature fusion reactors. Strong interactions give rise to novel phenomena such as liquid-like ordering and affect their thermodynamic and transport properties. The latter are important for the modeling of dense plasmas in inertial confinement fusion or warm dense matter in planetary interiors. Similar conditions occur at low temperatures or when highly charged ions are involved, which makes it possible to study strong coupling physics on a smaller scale with laser-cooled plasmas or charged dust particles. This talk gives an introduction to the physics of strongly correlated plasmas, their occurrence, and theoretical description. In particular, simulation methods have become indispensable tools to obtain reliable data for their properties in a regime where traditional plasma theory fails. As an example, I present results for the dynamic structure factor - a key quantity that is accessible experimentally and provides deep insight into the thermodynamic, transport, and dielectric properties of strongly correlated plasmas. Future challenges and possible directions for the field will be addressed.
