Advanced Seminar WS 2015/2016
"Exotic Quasiparticles in Condensed Matter"
Mo. 14:00-15:00 h at the Seminar Room 201 of the II. Physikalisches Institut, University of Cologne.
The aim of the Advanced Seminar in WS 2015/16 is to discuss exotic quasiparticles, which are in the focus of modern solid-state research. Examples are so-called Dirac fermions with linear dispersion relation representing relativistic quasi-particles or so-called Majorana fermions which represent their own anti-particles. Exotic many-body excitations in solids can also be viewed as composite quasiparticles, e.g. so-called electromagnons observed in multiferroic materials, or excitations in the so-called spin-ice systems that behave like magnetic monopoles.
The seminar talks shall focus on the presentation of the experimental signatures of such unusual quasiparticles or many-body excitations in different materials. In addition, the experimental techniques used for their observation and an overview about the underlying theoretical concepts should be given.
