Examples of fractionalisation in one-dimensional synthetic matter

Dr. Przemyslaw Grzybowski
ICFO, The Institute of Photonic Science, Barcelona, Spain

Fractionalisation is a term used with respect to many-body phenomena in which quasiparticles do not share the same quantum numbers (statistics) as the system constituents. In this seminar, I will first recall several examples of fractionalisation in one-dimensional systems: spin-charge separation, quasiparticle deconfinement and Fractional Exclusion Statistics (FES). Then I will discuss how such phenomena appear in systems of correlated fermions and bosons we study in the context of quantum simulators.
