Séminaire Magnétisme non conventionnel

Jeudi 20 juin à 14h00,
Salle Remy Lemaire, K223

Orateur : Nicolas Laflorencie (LPT, Toulouse)
"Disorder and impurities in quantum spin systems : old problems and new physical perspectives"

Abstract

The intrinsic or controlled presence of impurities and disorder in condensed matter systems and quantum magnets can have dramatic consequences, in particular when it competes with quantum fluctuations. In this talk, I will discuss some fundamental issues raised by the effect of disorder in interacting quantum spins, relevant for a number of experiments, but also for more theoretical aspects.
