Nicolas Laflorencie- An introduction to many-body localization in condensed matter physics
Please note that photographs and videos may be taken during the event for news and publicity purposes.
Nicolas Laflorencie is Directeur de Recherche at CNRS and works at the Laboratoire de Physique Théorique in Toulouse, France. His research covers several subfields of condensed matter theory, such as quantum magnetism, entanglement properties in condensed matter physics, quantum disordered systems. Recently, he has been heavily involved in the very intense international activity related to Many-Body Localization physics.
An introduction to many-body localization in condensed matter physics
The first aim of this seminar is to give a general and pedagogical introduction to the so-called Many-Body Localization (MBL) phenomenon which occurs in a large class of disordered and interacting quantum systems. In a second part, I will focus on recent results obtained for the random-field Heisenberg chain: multifractal properties across the MBL transition , and a newly discovered chain breaking mechanism  which characterises the MBL regime.
