UPS and electric maintenance is scheduled for Wednesday, November 27th, 2024, 08:30 - 12:00. A downtime of this service might occur for up to 30 minutes.
In this talk I will discuss the physics of heavy-fermion systems and my current research in this field, including topological systems and exotic effects in this category. Starting from simple concepts in condensed matter theory and quantum mechanics, I will briefly explain the origin of the Kondo effect and how heavy Kondo-bands can form in real-world alloys. In that context, dynamical mean-field theory (DMFT) and the non-crossing approximation (NCA) will be briefly discussed as methods to numerically solve such systems. Finally, I will present results of applying these methods to solve bulk topological Kondo-insulators like SmB6 and the quadrupolar two-channel Kondo effect in PrV2Al20.
