We study the Kondo effect in three-dimensional (3D) Dirac materials and Weyl semimetals.
We find the scaling of the Kondo temperature with respect to the doping n and the coupling J …

Motivated by the unconventional superconductivity observed in heavy-fermion metals, we
investigate pairing susceptibilities near a continuous quantum phase transition of the Kondo …

The Anderson impurity model with a density of states ρ (ɛ)∝| ɛ| r containing a power-law
pseudogap centered on the Fermi energy (ɛ= 0) features for 0< r< 1 a Kondo-destruction …

We study the thermal and nonthermal steady-state scaling functions and the steady-state
dynamics of a model of local quantum criticality. The model we consider, ie, the pseudogap …

We study the impurity entanglement entropy S e in quantum impurity models that feature a
Kondo-destruction quantum critical point (QCP) arising from a pseudogap in the conduction …

Quantum criticality in systems of local moments interacting with itinerant electrons has
become an important and diverse field of research. Here we review recent results which …

We investigate theoretically the quantum phase transition (QPT) between the one-channel
Kondo (1CK) and two-channel Kondo (2CK) fixed points in a quantum dot coupled to helical …

We investigate the influence of an additional bosonic bath onto the real-time dynamics of a
localized orbital coupled to conduction band with an energy-dependent coupling function …

In condensed matter physics we generally have to deal with a large number O (1023) of
interacting particles. Their interaction is described quantum-mechanically by a Hamiltonian …

The lecture notes in this Autumn School describe many quantum impurity problems of
current interest in connection with the physics of strongly correlated electrons, as well as …
