We present a mapping of various correlated multi-impurity Anderson models to a cluster
model coupled to a number of effective conduction bands capturing its essential low-energy …

Tight-binding Hamiltonians with single and multiple orbitals exhibit an intriguing array of
magnetic phase transitions. In most cases the spin ordered phases are insulating, while the …

In this work, we derive a multi-fragment real-time extension of the projected density matrix
embedding theory (pDMET) designed to treat non-equilibrium electron dynamics in strongly …

We investigate the finite-temperature properties of an Anderson lattice with regularly
depleted impurities. The physics of this model is ruled by two different magnetic exchange …

The Kondo and periodic Anderson models describe many of the qualitative features of local
moments coupled to a conduction band, and thereby the physics of materials such as the …

We study the Kondo alloy model on a square lattice using dynamical mean-field theory for
Kondo substitution and disorder effects, together with static mean-field approximations. We …

We study the low energy states of the Kondo alloy model (KAM) as function of the magnetic
impurity concentration per site, x, and the conduction electron average site occupation, n c …

A site-selective extension of the dynamical mean-field approach is proposed and
implemented. The implementation supposes remaining single impurity problems to be …

Various novel effects in nanostructures of magnetic atoms exchange-coupled to a metallic
system of conduction electrons are reviewed. To this end we discuss analytical results and …
