The realization of new classes of ground states in strongly correlated electron systems
continues to be a major issue in condensed matter physics. Heavy fermion materials, whose …

We analyze spin density waves (SDWs) in the Hubbard model on a square lattice within the
framework of inhomogeneous dynamical mean field theory (IDMFT). Do** the half-filled …

How many magnetic moments periodically arranged on a metallic surface are needed to
generate a coherent Kondo lattice behavior? We investigate this fundamental issue within …

The competition between antiferromagnetic (AF) order and singlet formation is a central
phenomenon of the Kondo and periodic Anderson Hamiltonians and of the heavy fermion …

We investigate the effect of disorder on the dynamical spectrum of layered f-electron
systems. With random dilution of f sites in a single Kondo insulating layer, we explore the …

The competition between the Ruderman-Kittel-Kasuya-Yosida effect and Kondo effect is a
central subject of the periodic Anderson model. By using the density matrix embedding …

We investigate magnetic and superconducting properties of layered f-electron superlattices
within the fluctuation exchange approximation (FLEX). We show that spin fluctuations, which …

Disorder is ubiquitous in real materials and influences the physical properties like the
conductivity to varying degrees. If electron-electron interactions are strong, theoretical and …
