First-principles simulations of heavy fermion cerium compounds based on the Kondo lattice.
We propose a new framework for first-principles calculations of heavy-fermion materials. These are described in terms of the Kondo lattice Hamiltonian with the parameters extracted from a realistic density functional based calculation which is then solved using continuous-time quantum Monte Carlo method and dynamical mean field theory. As an example, we show our results for the Néel temperature...
متن کاملHeavy fermion properties of the Kondo Lattice model
We study the S = 1/2 Kondo lattice model which is widely used to describe heavy fermion behavior. In conventional treatments of the model the Kondo interaction is decoupled in favour of a hybridization of conduction and localized f electrons. However, such an approximation breaks the local gauge symmetry and implicates that the local f-occupation is no longer conserved. To avoid these problems,...
متن کاملWeyl–Kondo semimetal in heavy-fermion systems
Insulating states can be topologically nontrivial, a well-established notion that is exemplified by the quantum Hall effect and topological insulators. By contrast, topological metals have not been experimentally evidenced until recently. In systems with strong correlations, they have yet to be identified. Heavy-fermion semimetals are a prototype of strongly correlated systems and, given their ...
متن کاملSuperconductivity in Heavy Fermion Compounds
The heavy electron state in intermetallic lanthanide and actinide compounds has its origin in the interplay of strong Coulomb repulsion in the 4fand 5fshells and their hybridisation with conduction band states. Heavy quasiparticles have mostly been observed in Ceand U-based intermetallics which are therefore at the focus of this review. Ideally the ground state in these strongly correlated elec...
متن کاملPhotoelectron Spectra and Bonding in Phosphorus Compounds'
The results of (low energy) photoelectron spectroscopy render possible a better appreciation of bonding in molecules. The application of the new experimental method is demonstrated utilizing representative phosphorus compounds, and the close symbiosis delineated with molecular orbital models. Among the topics discussed are: the element P4, phosphine PH3 and derivatives, phosphorus substituent e...
