Thermodynamics and screening in the Ising-Kondo model
K. Bauerbach, Z. M. M. Mahmoud, F. Gebhard
We introduce and study a simplification of the symmetric single-impurity Kondo model. In the Ising-Kondo model, host electrons scatter off a single magnetic impurity at the origin…
Gutzwiller variational approach to the two-impurity Anderson model at particle-hole symmetry
Thorben Linneweber, Jörg Bünemann, Zakaria M. M. Mahmoud +1
We study Gutzwiller-correlated wave functions as variational ground states for the two-impurity Anderson model (TIAM) at particle-hole symmetry as a function of the impurity separa…
Non-interacting two-impurity Anderson model on a lattice at particle-hole symmetry
Zakaria M. M. Mahmoud, Jörg Bünemann, Florian Gebhard
We study the non-interacting two-impurity Anderson model on a lattice using the Green function equation-of-motion method. A case of particular interest is the RKKY limit that is ch…
Non-interacting single-impurity Anderson model: solution without using the equation-of-motion method
Zakaria M. M. Mahmoud, Florian Gebhard
Ground-state properties of the non-interacting symmetric single-impurity Anderson model (SIAM) are derived from the corresponding eigenenergy equation. Explicit formulae are given…
