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…

Symmetric single-impurity Kondo model on a tight-binding chain: a comparison of analytical and numerical ground-state approaches
Gergely Barcza, Kevin Bauerbach, Fabian Eickhoff +3
We analyze the ground-state energy, local spin correlation, impurity spin polarization, impurity-induced magnetization, and corresponding zero-field susceptibilities of the symmetr…
