Interplay between charge, magnetic and superconducting order in a Kondo lattice with an attractive Hubbard interaction
Benedikt Lechtenberg, Robert Peters, Norio Kawakami
We investigate the competition between superconductivity, charge-ordering, magnetic-ordering, and the Kondo effect in a heavy fermion -wave superconductor described by a Kondo l…

Effective low-energy description of the two impurity Anderson model: RKKY interaction and quantum criticality
Fabian Eickhoff, Benedikt Lechtenberg, Frithjof B. Anders
We show that the RKKY interaction in the two-impurity Anderson model comprise two contributions: a ferromagnetic part stemming from the symmetrized hybridization functions and an a…

Equilibrium and real-time properties of the spin correlation function in the two-impurity Kondo model
Benedikt Lechtenberg, Frithjof B. Anders
We investigate the equilibrium and real-time properties of the spin correlation function in the two-impurity Kondo model for different distance…
