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…
Realistic quantum critical point in one-dimensional two-impurity models
Benedikt Lechtenberg, Fabian Eickhoff, Frithjof B. Anders
We show that the two-impurity Anderson model exhibits an additional quantum critical point at infinitely many specific distances between both impurities for an inversion symmetric…
Spatial and temporal propagation of Kondo correlations
Benedikt Lechtenberg, Frithjof B. Anders
We address the fundamental question how the spatial Kondo correlations are building up in time assuming an initially decoupled impurity spin . We investigate the…
