Magnetism in the Dilute Kondo Lattice Model

Gulacsi, Miklos; McCulloch, I P; Juozapavicius, A; Rosengren, A

Description

The one-dimensional dilute Kondo lattice model is investigated by means of bosonization for different dilution patterns of the array of impurity spins. The physical picture is very different if a commensurate or incommensurate doping of the impurity spins is considered. For the commensurate case, the obtained phase diagram is vertified using a non-Abelian density-matrix renormalization-group algorithm. The paramagnetic phase widens at the expense of the ferromagnetic phase as thef spins are...[Show more]
