Schwinger Boson approach to the fully screened Kondo model
J. Rech, P. Coleman, G. Zarand +1
We apply the Schwinger boson scheme to the fully screened Kondo model and generalize the method to include antiferromagnetic interactions between ions. Our approach captures the Ko…
Theory of Manganese-Manganese interaction in GaMnAs
P. Redlinski, G. Zarand, B. Janko
We investigate the interaction of two Mn ions in the dilute magnetic semiconductor GaMnAs using the variational envelope wave function approach within the framework of six band mod…
Disorder, spin-orbit, and interaction effects in dilute
Gregory A. Fiete, Gergely Zarand, Kedar Damle +1
We derive an effective Hamiltonian for in the dilute limit, where can be described in terms of spin …
Frustration of Decoherence in Open Quantum Systems
E. Novais, A. H. Castro Neto, L. Borda +2
We study a model of frustration of decoherence in an open quantum system. Contrary to other dissipative ohmic impurity models, such as the Kondo model or the dissipative two-level…
