Manual for the Flexible DM-NRG code
O. Legeza, C. P. Moca, A. I. Toth +2
Quantum impurity models describe interactions between some local degrees of freedom and a continuum of non-interacting fermionic or bosonic states. The investigation of quantum imp…
Universal diffusive decay of correlations in gapped one-dimensional systems
Akos Rapp, Gergely Zarand
We apply a semiclassical approach to express finite temperature dynamical correlation functions of gapped spin models analytically. We show that the approach of [A. Rapp, G. Zarand…
Friedel oscillations induced surface magnetic anisotropy
A. Szilva, S. Gallego, M. C. Munoz +3
We present detailed numerical studies of the magnetic anisotropy energy of a magnetic impurity near the surface of metallic hosts (Au and Cu), that we describe in terms of a realis…
Spin-resolved spectra of Shiba multiplets from Mn impurities in MgB_2
Catalin Pascu Moca, Eugene Demler, Boldizsar Janko +1
We study the effect of magnetic Mn ions on the two-band superconductor MgB_2, and compute both the total and spin resolved scanning tunneling spectrum in the vicinity of the magnet…
Density matrix numerical renormalization group for non-Abelian symmetries
A. I. Toth, C. P. Moca, O. Legeza +1
We generalize the spectral sum rule preserving density matrix numerical renormalization group (DM-NRG) method in such a way that it can make use of an arbitrary number of not neces…
Dynamical correlations in the spin-half two-channel Kondo model
A. I. Toth, G. Zarand
Dynamical correlations of various local operators are studied in the spin-half two-channel Kondo (2CK) model in the presence of channel anisotropy or external magnetic field. A con…
