Double Exchange model for nanoscopic clusters
D. Rotter, A. Valli, G. Sangiovanni +1
We solve the double exchange model on nanoscopic clusters exactly, and specifically consider a six-site benzene-like nanocluster. This simple model is an ideal testbed for studying…
Comparing +DMFT and LDA+DMFT for the testbed material SrVO
Ciro Taranto, Merzuk Kaltak, Nicolaus Parragh +4
We have implemented the +dynamical mean field theory (DMFT) approach in the Vienna ab initio simulation package. Employing the interaction values obtained from the locally unsc…
Anisotropic optical conductivity of the putative Kondo insulator CeRuSn
V. Guritanu, P. Wissgott, T. Weig +11
Kondo insulators and in particular their non-cubic representatives have remained poorly understood. Here we report on the development of an anisotropic energy pseudogap in the tetr…
Conserved quantities of SU(2)-invariant interactions for correlated fermions and the advantages for quantum Monte Carlo simulations
Nicolaus Parragh, Alessandro Toschi, Karsten Held +1
In the context of realistic calculations for strongly-correlated materials with - or -electrons the efficient computation of multi-orbital models is of paramount importance.…
Kinks in the periodic Anderson model
A. Kainz, A. Toschi, R. Peters +1
Recently, dynamical mean field theory calculations have shown that kinks emerge in the real part of the self energy of strongly correlated metals close to the Fermi level. This giv…
Exploring the Dark Side of Cuprate Superconductors: s-wave Symmetry of the Pseudogap
S. Sakai, S. Blanc, M. Civelli +12
We reveal the full energy-momentum structure of the pseudogap of underdoped high-Tc cuprate superconductors. Our combined theoretical and experimental analysis explains the spectra…
