Destruction of Kondo effect in cubic heavy fermion compound Ce3Pd20Si6
J. Custers, K. -A. Lorenzer, M. Müller +9
How ground states of quantum matter transform between one another reveals deep insights into the mechanisms stabilizing them. Correspondingly, quantum phase transitions are explore…
Magnetic phase diagram of CePt3B1-xSix
Daniela Rauch, Stefan Süllow, Matthias Bleckmann +5
We present a study of the main bulk properties (susceptibility, magnetization, resistivity and specific heat) of CePt_3B_(1-x)Si-x, an alloying system that crystallizes in a noncen…
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.…
