Open Wilson chain numerical renormalization group approach to steady-state non-equilibrium quantum transport
Anand Manaparambil, Frithjof B. Anders
The numerical renormalization group (NRG) approach was developed to identify and quantify different equilibrium regimes of quantum impurity systems (QISs) with unprecedented accura…
Kondo breakdown in multi-orbital Anderson lattices induced by destructive hybridization interference
Fabian Eickhoff, Frithjof B. Anders
In this paper we consider a multi band extension to the periodic Anderson model. We use a single site DMFT(NRG) in order to study the impact of the conduction band mediated effecti…
Strong terahertz third-harmonic generation by kinetic heavy quasiparticles in CaRuO
C. Reinhoffer, Sven Esser, Sebastian Esser +6
We report on time-resolved nonlinear terahertz spectroscopy of a strongly correlated ruthenate, CaRuO, as a function of temperature, frequency and terahertz field strength. Thi…
Simplified approach to the magnetic blue shift of Mott gaps
Mohsen Hafez-Torbati, Frithjof B. Anders, Götz S. Uhrig
The antiferromagnetic ordering in Mott insulators upon lowering the temperature is accompanied by a transfer of the single-particle spectral weight to lower energies and a shift of…
Microscopic origin of the effective spin-spin interaction in a semiconductor quantum dot ensemble
Frederik Vonhoff, Andreas Fischer, Kira Deltenre +1
We present a microscopic model for a singly charged quantum dot (QD) ensemble to reveal the origin of the long-range effective interaction between the electron spins in the QDs. Wi…
Open Wilson chain numerical renormalization group approach to Green's functions
Jan Böker, Frithjof B. Anders
By combining Wilson's numerical renormalization group with a modified Bloch-Redfield approach we are able to eliminate the artificial broadening of the Lehmann representation of qu…
