Quantum criticality with a twist - interplay of correlations and Kohn anomalies in three dimensions
T. Schäfer, A. A. Katanin, K. Held +1
A general understanding of quantum phase transitions in strongly correlated materials is still lacking. By exploiting a cutting-edge quantum many-body approach, the dynamical verte…

Ultrafast and gigantic spin injection in semiconductors
M. Battiato, K. Held
The injection of spin currents in semiconductors is one of the big challenges of spintronics. Motivated by the ultrafast demagnetisation and spin injection into metals, we propose…

Nonlocal correlations and spectral properties of the Falicov-Kimball model
T. Ribic, G. Rohringer, K. Held
We derive an analytical expression for the local two-particle vertex of the Falicov-Kimball model, including its dependence on all three frequencies, the full vertex and all reduci…
