Rise and Fall of the Pseudogap in the Emery model: Insights for Cuprates
M. O. Malcolms, Henri Menke, Yi-Ting Tseng +4
The pseudogap in high-temperature superconducting cuprates is an exotic state of matter, displaying emerging Fermi arcs and a momentum-selective suppression of states upon cooling.…
Magnetic quantum criticality: The role of the Fermi surface geometry
D. R. Fus, S. Adler, M. O. Malcolms +5
We investigate magnetic quantum phase-transitions in bulk correlated metals. To this end, we focus on the Hubbard model on different cubic lattices as a function of temperature and…
Role of three-particle vertex within dual fermion calculations
T. Ribic, P. Gunacker, S. Iskakov +5
We investigate the influence of self-energy diagrams beyond the two-particle vertex level within dual fermion theory. Specifically, we calculate the local three-particle vertex and…
Diagrammatic routes to nonlocal correlations beyond dynamical mean field theory
G. Rohringer, H. Hafermann, A. Toschi +6
Strong electronic correlations pose one of the biggest challenges to solid state theory. We review recently developed methods that address this problem by starting with the local,…
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…
