Interplay of Correlations and Kohn Anomalies in Three Dimensions: Quantum Criticality with a Twist

Interplay of Correlations and Kohn Anomalies in Three Dimensions: Quantum Criticality with a Twist 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 vertex approximation, we make important progress, determining the quantum critical properties of the antiferromagnetic transition in the fundamental model for correlated electrons, the Hubbard model in three dimensions.
