Introducing strong correlation effects into graphene by gadolinium intercalation
S. Link, S. Forti, A. Stöhr +11
Exotic ordered ground states driven by electronic correlations are expected to be induced in monolayer graphene when doped to the Van Hove singularity. Such doping levels are reach…
Multiband Dual Fermion Approach to Quantum Criticality in the Hubbard Honeycomb Lattice
Daniel Hirschmeier, Hartmut Hafermann, Alexander I. Lichtenstein
We study the Hubbard model on the honeycomb lattice in the vicinity of the quantum critical point by means of a multiband formulation of the Dual Fermion approach. Beyond the stron…
Mechanisms of finite temperature magnetism in the three-dimensional Hubbard model
Daniel Hirschmeier, Hartmut Hafermann, Emanuel Gull +2
We examine the nature of the transition to the antiferromagnetically ordered state in the half-filled three-dimensional Hubbard model using the dual-fermion multiscale approach. Co…
