Competing many-body instabilities and unconventional superconductivity in graphene
Maximilian Kiesel, Christian Platt, Werner Hanke +2
The band structure of graphene exhibits van Hove singularities (VHS) at doping x=+- 1/8 away from the Dirac point. Near the VHS, interactions effects, enhanced due to the large den…
Mechanism for a Pairing State with Time-Reversal Symmetry Breaking in Iron-Based Superconductors
Christian Platt, Ronny Thomale, Carsten Honerkamp +2
The multipocket Fermi surfaces of iron-based superconductors promote pairing states with both s_{+-}-wave and d_{x^2-y^2}-wave symmetry. We argue that the competition between these…
From density functional theory to the functional renormalization group: superconductivity in the iron pnictide LiFeAs
Christian Platt, Ronny Thomale, Werner Hanke
A combined density functional theory and functional renormalization group method is introduced which takes into account orbital-dependent interaction parameters to derive the effec…
Exotic d-wave superconductivity in strongly hole doped K(x)Ba(1-x)Fe2As2
Ronny Thomale, Christian Platt, Werner Hanke +2
We investigate the superconducting phase in the K(x)Ba(1-x)Fe2As2 122 compounds from moderate to strong hole-doping regimes. Using functional renormalization group, we show that wh…
