Anisotropic chiral d+id superconductivity in NaxCoO2 yH2O
Maximilian Kiesel, Christian Platt, Werner Hanke +1
Since its discovery, the superconducting phase in water-intercalated sodium cobaltates NaxCoO2 yH2O (x~0.3, y~1.3) has posed fundamental challenges in terms of experimental investi…
Unconventional Fermi surface instabilities in the Kagome Hubbard Model
Maximilian L. Kiesel, Christian Platt, Ronny Thomale
We investigate the competing Fermi surface instabilities in the Kagome tight-binding model. Specifically, we consider onsite and short-range Hubbard interactions in the vicinity of…
Sublattice Interference in the Kagome Hubbard Model
Maximilian Kiesel, Ronny Thomale
We study the electronic phases of the kagome Hubbard model (KHM) in the weak coupling limit around van Hove filling. Through an analytic renormalization group analysis, we find tha…
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…
The 3-Band Hubbard-Model versus the 1-Band Model for the high-Tc Cuprates: Pairing Dynamics, Superconductivity and the Ground-State Phase Diagram
W. Hanke, M. L. Kiesel, M. Aichhorn +2
One central challenge in high- superconductivity (SC) is to derive a detailed understanding for the specific role of the - and - orbital degrees o…
