Mean-field theory for superconductivity in twisted bilayer graphene
T. J. Peltonen, R. Ojajärvi, T. T. Heikkilä
Recent experiments show how a bilayer graphene twisted around a certain magic angle becomes superconducting as it is doped into a region with approximate flat bands. We investigate…

Two topologically distinct Dirac-line semimetal phases and topological phase transitions in rhombohedrally stacked honeycomb lattices
T. Hyart, R. Ojajärvi, T. T. Heikkilä
Three-dimensional topological semimetals can support band crossings along one-dimensional curves in the momentum space (nodal lines or Dirac lines) protected by structural symmetri…
