High-temperature expansion for frustrated magnets: Application to the J1-J2 model on the BCC lattice
Johannes Richter, Patrick Müller, Andre Lohmann +1
We present the high-temperature expansion up to 11th order for the specific heat and the uniform susceptibility and up to 9th order for the structure factor o…

Hubbard models with nearly flat bands: Ground-state ferromagnetism driven by kinetic energy
Patrick Müller, Johannes Richter, Oleg Derzhko
We consider the standard repulsive Hubbard model with a flat lowest-energy band for two one-dimensional lattices (diamond chain and ladder) as well as for a two-dimensional lattice…
