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 $C$ and the uniform susceptibility ${\chi }_0$ and up to 9th order for the structure factor $S_{\mathbf{Q}}$ o…
