Exact thermal properties of free-fermionic spin chains

Michal Bialonczyk et al.

Summary: An elementary algebraic approach is used to provide an exact description of integrable spin chains at finite temperature in the complete Hilbert space of the system. The focus is on spin chain models described in terms of free fermions, with comparisons to common approximations. Errors from these approximations near the critical point at low temperatures are identified. Additionally, the thermal distribution of observables in the transverse-field quantum Ising chain is characterized.
