Integral representation of the density matrix of the XXZ chain at finite temperatures

Frank Göhmann, Andreas Klümper, Alexander Seel

We present an integral formula for the density matrix of a finite segment of the infinitely long spin-1/2 XXZ chain. This formula is valid for any temperature and any longitudinal…
