title = "A fast fourier transform method for calculating the equilibrium density matrix",
abstract = "We calculate the low-temperature quantum density matrix by integrating numerically the Bloch equation. The initial condition is the classical high-temperature value of the density matrix. The integration method uses short {"}time{"} propagators computed by a fast Fourier transform method.",
