Abstract
A method, using the Lanczos diagonalization technique and random sampl
ing, is introduced to evaluate finite-temperature static and dynamical
quantities in small many-body quantum systems. As an example the meth
od is applied to the calculation of the optical conductivity of a sing
le charge-carrier hole in the system of strongly correlated electrons,
as decribed by the t-J model.
