Abstract

We developed a technique for calculating two-time correlation functions based on a quantum trajectory approach. Our method requires the simulation of the evolution of a given set of density matrices only once. The evaluation can be carried out from the density matrix data obtained for any quantities, time arguments and initial conditions. The computational efficiency of the method is estimated and an example of application is presented.
