We investigate an application of the variational principle of Balian and Venironi for density operators and observables. Our choice for the trial spaces incorporates correlations in the density operator. It allows one to calculate the expectation values of both one-body and twobody observables. We d
## The quanta1 time evolution of a one-dimensional Gaussian wave packet according to the time-dependent variational principle (TDVP) is shown to be formally equivalent to the classical motion of a particle in a two-dimensional potential. The formal and practical advantages of the TDVP approach are
The time-dependent coupled cluster method (TDCCM ) has been applied to the photodissociation dynamics of linear triatomits using the Beswick-Jortner model. The autocorrelation function and absorption spectra have been evaluated and the convergence of the method has been tested by evaluating the auto
