โœฆ Synopsis


Applying to boson systems the time-dependent variational principle of Balian and Ve ne roni, we derive approximate methods for calculating expectation values when both the measured observable and the density matrix are exponentials of quadratic forms of boson operators. In the zero-temperature limit, the variational equations provide a consistent way to evaluate transition probabilities.

We investigate the Dirac time-dependent variational method for a system of non-ideal Bosons interacting through an arbitrary two body potential. The method produces a set of non-linear time dependent equations for the variational parameters. In particular we have considered small oscillations about

We analyze the Poisson structure of the time-dependent meanfield equations for condensed bosons and construct the Lie Poisson bracket associated to these equations. The latter follow from the time-dependent variational principle of Balian and Ve ne roni when a Gaussian Ansatz is chosen for the densi

## Abstract In this paper, a new method to solve spaceโ€“timeโ€dependent nonโ€linear equations is proposed. After considering the variable coefficient of a nonโ€linear equation as a new dependent variable, some special types of spaceโ€“timeโ€dependent equations can be solved from corresponding spaceโ€“timeโ€i

The Gaussian time-dependent variational equations are used to explored the physics of (, 4 ) 3+1 field theory. We have investigated the static solutions and discussed the conditions of renormalization. Using these results and stability analysis we show that there are two viable non-trivial versions
