✍ Mohamed Benarous 📂 Article 📅 1998 🏛 Elsevier Science 🌐 English ⚖ 345 KB

The time-dependent variational principle proposed by Balian and Ve ne roni is used to provide an optimal value of the generating functional for the multi-time Green's functions of a set of bosonic observables Q + . By restricting the two trial quantities to gaussian operators, an explicit formula is
