The evolution of a quantum system characterized by a dynamical group G and subjected to
random interactions can be reduced, through the use of the generalized coherent states …

Using the Klauder approach the stable evolution of generalized coherent states (GCS) for
some groups (SU (2), SU (1, 1) and SU (N)) is considered and it is shown that one and the …

The exact and stable evolutions of generalized coherent states (GCS) for quantum systems
are considered by making use of the time-dependent integrals of motion method and of the …

Among the discrete evolution equations describing a quantum system ℋ S undergoing
repeated quantum interactions with a chain of exterior systems, we study and characterize …

We present a procedure for averaging one-parameter random unitary groups and random
self-adjoint groups. Central to this is a generalization of the notion of weak convergence of a …

The aim of this talk is to provide examples for the theory of (a class of) quantum stochastic
processes presented by JT Lewis in this issue [1]. It is not difficult to construct examples of …

The concept of generalized coherent states for an arbitrary Lie group is revisited. Their
analiticity properties are discussed showing that they lead naturally to a phase space …

A fairly general procedure is described for the construction of coherent states of the induced
representations of a general class of semi-direct product groups. The construction is much …

Given the C∗-algebra A of observables, the KMS condition is formulated in terms of the time
evolution α∗ t of a set S 0⊂ S (A) of “physical” states subject to certain natural conditions …
