Extended Cahill-Glauber formalism for finite dimensional spaces: I. Fundamentals
M. Ruzzi, M. A. Marchiolli, D. Galetti
The Cahill-Glauber approach for quantum mechanics on phase-space is extended to the finite dimensional case through the use of discrete coherent states. All properties and features…

Quantum spin tunneling in a soluble quasi-spin model: An angle-based potential description
D. Galetti, C. L. Lima, B. M. Pimentel
We propose an approach which allows to construct and use a potential function written in terms of an angle variable to describe interacting spin systems. We show how this can be im…
