Phase-space descriptions of operators and the Wigner distribution in quantum mechanics II. The finite dimensional case
S. Chaturvedi, E. Ercolessi, G. Marmo +3
A complete solution to the problem of setting up Wigner distribution for N-level quantum systems is presented. The scheme makes use of some of the ideas introduced by Dirac in the…

Phase-space descriptions of operators and the Wigner distribution in quantum mechanics I. A Dirac inspired view
S. Chaturvedi, E. Ercolessi, G. Marmo +3
Drawing inspiration from Dirac's work on functions of non commuting observables, we develop a fresh approach to phase space descriptions of operators and the Wigner distribution in…

Low-Dimensional Spin Systems: Hidden Symmetries, Conformal Field Theories and Numerical Checks
C. Degli Esposti Boschi, E. Ercolessi, G. Morandi
We review here some general properties of antiferromagnetic Heisenberg spin chains, emphasizing and discussing the role of hidden symmetries in the classification of the various ph…
