Alternative Hamiltonian Desciptions and Statistical Mechanics
E. Ercolessi, G. Marmo, G. Morandi
We argue here that, as it happens in Classical and Quantum Mechanics, where it has been proven that alternative Hamiltonian descriptions can be compatible with a given set of equat…

Geometry of mixed states and degeneracy structure of geometric phases for multi-level quantum systems. A unitary group approach
E. Ercolessi, G. Marmo, G. Morandi +1
We analyze the geometric aspects of unitary evolution of general states for a multilevel quantum system by exploiting the structure of coadjoint orbits in the unitary group Lie alg…
