Entanglement structure of adjoint representation of unitary group and tomography of quantum states
V. I. Man'ko, G. Marmo, E. C. G. Sudarshan +1
The density matrix of composite spin system is discussed in relation to the adjoint representation of unitary group U(n). The entanglement structure is introduced as an additional…

Trapped ions interacting with laser fields: a perturbative analysis without rotating wave approximation
P. Aniello, V. Man'ko, G. Marmo +3
The Hamiltonian describing a single ion placed in a potential trap in interaction with a laser beam is studied by means of a suitable perturbative approach. It is shown, in particu…

Purification of impure density operators and the recovery of entanglements
V. I. Man'ko, G. Marmo, E. C. G. Sudarshan +1
The need to retain the relative phases in quantum mechanics implies an addition law parametrized by a phase of two density operators required for the purification of a density matr…
