Classical and Quantum-like approaches to Charged-Particle Fluids in a Quadrupole

S. De Nicola, R. Fedele, V. I. Man'ko

A classical description of the dynamics of a dissipative charged-particle fluid in a quadrupole-like device is developed. It is shown that the set of the classical fluid equations…

Tomographic map within the framework of star-product quantization

Olga V. Man'ko, Vladimir I. Man'ko, Giuseppe Marmo

Tomograms introduced for the description of quantum states in terms of probability distributions are shown to be related to a standard star-product quantization with appropriate ke…

Alternative commutation relations, star products and tomography

Olga V. Man'ko, V. I. Man'ko, G. Marmo

Invertible maps from operators of quantum obvservables onto functions of c-number arguments and their associative products are first assessed. Different types of maps like Weyl-Wig…

Quantum tomography as a tool for the characterization of optical devices

G. Mauro D'Ariano, Matteo G. A. Paris, Martina De Laurentis +2

We describe a novel tool for the quantum characterization of optical devices. The experimental setup involves a stable reference state that undergoes an unknown quantum transformat…

Gravitational effects on a rigid Casimir cavity

Enrico Calloni, Luciano Di Fiore, Giampiero Esposito +2

Vacuum fluctuations produce a force acting on a rigid Casimir cavity in a weak gravitational field. Such a force is here evaluated and is found to have opposite direction with resp…

Vacuum fluctuation force on a rigid Casimir cavity in a gravitational field

Enrico Calloni, Luciano Di Fiore, Giampiero Esposito +2

We discuss the possibility of verifying the equivalence principle for the zero-point energy of quantum electrodynamics, by evaluating the force, produced by vacuum fluctuations, ac…

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…
