Duality symmetry for star products
V. I. Man'ko, G. Marmo, P. Vitale
A duality property for star products is exhibited. In view of it, known star-product schemes, like the Weyl-Wigner-Moyal formalism, the Husimi and the Glauber-Sudarshan maps are re…
Probability representation in quantum field theory
V. I. Man'ko, L. Rosa, P. Vitale
The recently proposed probability representation of quantum mechanics is generalized to quantum field theory. We introduce a probability distribution functional for field configura…
Variational Formulation of Linear Time-Dependent Invariants
O. Castaños, R. López-Peña, V. I. Man'ko
It is shown that linear time-dependent invariants for arbitrary multi\-dimensional quadratic systems can be obtained from the Lagrangian and Hamiltonian formulation procedures by c…
Squeezing in a 2-D generalized oscillator
O. Castaños, R. López-Peña, V. I. Man'ko
A two-dimensional generalized oscillator with time-dependent parameters is considered to study the two-mode squeezing phenomena. Specific choices of the parameters are used to dete…
