Graphical analysis of angular momentum for collision products

Autor: Michael Danos, Ugo Fano

Publikováno v: Physics Reports. 304:155-227

The complexity of atomic and nuclear structures and their collision processes involves conservation laws, bearing mainly on angular momenta; indeed angular momentum treatments prove most laborious. The analytic treatments, preferably carried out in R

Fragmentation of atomic systems

Autor: John L. Bohn, Ugo Fano

Publikováno v: Physical Review A. 53:4014-4020

We report recent progress toward a nonperturbative formulation of many-body quantum dynamics that treats all constituent particles on an equal footing. This formulation is capable of detailing the evolution of a system toward the diverse fragments in

Density matrices as polarization vectors

Autor: Ugo Fano

Publikováno v: Rendiconti Lincei. 6:123-130

Il concetto di matrice di densita ebbe origine attorno al 1930 nel corso di adattare alla meccanica quantistica la descrizione statistica di fenomeni classici, ricevendo poi nuova luce dalla formulazione dell’equazione di risonanza nucleare da part

Multichannel quantum mechanics as a Hamiltonian phase flow

Autor: Ugo Fano, John L. Bohn

Publikováno v: Physical Review A. 50:2893-2898

We cast the quantum mechanics of multichannel systems in the broader mathematical framework of Hamiltonian phase space flow. This flow results from symplectic transformations that preserve antisymmetric products, namely, metric relations among altern

A common mechanism of collective phenomena

Autor: Ugo Fano

Publikováno v: Reviews of Modern Physics. 64:313-319

A common thread is followed through diverse phenomena: Weak interactions lock seemingly independent variables into a collective state of enhanced or depressed energy. A rather novel perspective is thus afforded on superconductivity and on nuclear and
