A. Orefice, present on ResearcheGate.net web site
Associate Professor of Physics (from 1967 to 2007) at the University of Milan and Theoretician (from 1967 to 1997) at the Institute of Plasma Physics (IFP-CNR) of Milan (Italy), A.O. participated (from 1983 to 1993) in the ECW Plasma Heating Program of the Joint European Torus of Culham (Oxfordshire,UK), under a number of Contracts: JET Contract JB2/9005 (1983); JET Contract JTA/9001 (1986); JET Contract JT6/9004 (1988); JET Contract JJ8/9009 (1990).
A.O. mainy operated in the field of THERMONUCLEAR PLASMA PHYSICS (which he quit in 1997) and of WAVE MECHANICS (where he's still active nowadays, 2015).

Thermonuclear Plasma Physics

In connection with the the Jet Joint Undertaking collaboration, A.O. has extensively developed the Relativistic Theory of Electron Cyclotron Electromagnetic Waves (ECEW) in Fusion Plasmas, discovering the exact recurrence expressions holding for the relativistic dispersion relation both of Maxwellian and non-Maxwellian (supra-thermal) electron distributions, and passing then to the general quasi-linear theory of plasma absorption and emission in toroidal plasmas.
The theory was successively extended to the ECEW Polarization Evolution in Sheared Thermonuclear Plasmas and to the quasi-optical propagation of Gaussian beams of ECEW in Tokamak Plasmas [1-13].

Wave Mechanics

Passing then to the field of theoretical Wave Mechanics, A.O. extended the mathematical methods previously contrived for the quasi-optical theory of Gaussian beams of ECEW to the determination (within the same quasi-optical approximation) of the electron trajectories associated with the time-independent Schrödinger equation [14].
He considered, in the following, the case of the Mössbauer effect, arriving at a new and exact integral formulation of the Debye-Waller relation [15-19], passing finally (after having discovered the general possibility of describing any kind of mono-chromatic wave-like features in terms of ray-trajectories) to show that for monochromatic matter waves the usual constraints of the Uncertainty Principle may be eluded, allowing an exact (both classical and relativistic) formulation of the particle trajectories, avoiding the statistical concepts involved both by the Copenhagen and Bohmian approaches [20-22].
