Unified treatment of the total angular momentum of single photons via generalized quantum observables
Mario Motta, Giacomo Guarnieri, Ludovico Lanz +1
In this paper we provide a consistent framework to address the notorious decomposition of the single-photon total angular momentum (TAM) into a spin (SAM) and an orbital (OAM) comp…
Single-Photon Observables and Preparation Uncertainty Relations
G. Guarnieri, M. Motta, L. Lanz
We propose a procedure for defining all single-photon observables in terms of Positive-Operator Valued Measures (POVMs), in particular spin and position. We identify the suppressio…
Quantum theory: the role of microsystems and macrosystems
L. Lanz, B. Vacchini, O. Melsheimer
We stress the notion of statistical experiment, which is mandatory for quantum mechanics, and recall Ludwig's foundation of quantum mechanics, which provides the most general frame…
Decoherence Versus the Idealization of Microsystems as Correlation Carriers Between Macrosystems
Ludovico Lanz, Bassano Vacchini
It is argued that the appropriate framework to describe a microsystem as a correlation carrier between a source and a detector is non-equilibrium statistical mechanics for the comp…
Time scales in quantum mechanics by a scattering map
L. Lanz, B. Vacchini
Inside quantum mechanics the problem of decoherence for an isolated, finite system is linked to a coarse-grained description of its dynamics.
Description of isolated macroscopic systems inside quantum mechanics
L. Lanz, O. Melsheimer, B. Vacchini
For an isolated macrosystem classical state parameters are introduced inside a quantum mechanical treatment. By a suitable mathematical representation of the actual preparat…
