About the Notion of Truth in the Decoherent Histories Approach: a reply to Griffiths
Angelo Bassi, GianCarlo Ghirardi
Griffiths claims that the ``single family rule'', a basic postulate of the decoherent histories approach, rules out our requirement that any decoherent history has a unique truth v…
Quantization and Time
A. A. Abrikosov, E. Gozzi
Starting from a functional formulation of classical mechanics, we show how to perform its quantization by freezing to zero two Grassmannian partners of time.
Decoherent Histories and Realism
Angelo Bassi, GianCarlo Ghirardi
We reconsider the Decoherent Histories approach to Quantum Mechanics and we analyze some problems related to its interpretation which, according to us, have not been adequately cla…
Particle Propagator in Elementary Quantum Mechanics: a New Path Integral Derivation
S. Ansoldi, A. Aurilia, E. Spallucci
This paper suggests a new way to compute the path integral for simple quantum mechanical systems. The new algorithm originated from previous research in string theory. However, its…
Complete positivity and neutron interferometry
F. Benatti, R. Floreanini
We analyze the dynamics of neutron beams in interferometry experiments using quantum dynamical semigroups. We show that these experiments could provide stringent limits on the non-…
