Quantum Monte Carlo Study of electrons in low dimensions
A. Malatesta, Gaetano Senatore
We report on a diffusion Monte Carlo investigation of model electron systems in low dimensions, which should be relevant to the physics of systems obtainable nowadays in semiconduc…
From Large N Matrices to the Noncommutative Torus
G. Landi, F. Lizzi, R. J. Szabo
We describe how and to what extent the noncommutative two-torus can be approximated by a tower of finite-dimensional matrix geometries. The approximation is carried out for both ir…
Direct CP-violation as a test of quantum mechanics
Fabio Benatti, Roberto Floreanini
Direct CP-violating effects in the neutral kaon system result in violations of certain Bell-like inequalities. The new experimental results on the determination of the phenomenolog…
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…
