Some conjectures about the mechanism of poltergeist phenomenon (2008)
Poltergeist accounts concern at least four kinds of strange spontaneous manifestations, such as burning of materials, failures of electric equipments, rapping noises and movements of objects. A...
Are elementary particles point-like objects? (2007)
Brovetto, P., Maxia, V., Salis, M.
Simple arguments based on uncertainty principle and Dirac's equation are examined which show that electron behaves either as a point-like charge or as an extended distribution according as high- or...
FURTHER MEASUREMENTS OF NaCl THERMOLUMINESCENCE PARAMETERS AND RELATED TOPICS. (2006)

Some remarks about mass and Zitterbewegung substructure of electron (2005)
Brovetto, P., Maxia, V., Salis, M.
It is shown that the electron Zitterbewegung, that is, the high-frequency microscopic oscillatory motion of electron about its centre of mass, originates a spatial distribution of charge. This allows...
A theory about high-temperature superconductivity (2005)
We deal with a model for high-temperature superconductivity which maintains that in cuprates electrons running in the copper oxide layers, found in lattice of these materials, form spin-singlet bonds...
