We make a proposal for a Gedanken experiment, based on the Aharonov-Bohm effect, how to measure in principle the zig-zagness of the trajectory of propagation (abberation from its classical trajectory) of a massive particle in quantum mechanics. Experiment I is conceived to show that contributions from quantum paths abberating from the classical trajectory are directly observable. Experiment II ...

_ _. We argue that th&crossing (CPT) y s mmetry of relativistic quantum mechanics requires that both the Coulombic and the Newtonian force between pairs of particles will reverse when one is replaced by its anti-particle. For consistency, this requires a theory in which both the equivalence principle and gauge invariance are abandoned. Thus whether ant,i-hydrogen " falls " up or down will provi...

Local hidden variable theories are known to be inconsistent with quantum mechanics at the microscopic level, from the Bell inequalities @1#. Experimental tests at this level have decided in favor of quantum mechanics @2#, although there are still some experimental problems with low detection efficiency. The situation is different as particle numbers increase. There are no macroscopic tests of q...

In this paper we study the classical Hilbert space introduced by Koopman and von Neumann in their operatorial formulation of classical mechanics. In particular we show that the states of this Hilbert space do not spread, differently than what happens in quantum mechanics. The role of the phases associated to these classical ”wave functions” is analyzed in details. In this framework we also perf...

Contact mechanics is related to the deformation study of solids that meet each other at one or more points. The physical and mathematical formulation of the problem is established upon the mechanics of materials and continuum mechanics and focuses on computations involving bodies with different characteristics in static or dynamic contact. Contact mechanics gives essential information for the s...

Two physical experiments have captured the paradoxical nature of quantum mechanics in an elementary yet essentially complete way: the double-slit experiment and the EPR experiment. Few experiments in the history of science have generated so many ferocious debates, prompted so many controversial interpretations and at the end left us with such a deep feeling of discomfort with the current state ...

We describe an explicit statistical model of local hidden variables that reproduces the predictions quantum mechanics for ideal Franson experiment and sheds light on physical mechanisms might be involved in actual experiment. The crux our is spontaneous breaking time-translation gauge symmetry by configurations pairs photons locked time energy experiment, which acquire a non-zero geometric phas...

An experiment is described which proves, using single photons only, that the standard hidden variables assumptions (commonly used to derive Bell inequalities) are inconsistent with quantum mechanics. The analysis is very simple and transparent.
