It is shown that although the de Broglie-Bohm quantum theory of motion is equivalent to standard quantum mechanics when averages of dynamical variables are taken over a Gibbs ensemble of Bohmian trajectories, the equivalence breaks down for ensembles built over clearly separated short intervals of time in special multi-particle systems. This feature is… (More)

An experiment is suggested that is capable of distinguishing between the de Broglie-Bohm theory and standard quantum mechanics.

A basic and one of the oldest socio-cognitive domains of the human species is music. Listening to music regularly helps keep the neurons and synapses more active. Neurological studies have identified that music is a valuable tool for evaluating the brain system. It has been observed that different parts of the brain are involved in processing music. They… (More)

It is shown that superluminal optical signaling is possible without violating Lorentz invariance and causality via tunneling through photonic band gaps in inhomogeneous dielectrics of a special kind.

When these are substituted into his equation (17), the right hand side of his equation (18) vanishes. What Marchildon’s calculations have, in fact, established is that the assumption of translation invariance (Fraunhoffer diffraction and plane waves) imposed by me in my papers are sufficient but not necessary to obtain the basic result, namely that the… (More)

In spite of its popularity, it has not been possible to vindicate the conventional wisdom that classical mechanics is a limiting case of quantum mechanics. The purpose of the present paper is to offer an alternative point of view in which both quantum and classical mechanics emerge as limiting cases of a new mechanics we call ‘mesomechanics’. PACS no.… (More)

The mutual interaction of a relativistic particle and gravitoelectromagnetism (GEM) is studied both classically and quantum theoretically.

Arguments are presented to show that in the case of entangled systems there are certain difficulties in implementing the usual Bohmian interpretation of the wave function in a straightforward manner. Specific examples are given. The three basic prescriptions of standard Bohmian quantum theory [1] are: (i) take the wave function ψ to be a solution of the… (More)

A simple non-interferometric “quantum interrogation” method is proposed which uses evanescent wave sensing with frustrated total internal reflection on a surface. The simple method has the advantage over the original interferometric Elitzur-Vaidman method of being able to detect objects that are neither black nor non-diffracting and that are such that they… (More)
