... Two important remarks 1. The same Lagrangian must be used for calculating the classical trajectories and the classical action along these trajectories. If two different Lagrangians are used, the principle of least action is violated. The phase shift is not correct, so that the wave function no lon ...

A Signed Particle Formulation of Non
... In this paper, we introduce a new formulation of quantum mechanics in terms of signed classical field-less particles. This suggested theory is based on a generalization and a novel physical interpretation of the mathematical Wigner Monte Carlo method [8] which is able to simulate the time-dependent ...

An Introduction to Quantum Fluid of Light
... The first sum is relative to the kinetic energy of each particle and their interaction with a confinement potential necessary to trap and cool bosons. The second sum describes boson-boson interactions. We make the hypothesis that at T = 0 each particle is in the same state : Ψ(~r1 , ..., ~rN , t) = ...

Bohr–Einstein debates
The Bohr–Einstein debates were a series of public disputes about quantum mechanics between Albert Einstein and Niels Bohr. Their debates are remembered because of their importance to the philosophy of science. An account of the debates was written by Bohr in an article titled ""Discussions with Einsteinon Epistemological Problems in Atomic Physics"". Despite their differences of opinion regarding quantum mechanics, Bohr and Einstein had a mutual admiration that was to last the rest of their lives.The debates represent one of the highest points of scientific research in the first half of the twentieth century because it called attention to an element of quantum theory, quantum non-locality, which is absolutely central to our modern understanding of the physical world. The consensus view of professional physicists has been that Bohr proved victorious, and definitively established the fundamental probabilistic character of quantum measurement.
