Synchronization of thermal Clocks and entropic Corrections of Gravity

Andreas Schlatter There are so called MOND corrections to the general relativistic laws of gravity, able to explain phenomena like the rotation of large spiral galaxies or gravitational lensing by certain galaxy clusters. We show that these corrections can be derived in the framework of synchronizing thermal clocks. We develop a general formula, which reproduces the deep MOND correction at large scales and...

Addendum to Quantum Wave Function Collapse of a System Having Three anti Commuting Elements

Abstract : We indicate a new way in the solution of the problem of the quantum measurement . In past papers we used the well-known formalism of the density matrix using an algebraic approach in a two states quantum spin system S, considering the particular case of three anticommuting elements. We demonstrated that, during the wave collapse, we have a... Read more →

Geometry of quantum correlations in space-time. (arXiv:1711.05955v1 [quant-ph])  quant-ph updates on arXiv.org on 2017-11-17 2:42am GMT Authors: Zhikuan Zhao, Robert Pisarczyk, Jayne Thompson, Mile Gu, Vlatko Vedral, Joseph F. Fitzsimons The traditional formalism of non-relativistic quantum theory allows the state of a quantum system to extend across space, but only restricts it to a single instant in time, leading to distinction between theoretical treatments of spatial...

Particle or wave: there is no evidence of single photon delayed choice

Michael Devereux (Los Alamos National Laboratory) Wheeler supposed that the way in which a single photon is measured in the present could determine how it had behaved in the past. He named such retrocausation delayed choice. Over the last forty years many experimentalists have claimed to have observed single-photon delayed choice. Recently, however, researchers have proven that the quantum wavefunction of a single photon... Read more →
