Resolving the Problem of Definite Outcomes of Measurements

Art Hobson (University of Arkansas) The entangled "Schrodinger's cat state" of a quantum and its measurement apparatus is not a paradoxical superposition of states but is instead a non-paradoxical superposition of nonlocal coherent correlations between states: An un-decayed nucleus is correlated with a live cat, and a decayed nucleus is correlated with a dead cat. This elucidation of entanglement is demonstrated by quantum-theoretical analysis and... Read more →

On Participatory Realism

Christopher A. Fuchs To appear in "Information & Interaction: Eddington, Wheeler, and the Limits of Knowledge", edited by Ian T. Durham and Dean Rickles In the Philosophical Investigations, Ludwig Wittgenstein wrote, " 'I' is not the name of a person, nor 'here' of a place, .... But they are connected with names. ... [And] it is characteristic of physics not... Read more →

Violation of the Born Rule: Implications for Macroscopic Fields.

ABSTRACT. It is shown that violation of the Born Rule leads to a breakdown of the correspondence between the quantum electromagnetic field and its classical counterpart. Specifically, the relationship of the quantum coherent state to the  classical electromagnetic field turns out to imply that if the Born Rule were violated, this could result in apparent deviations from the energy conservation...

Non-Relativistic Limit of the Dirac Equation

Muhammad Adeel Ajaib (California Polytechnic State University) We show that the first order form of the Schrodinger equation proposed in [1] can be obtained from the Dirac equation in the non-relativistic limit. We also show that the Pauli Hamiltonian is obtained from this equation by requiring local gauge invariance. In addition, we study the problem of a spin up particle... Read more →
