Can the Many-Worlds Interpretation be probed in Psychology?

Heinrich Päs (Technische Universität Dortmund) A minimal approach to the measurement problem and the quantum-to-classical transition assumes a universally valid quantum formalism, i.e. unitary time evolution governed by a Schrödinger-type equation. As had been pointed out long ago, in this view the measurement process can be described by decoherence which results in a "Many-Worlds" or "Many-Minds" scenario according to Everett and Zeh. A silent... Read more →

Quantum measurements as weighted symmetry breaking processes: the hidden measurement perspective

The purpose of the present note is twofold. Firstly, we highlight the similarities between the ontologies of Kastner's possibilist transactional interpretation (PTI) of quantum mechanics - an extension of Cramer's transactional interpretation - and the authors' hidden-measurement interpretation (HMI). Secondly, we observe that although a weighted symmetry breaking (WSB) process was proposed in the PTI, to explain the actualization of incipient transactions,... 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 →

Event ontology in quantum mechanics and downward causation

Rodolfo Gambini (Instituto de Fsica, Facultad de Ciencias) and Jorge Pullin (Louisiana State University) We show that several interpretations of quantum mechanics admit an ontology of objects and events. This ontology reduces the breach between mind and matter. When humans act, their actions do not appear explainable in mechanical terms but through mental activity: motives, desires or needs that propel them to action. These... Read more →

Thought experiment of the reality of matter wave

Takeshi Yamaguchi (Tokyo Institute of Technology) A thought experiment regarding the light-wave diffraction by a matter-wave lattice is proposed. Matter-wave diffraction by an optical-lattice is already a well-established experimental technology, therefore, its symmetrical phenomenon, i.e., light-wave diffraction by a matter-wave lattice, does not seem to be unlikely. If the diffracted light could be observed, it would suggest the presence of... Read more →

Analysis of Everett’s quantum interpretation from the point of view of a Bohmian

Aurelien Drezet (CNRS-University Joseph Fourier) In this article we discuss and compare the many worlds interpretation (MWI) proposed by Everett and others and the pilot wave interpretation (PWI) of de Broglie and Bohm. We focus our study on two fundamental issues: i) the ontological framework definition, and ii) the meaning of probability (i.e., the Born rule). We show that PWI... Read more →

Randomness in physics revisited

Michail Zak, (Jet Propulsion Laboratory California Institute of Technology) There has been proven that mathematical origins of randomness in quantum and Newtonian physics are coming from the same source that is dynamical instability. However in Newtonian physics this instability is measured by positive finite Liapunov exponents averaged over infinite time period, while in quantum physics the instability is accompanied by...

Reply to Gillis's "On the Analysis of Bell's 1964 Paper by Wiseman, Cavalcanti, and Rieffel" (Open Review Paper)

Howard M. Wiseman, Eleanor G. Rieffel and Eric Cavalcanti We address Gillis' recent criticism of a series of papers (by different combinations of the present authors) on formulations of Bell's theorem. Those papers intended to address an unfortunate gap of communication between two broad camps in the quantum foundations community that we identify as ``operationalists'' and ``realists''. Here, we once again urge... Read more →

Concerning Quadratic Interaction in the Quantum Cheshire Cat Experiment

We believe the weak interaction of the quantum Cheshire Cat experiment must be linear if the weak values are to support the quantum Cheshire Cat interpretation, i.e., that a particle and one of its properties are spatially separated. For example, even though Denkmayr et al. measured the proper weak values for quantum Cheshire Cat in their neutron interferometry experiment, they did so using a quadratic...
