Times Two: The Tenses of Linear and Collapse Dynamics in Relational Quantum Mechanics [PDF]

, 2008
The nature and topology of time remains an open question in philosophy, both tensed and tenseless concepts of time appear to have merit. A concept of time including both kinds of time evolution of physical systems in quantum mechanics subsumes the ...

Relational Motivation for Conformal Operator Ordering in Quantum Cosmology

, 2009
Operator-ordering in quantum cosmology is a major as-yet unsettled ambiguity with not only formal but also physical consequences. We determine the Lagrangian origin of the conformal invariance that underlies the conformal operator-ordering choice in ...

SMALLEST RELATIONAL MECHANICS MODEL OF QUANTUM COSMOLOGY [PDF]

The Twelfth Marcel Grossmann Meeting, 2012
Relational particle mechanics are models in which there is, overall, no time, position, orientation (nor, sometimes, scale). They are useful for whole-universe modelling - the setting for quantum cosmology. This note concerns 3 particles in 1d in shape-scale split variables.

A link between static and dynamical perturbation theory

New Journal of Physics
Dynamics, the physical change in time and a pillar of natural sciences, can be regarded as an emergent phenomenon when the system of interest is part of a larger, static one.

THE FAULT IN US: ETHICS, INFINITY, AND CELESTIAL BODIES

Zygon, 2016
Catherine Keller's Cloud of the Impossible knits together process theology and relational ontology with quantum mechanics. In quantum physics, she finds a new resource for undoing the architecture of classical metaphysics and its location of autonomous ...

Representation and Perspective in Science

Principia: An International Journal of Epistemology, 2007
The world science describes tends to have a very strange look. We can’t see atoms or force fields, nor are they imaginable within visualizable categories, so neither can we even imagine what the world must be like according to recent physical theories ...

Integrated Information in Relational Quantum Dynamics (RQD)

Applied Sciences
We introduce a quantum integrated-information measure Φ for multipartite states within the Relational Quantum Dynamics (RQD) framework. Φ(ρ) is defined as the minimum quantum Jensen–Shannon distance between an n-partite density operator ρ and any product
