Nonseparability, Classical and Quantum
Electromagnetism holonomy gauge theories separability
2009/9/17
This paper examines the implications of the holonomy interpretation of classical electromagnetism. As has been argued by Richard Healey and Gordon Belot, classical electromagnetism on this interpretat...
The Quantum Liar Experiment in Cramer's Transactional Interpretation
transactional interpretation quantum paradoxes entanglement time symmetry
2009/9/16
Cramer's Transactional Interpretation (TI) is applied to the ``Quantum Liar Experiment'' (QLE). It is shown how some apparently paradoxical features can be explained naturally, albeit nonlocally (sinc...
Quantum Gravity: Motivations and Alternatives
Quantum Gravity Covariant Quantization Canonical Quantization
2009/9/16
The mutual conceptual incompatibility between General Relativity and Quantum Mechanics / Quantum Field Theory is generally seen as the most essential motivation for the development of a theory of Quan...
Entanglement, Upper Probabilities and Decoherence in Quantum Mechanics
Decoherence upper probabilities Bell states
2009/9/16
Computation of decay time for entangled quantum systems is an important aspect of decoherence theories. Here we explore this topic from the standpoint of computing the decay time to the existence of a...
Quantum physics, causation, and the GRW dynamics
causal properties classical properties direction of time
2009/9/16
The paper makes a case for there being causation in the form of causal properties in the domain of fundamental physics. That case is built on an interpretation of quantum theory in terms of state redu...

2009/6/24
Cramer's Transactional Interpretation (TI) is applied to the ``Quantum Liar Experiment'' (QLE). It is shown how some apparently paradoxical features can be explained naturally, albeit nonlocally (sinc...
Coexistence of several interpretations of quantum mechanics and the fruitfulness of scientific works
Fruitfulness of works re-using works quantum mechanics coexistence of interpretations
2009/6/24
The coexistence of several interpretations of one theory is considered through the example of non-relativistic quantum mechanics. The problem considered is whether physicists manage to work properly i...
Quantum Mechanics on Spacetime I: Spacetime State Realism
spacetime state realism wave-function realism quantum ontology non-separability narratability
2009/6/19
What ontology does realism about the quantum state suggest? The main extant view in contemporary philosophy of physics is wave-function realism. We elaborate the sense in which wave-function realism d...
Qeauty and the Books: A Response to Lewis's Quantum Sleeping Beauty Problem
Quantum Sleeping Beauty Sleeping Beauty
2009/6/11
In his 2007 paper “Quantum Sleeping Beauty”, Peter Lewis poses a problem for appeals to subjective probability in the Everett interpretation of quantum mechanics. Lewis’s argument hinges on parallels ...
The Consistent Histories Interpretation of Quantum Mechanics
quantum mechanics physics interpretation consistent histories
2009/6/11
The consistent histories reformulation of quantum mechanics was developed by Robert Griffiths, given a formal logical systematization by Roland Omn\`{e}s, and under the label `decoherent histories', w...
Many-Worlds Interpretations Can Not Imply ‘Quantum Immortality’
quantum suicide immortality Everett
2009/4/10
The fallacy that the many worlds interpretation (MWI) of quantum mechanics implies certain survival in quantum-Russian-roulette-like situations (the ‘Quantum Suicide’ (QS) thought experiment) has beco...
Logical Aspects of Quantum（Non-）Individuality
individuality in quantum physics relational indiscernibility individuals
2009/4/2
In this paper I consider some logical and mathematical aspects of the discussion of the identity and individuality of quantum entities. I shall point out that for some aspects of the discussion, the l...
Quantum Gravity: Has Spacetime Quantum Properties?
Quantum Gravity Quantum Spacetime Emergent Gravity Emergent Spacetime
2009/4/1
The conceptual incompatibility between General Relativity and Quantum Mechanics is generally seen as a sufficient motivation for the development of a theory of Quantum Gravity. If - so a typical argum...
Observations on Unstable Quantons, Hyperplane Dependence and Quantum Fields
decay theory relativistic lifetime dilation hyperplane dependence quantum fields
2009/3/27
There is persistent heterodoxy in the physics literature concerning the proper treatment of those quantons that are unstable against spontaneous decay. Following a brief litany of this heterodoxy, I d...
Intuitionistic quantum logic of an n-level system
quantum logic topos theory intuitionistic
2009/3/25
A decade ago, Isham and Butterfield proposed a topos theoretic approach to quantum mechanics, which meanwhile has been extended by Doering and Isham so as to provide a new mathematical foundation for ...
