Quantum Probability and Decision Theory, Revisited
Quantum Mechanics Everett Interpretation
2008/4/22
An extended analysis is given of the program, originally suggested by Deutsch, of solving the probability problem in the Everett interpretation by means of decision theory. Deutsch's own proof is disc...
This paper reviews four attempts throughout the history of quantum mechanics to explicitly employ dispositional notions in order to solve the quantum paradoxes, namely: Margenau’s latencies, Heisenber...
Quantum Puzzles in the Metaworld of Heisenberg, Clauser, and Horne
Clauser-Horne inequalities Heisenberg uncertainty principle
2008/4/22
This paper follows up on a recent pre-print (Durham [2005]) by first deriving a set theoretic relationship between the generalized uncertainty relations and the Clauser-Horne inequalities. The physica...
The Sleeping Beauty paradox in epistemology and the many-worlds interpretation of quantum mechanics both raise problems concerning subjective probability assignments. Furthermore, there are striking p...
Sortal predicates have been associated with a counting process, which acts as a
criterion of identity for the individuals they correctly apply to. We discuss in
what sense certain types of predicate...
Quantum superposition principle justified in a new non-Aristotelian finitary logic
Quantum superposition entanglement non-classical logic
2008/4/22
In the proposed non-Aristotelian finitary logic (NAFL), truths for formal propositions can exist only with respect to axiomatic theories, essentially as temporary axiomatic declarations in the human m...
Quantum Time Arrows, Semigroups and Time-Reversal in Scattering
Irreversibility time arrows rigged Hilbert space
2008/4/22
Two approaches toward the arrow of time for scattering processes have been proposed in rigged Hilbert space quantum mechanics. One, due to Arno Bohm, involves preparations and registrations in laborat...
Our aim in this paper is to take quite seriously Heinz
Post's claim that the non-individuality and the indiscernibility of
quantum objects should be introduced right at the start, and
not made a po...
We consider realism as a purely metaphysical regulative principle, not subject to scientific proof. In this sense, realism can be maintained in quantum mechanics, provided one does not claim that matt...
Explaining the Unobserved: Why Quantum Theory Ain't Only About Information
Quantum information Collapse theories Crucial experiments
2008/4/22
A remarkable theorem by Clifton, Bub and Halvorson (2003) (CBH) characterizes quantum theory in terms of information--theoretic principles. According to Bub (2004, 2005) the philosophical significance...
Reality, measurement and locality in Quantum Field Theory
Quantum Field Theory Standard Model Correlations Locality
2008/4/22
It is currently believed that the local causality of Quantum Field
Theory (QFT) is destroyed by the measurement process. This belief
is also based on the Einstein-Podolsky-Rosen (EPR) paradox and on...
Recent Conceptual Consequences of Loop Quantum Gravity. Part III: A Postscript On Time.
Natural Philosophy Philosophy of Science Quantum Gravity
2008/4/22
With a view to the results discussed in the first two parts of this paper, the concept of time is revisited oncemore and chosen as an example in order to demonstrate the meaning of fundamental in both...
Recent Conceptual Consequences of Loop Quantum Gravity. Part II: Holistic Aspects.
Natural Philosophy Philosophy of Science Quantum Gravity
2008/4/22
Based on the foundational aspects which have been discussed as consequences of ongoing research on loop quantum gravity in the first part of this paper, the holistic aspects of the latter are discusse...
Recent Conceptual Consequences of Loop Quantum Gravity. Part I: Foundational Aspects.
Natural Philosophy Philosophy of Science Quantum Gravity
2008/4/22
Conceptual consequences of recent results in loop quantum gravity are collected and discussed here in view of their implications for a modern philosophy of science which is mainly understood as one th...
In a recent paper, David Albert has suggested that no quantum theory can yield a description of the world unfolding in Minkowski spacetime. This conclusion is premature; a natural extension of Stein's...
