No place for particles in relativistic quantum theories?
localizable particles relativity and quantum theory
2008/4/22
Several recent arguments purport to show that there can be no relativistic, quantum-mechanical theory of localizable particles and, thus, that relativity and quantum mechanics can be reconciled only i...
This paper is about the metaphysical debate whether objects persist over time by the selfsame object existing at different times (nowadays called `endurance' by metaphysicians), or by different tempor...
Particles vs. Structures: Weak Ontic Structuralism
particles structures ontic structuralism
2008/4/22
In modern physics the notion of structure can be treated as an extension of the notion of law of nature. French and Ladyman’s view concerning the ontological priority of structures over objects is con...
Particles, Objects, and Physics
indistinguishability indiscernibility permutation symmetry
2008/4/22
This thesis analyses the ontological nature of quantum particles. In it I argue that quantum particles, despite their indistinguishability, are objects in much the same way as classical particles. Thi...
In his paper ``What is Structural Realism?'' James Ladyman drew a distinction between epistemological structural realism and metaphysical (or ontic) structural realism. He also drew a suggestive analo...
Quantum mechanics and discontinuous motion of particles
interpretation of quantum mechanics particles
2008/4/22
We discuss a new realistic interpretation of quantum mechanics based on discontinuous motion of particles. The historical and logical basis of discontinuous motion of particles is given. It proves tha...
The domains of quantum theory and general relativity overlap in situations where quantum mechanical effects cannot be ignored. In order to deal with this overlap of theoretical domains, there has been...
What quantum mechanics describes is discontinuous motion of particles
interpretation of quantum mechanics discontinuous motion
2008/4/18
We present a theory of discontinuous motion of particles in continuous space-time. We show that the simplest nonrelativistic evolution equation of such motion is just the Schroedinger equation in quan...
Individual particles, properties and quantum statistics
quantum statistics individuality emergent relations
2008/4/14
Although there have been several attempts to resist this conclusion, it is commonly held that the peculiar statistical behaviour of quantum particles is due to their non-individuality. In this paper, ...
Identical Quantum Particles and Weak Discernibility
Quantum statistics indistinguishable particles weak indiscernibility
2008/4/14
We examine a recent argument that ``identical'' quantum particles with an anti-symmetric state (fermions) are weaklydiscernible objects, just like irreflexively related ordinary objects in situations ...
Identical Particles and Weak Discernibility
Identical particles Leibniz's Principle Weak Discernibility
2008/4/14
Saunders has recently claimed that ``identical quantum particles'' with an anti-symmetric state (fermions) are weakly discernible objects, just like irreflexively related ordinary objects in situation...
Derivation of the Symmetry Postulates for Identical Particles from Pilot-Wave Theories
identical particles Bohm theory stochastic mechanics
2008/4/11
The symmetries of the wavefunction for identical particles, including anyons, are given a rigorous non-relativistic generalisation within pilot-wave formulations of quantum mechanics. In particular, p...
Cosmology, Particles, and the Unity of Science
Cosmology Particle Physics Quantum Field Theory
2008/4/10
During the last three decades, there has been a growing
realization among physicists and cosmologists that the relation between particle physics and cosmology may constitute yet another successful ex...
Particle indistinguishability has always been considered a purely quantum mechanical concept. In parallel, indistinguishable particles have been thought to be entities that are not properly speaking o...
Are All Particles Real?
Bohmian mechanics ontology
2008/4/10
In Bohmian mechanics elementary particles exist objectively, as point particles moving according to a law determined by a wavefunction. In this context, questions as to whether the particles of a cert...
