Identity in Physics: Properties, Statistics and the (Non-)Individuality of Quantum Particles

- Philosophy
- 2012

The issue whether or not the most fundamental entities described by non-relativistic quantum mechanics are individual objects is of interest for both philosophers and metaphyiscians, and has received…

Identity in Physics: Statistics and the (Non-)Individuality of Quantum Particles

- Philosophy
- 2010

This paper discusses the issue of the identity and individuality (or lack thereof) of quantum mechanical particles. It first reconstructs, on the basis of the extant literature, a general argument in…

Entities, Identity and the Formal Structure of Quantum Mechanics

- Physics
- 2012

The concept of individuality in quantum mechanics shows radical differences from the one used in classical physics. In particular, it is not possible to consider the fundamental particles described…

Physics, inconsistency, and quasi-truth

- PhilosophySynthese
- 2014

This work defends a pluralistic view of the philosophy of science, grounded on the existence of inconsistencies and on quasi-truth, and studies the nature of informal inconsistency in physics, focusing mainly on the foundations of quantum theory.

Studies in History and Philosophy of Modern Physics

- Philosophy
- 2009

This paper puts forward the hypothesis that the distinctive features of quantum statistics are exclusively determined by the nature of the properties it describes. In particular, all statistically…

From Current Algebra to Quantum Chromodynamics: A Case for Structural Realism

- Physics

1. Introduction 2. The rise of current algebra (CA) 3. Sum rules 4. Saturation and closure 5. Scaling 6. Theorizations of scaling 7. The advent of quantum chromodynamics (QCD) 8. Early justifications…

The relational ontology of contemporary physics

- Physics, Philosophy
- 2022

Quantum theory can be understood as pointing to an ontology of relations. I observe that this reading of quantum mechanics is supported by the ubiquity of relationality in contemporary fundamental…

Some aspectos of quantum physics

- Physics
- 2007

I discuss some questions of quantum physics, for instance the validity and limitations of the basic language of set theory to deal with problems related to elementary particles. I also present a…

OF WEIGHTING AND COUNTING: STATISTICS AND ONTOLOGY IN THE OLD QUANTUM THEORY

- Philosophy

This tension traverses the entire history of quantum statistics, and this article tries to unfold the main fracture lines. It is often stated that quantum statistics deals with indistinguishable…

A formal framework for the study of the notion of undefined particle number in quantum mechanics

- Physics, PhilosophySynthese
- 2014

A set theoretical framework for the description of undefined particle number states in quantum mechanics which provides a precise logical meaning for this notion and is capable of representing quantum superpositions.

A Discussion on Particle Number and Quantum Indistinguishability

- Physics
- 2007

The concept of individuality in quantum mechanics shows radical differences from the concept of individuality in classical physics, as E. Schrödinger pointed out in the early steps of the theory.…

Discerning Fermions

We demonstrate that the quantum-mechanical description of composite physical systems of an arbitrary number of similar fermions in all their admissible states, mixed or pure, for all…

Q-spaces and the Foundations of Quantum Mechanics

- Philosophy
- 2008

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…

A Metaphysics for Scientific Realism: Knowing the Unobservable

Part I. Scientific Realism Today: 1. Realism and antirealism, metaphysics and empiricism 2. Selective scepticism: entity realism, structural realism, semirealism 3. Properties, particulars and…

Scientific Structuralism: On The Identity and Diversity of Objects in a Structure

- Philosophy
- 2007

The identity and diversity of individual objects may be grounded or ungrounded, and intrinsic or contextual. Intrinsic individuation can be grounded in haecceities, or absolute discernibility.…

The Indispensability of Mathematics

- Philosophy
- 2001

Looks at the Quine–Putnam indispensability argument in the philosophy of mathematics. This argument urges us to place mathematical entities on the same ontological footing as other theoretical…

The First Edition

Until the 1960s, academic criminology was confined by decades of repression in a theoretical and political cage. Obviously, given the repression, one could hardly have expected things to turn out…
