# Identical Particles in Quantum Mechanics

@article{Lubberdink2009IdenticalPI, title={Identical Particles in Quantum Mechanics}, author={Andrea Lubberdink}, journal={arXiv: General Physics}, year={2009} }

If, in a system of identical particles, the one particle state is defined by the partial trace to one of the component spaces of the total Hilbert space, then all one particle states are identical. The particles are indistinguishable. This is often thought to be a typical quantum mechanical phenomenon. I will show however that an analogous procedure to define particle states exists in classical mechanics, which results in classical indistinguishable identical particles. From this analogy it…

Identical Quantum Particles as Distinguishable Objects

- Physics

According to classical physics particles are basic building blocks of the world. These classical particles are distinguishable objects, individuated by unique combinations of physical properties. By…

Identical Quantum Particles, Entanglement, and Individuality

The premises of the standard view of particle indistinguishability are analyzed, an alternative that avoids these and similar problems is discussed, and this alternative approach connects to recent discussions in quantum information theory.

How Classical Particles Emerge From the Quantum World

The symmetrization postulates of quantum mechanics (symmetry for bosons, antisymmetry for fermions) are usually taken to entail that quantum particles of the same kind (e.g., electrons) are all in…

The Gibbs Paradox Revisited

- Physics, Economics

The Gibbs paradox has frequently been interpreted as a sign that particles of the same kind are fundamentally indistinguishable; and that quantum mechanics, with its identical fermions and bosons, is…

The Identity of Indiscernibles

- Philosophy

The principle of the identity of indiscernibles would seem, in the forms in which it is usually stated, to be at best contingently true. It does not appear that even Leibniz held it to be logically…
