Emergence and identity of quantum particles
1History and Philosophy of Science, Utrecht University, Utrecht,The Netherlands.
Summary
Classical physics views particles as fundamental, but quantum mechanics challenges this. An Alternative View proposes particles emerge with distinct identities, differing from the standard quantum mechanical perspective.
Area of Science:
- Quantum physics
- Philosophy of science
- Foundations of physics
Background:
- Classical physics posits particles as fundamental constituents.
- Relativistic quantum field theory (RQFT) challenges the fundamental nature of particles.
- Quantum mechanics presents particles as 'entities without identity' in the standard view.
Purpose of the Study:
- To challenge the 'Received View' of quantum particles.
- To propose and defend an 'Alternative View' (AV) emphasizing particle emergence.
- To explore the conditions under which quantum particles gain distinguishable identities.
Main Methods:
- Conceptual analysis of particle identity in quantum mechanics.
- Comparison of the 'Received View' and the proposed 'Alternative View'.
- Examination of physical and logical/conceptual implications.
Main Results:
- The 'Received View' assumes particle emergence is complete in quantum mechanics, leading to indistinguishable particles.
- The 'Alternative View' (AV) argues particle emergence is not complete in quantum mechanics.
- AV posits that under specific conditions, quantum particles emerge as distinguishable individuals with unique identities.
Conclusions:
- The standard view of quantum particles as inherently indistinguishable is questioned.
- The Alternative View offers a framework where particles can possess distinct physical identities.
- Revisiting particle emergence in quantum mechanics is crucial for understanding individuality in physics.

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.
