Photodetectors are fermionic. Detection happens via electrons transitioning in silicon or being freed from a photocathode. A many-body...

"Branches always present" only requires unitary evolution plus that the Dirac matter field is physical. That's shared by MWI, Bohmian...

This framing only assumes decoherence (which every interpretation accepts) plus that the observer's own matter current is physical...

The wavefunction doesn't "collapse", instead the observer's Dirac current (the physical matter current) becomes entangled with the...

1. observer = anything that can provide a frame of reference sitting in spacetime (more precisely, anything with a well-defined...

The Schrödinger picture in QFT is Lorentz-covariant. Tomonaga (1946) and Schwinger (1948) generalized the functional Schrödinger...

Perhaps there was a misunderstanding. I wasn't claiming that mathematical objects are reality. I was noting that since waves and...

Theories of physics study physical invariants in reality. There has to be some mapping between the mathematical objects a theory uses...

Operators are mathematical objects, no? Are you describing more of an instrumentalist reading of QFT?

Sure, my point is that the canonical wave-particle duality picture is challenged on this reading of Barandes' work. QFT already treats...

One way to read this argument is that particles are emergent instead of fundamental. Barandes shows that if we take particles to be...

The derivation assumes the Bekenstein-Hawking entropy-area formula S=A/(4Gℏ)S=A/(4Gℏ), which is itself a semi-classical result. It comes...

Standard QFT refers to Dirac fields as "matter fields", which is also what I am referring to, but using matter-wave field wrt to...

Hello, I work in the matter-wave-realism tradition (de Broglie, Bohm, Schrödinger's original reading), and my focus is the relationship...
