??? How can the observer's brain solve the Schrödinger equation in real time?

One could argue that if the electron does not exist between measurements, then it cannot be described by a state or wave-function (or...

It would mean that the Schrödinger equation (or whatever differential equation the state is assumed to satisfy) breaks down somewhere.

More interesting (and applicable to QFT) is the book A. Hobson, Fields and Their Quanta, 2024. It also gives a realist account...

See, e.g., the discussion in the last two sections of D. Wallace, The quantum theory of fields, and his Reading List in Philosophy of...

I tried to define everything that is not in typical textbooks. For a single field ##\phi##, the N-point function is simply the map (and...

A (classical or quantum) particle is a quantum field concentrated at each time in a small region of space. I tried to avoid the use of...

It is finished for submission, and I put it online to get some early feedback before actually submitting it (in a few weeks). So the...

Based on the thermal interpretation, I developed a quantum version of the classical, mechanical universe suggested by Laplace over 200...

Possibly of interest: Albert, David Z. (2025) NOTES ON JACOB BARANDES’ VERSION OF QUANTUM MECHANICS. - Preprint...

But his book is nearly as far as possible from the consensus textbook orthodoxy; see the last paragraph of p.20 in Beck's paper!

Orthodoxy is what is (by most textbooks) imparted to students when they have to learn quantum mechanics. That automatically excludes...

By the paper cited, we now know much better than we used to know....

Good theories (of which good models are anintegral part) have a high explanatory power, revealed by appropriate computations (that...
