What exactly are the "empty" branches of the wave function in Bohmian mechanics?

24. What exactly are the "empty" branches of the wave function in Bohmian mechanics? This series is aimed at answering FAQs about Bohmian mechanics and is mainly intended for students. The text is available at http://www.mathematik.uni-muenchen.de/~bohmmech/BohmHome/files/Frequently_Asked_Question…

Is Bohmian mechanics not much more complicated than the easy formalism of quantum mechanics?

18. Is Bohmian mechanics not much more complicated than the easy formalism and the easy to apply rules of quantum mechanics? This series is aimed at answering FAQs about Bohmian mechanics and is mainly intended for students. The text is available at http://www.mathematik.uni-muenchen.de/~bohmmech/…

What is a measurement in Bohmian mechanics?

7. In quantum mechanics the notion of a measurement seems to be central. What is a measurement in Bohmian mechanics? Are there special rules for the prediction of the outcomes of measurements derived from the Bohmian framework? This series is aimed at answering FAQs about Bohmian mechanics and is…

Isn't the Heisenberg uncertainty relation in contradiction to the existence of trajectories?

This series is aimed at answering FAQs about Bohmian mechanics and is mainly intended for students. The text is available at http://www.mathematik.uni-muenchen.de/~bohmmech/BohmHome/files/Frequently_Asked_Questions_about_Bohmian_Mechanics.pdf By Christian Beck, Robert Grummt, Florian Hoffmann, Sör…

Is Bohmian mechanics not a hidden variable theory disproved by the no-go theorems?

11. Is Bohmian mechanics not a hidden variable theory? There are various no-go theorems, ruling out hidden variable approaches. Does not for example Bell's Theorem or the Kochen-Specker Theorem prove Bohmian mechanics wrong? This series is aimed at answering FAQs about Bohmian mechanics and is mai…

Do we see the Bohmian trajectory of a single particle in a cloud chamber?

17. One of the main devices for measuring particle trajectories are cloud chambers and the like. Do we see the Bohmian trajectory of a single particle there? This series is aimed at answering FAQs about Bohmian mechanics and is mainly intended for students. The text is available at http://www.math…

FAQ about Bohmian mechanics – Introduction

This series is aimed at answering FAQs about Bohmian mechanics and is mainly intended for students.

How does one describe measurements in Bohmian mechanics?

8. Every measurable physical quantity should be represented by a self-adjoint operator. These operators are part of the axioms of quantum mechanics, though they don't seem to appear in Bohmian mechanics. How does one then describe measurements in Bohmian mechanics? This series is aimed at answerin…

What is the collapse in Bohmian mechanics?

9. In standard quantum mechanics the wave function of a system collapses upon observation. I always thought the collapse of the wave function was something essential. In Bohmian mechanics the wave function always evolves according to Schrödinger's equation and never collapses. How can that be? What…

Bohmian mechanics is deterministic, how does randomness come about then?

21. What's the role of randomness in Bohmian mechanics? Quantum mechanics is a probabilistic theory while Bohmian mechanics is deterministic, how does randomness come about in Bohmian mechanics? This series is aimed at answering FAQs about Bohmian mechanics and is mainly intended for students. Th…
