Morbert's latest activity
-
Morbert replied to the thread Graduate Universal quantum physics.Ok, so long as it's understood that the selection of a decoherent set amounts to the identification of a set relevant to us at the time... -
Morbert replied to the thread Graduate Universal quantum physics.A quick comment about the decoherent histories section: "To give decoherent histories meaning in the context of an unobserved universe...

Morbert reacted to A. Neumaier's post in the thread Undergrad Sean Carroll's description of the Many Worlds interpretation with
Like.
I gave references in my paper here. -
Morbert replied to the thread Undergrad Sean Carroll's description of the Many Worlds interpretation.What's nice about DH is it's an interpretation of any quantum theory. I.e. any theory with a non-commutative algebra of observables...
-
Morbert replied to the thread High School Interesting paper on QM in Scientific American.I mean plainly that the physical system of a human observer can always be placed on the "observed" side of the divide, as explained by...

Morbert replied to the thread High School Interesting paper on QM in Scientific American."Inserting the observer into the Schrödinger equation, it seems, allows transformative new perspectives on century-old questions." Von...

Morbert replied to the thread Graduate Understanding Barandes' microscopic theory of causality.The latter Zeilinger paper maps nicely onto section VIII of Barandes's new prospects paper. We have 7 subsystems: particles 1,2,3,4...

Morbert replied to the thread Graduate Understanding Barandes' microscopic theory of causality.Some links that might be relevant. https://arxiv.org/abs/2402.16935 In section VIII the formalism is applied to a basic EPR scenario...
-
Morbert replied to the thread Graduate Understanding Barandes' microscopic theory of causality.I just don't see the interpretational challenge. At each time the system is in a definite configuration, with a likelihood given by the...
-
Morbert replied to the thread Graduate Understanding Barandes' microscopic theory of causality.The configuration space isn't Markovian or non-Markovian. It's the ordinary configuration space of classical physics.
-
Morbert replied to the thread Graduate Understanding Barandes' microscopic theory of causality.You just read off the ontology from the configuration space on the stochastic side of the correspondence.
-
Morbert replied to the thread Graduate Understanding Barandes' microscopic theory of causality.Objective collapse and no-objective-collapse theories disagree about what happens in the realm of superobservers. Barandes's...
-
Morbert replied to the thread Graduate Understanding Barandes' microscopic theory of causality.Note that causal locality here refers to Barandes's principle, not Bell's principle of local causality.
-
Morbert replied to the thread Graduate Understanding Barandes' microscopic theory of causality.Yes. The question is whether the Bell sense actually captures the notion of nonlocal influence if dynamics are non-Markovian. From "La...

Morbert replied to the thread Graduate Understanding Barandes' microscopic theory of causality.@Sambuco said it well here: In Barandes's reformulation, the derived conditional probabilities can pertain directly to microphysical...
