Matterwave's latest activity
-
Matterwave replied to the thread Undergrad Spatial separation of entangled particles implies physical separability?.By "independence" here, do you mean statistical independence of measurements? In analyzing an argument such as EPRs, it is best if we... -
Matterwave reacted to PeterDonis's post in the thread High School Einstein equations don't work at large scale? with
Like.
More precisely, if we just use the matter we can actually see as the source in the Einstein Field Equation, the model does not match the... -
Matterwave reacted to PeterDonis's post in the thread Graduate Entanglement swapping and Bohmian mechanics with Like.
The Hilbert space doesn't change just because you make a measurement or perform a unitary operation. The full Hilbert space describing...

Matterwave replied to the thread Undergrad Spatial separation of entangled particles implies physical separability?.The EPR paper is always worth a (re)read 😉. It is a delightful paper, though it has its faults.

Got it. Thanks Bill.

Matterwave replied to the thread Undergrad Spatial separation of entangled particles implies physical separability?.Just the time order of things as the paper presents it. T is not the time of the measurement, it's the final time after which the...
-
Matterwave replied to the thread Undergrad Spatial separation of entangled particles implies physical separability?.Not for the EPR state. It is still an entangled state and not a product state. When EPR says (something like) "after T, the two...
-
Matterwave replied to the thread Undergrad Spatial separation of entangled particles implies physical separability?.EPR made an implicit assumption in their argument that indeed you can stop the two particles from interacting with each other...

Peter beat me to the punch - he often does o:)o:)o:)o:)o:) Thanks Bill

You do get 2, but you can't split the state up into a product of two states each with a value 1 for the number operator. That's what it...

Matterwave replied to the thread Undergrad Spatial separation of entangled particles implies physical separability?.Hmmm, what are you counting as a "single excitation" here? If you hit the state with the number operator, you don't get 2?
-
Matterwave replied to the thread Undergrad Spatial separation of entangled particles implies physical separability?.Are you reading the EPR paper? It was an implicit assumption of EPR that sufficient spatial separation implies non-interaction. They...

Matterwave reacted to Paul Colby's post in the thread Graduate Best visualization of SO(3) with Like.
Visualize as a manifold seems to be all you consider. There’s the algebraic aspect of ##SO(3)## as well.
-
To me, the best way to visualize ##\text{SO}(3)## is as a rigid body with a fixed point. In particular by examining its motion through...

How about Bloch sphere for qubit? Perhaps you want more than that.
