Hello everyone, does anybody of you know, whether there are some publications/blog entries/ideas/anything on possibilities of experimental verification/falsification of Loop Quantum Gravity at collider experiments? I know, there are predictions that can be tested with astrophysical...

Thanks, DrChinese, that was a great answer! Now I see, where I am wrong. Thanks again!

I cannot tell it from the list. But I can arrange the measurement in such a way that in some frame of references the two measurement do happen simultaneously. In any other frame of reference one measurement would happen after the another and, of course, "destroy" the results of the first...

Exactly my point. But if we perform the two measurements simultaneously, what happens then?

Hello, could someone please tell what mistake I am doing by the following gedankenexeperiment. Imagine two Stern-Gerlach-like devices that measure spin projections of some spin-1/2 particles. Right between them in the middle there is some trap (I don't care about technical details)...

Well, the basic idea of the Lie groups and lie algebras is the following. A Lie group G is a group, whose elements can be written as exp(i * ak Xk), where k runs from 1 to N and over k is summed (Einstein summation convention), ak are some real-valued parameters and Xk are some linearly...

Hello, I hope it's not the wrong forum for my question which is the following: Is there some list of Lie algebras, whose adjoint representations have the same dimension as their basic representation (like, e.g., this is the case for so(3))? How can one find such Lie algebras? Could you...
