Quantum theory without measurement or state reduction problems
... Macroscopic systems are not, under ordinary circumstances, isolated. They cannot be isolated if we can see them. They interact with their own radiation field and that of other objects. They absorb cosmic background radiation photons. Due to their extremely dense energy spectra, they are coupled with ...

The quantum Heisenberg group H(1)q
... The Hopf algebra H( 1) 4 just defined is clearly different from the algebra of the q-deformed creation and annihilation operators used in the Jordan-Schwinger map of SU (2) 4;4 as it has been shown in Ref. 5 the right quantum structure for these q-deformed operators is B( O( 1) 9. This fact is relat ...

The measure of existence of a quantum world and the Sleeping
... The illusion of probability follows from the identity between the quantum state of the hypothetical Collapse Universe and the quantum state of the corresponding world in the MWI Universe. An observer in a Collapse Universe, performing a sequence of experiments, will have the same memories as an obs ...

... was developed in a systematic manner largely by Emil Wolf. After the invention of intensity interferometry by Hanbury Brown and Twiss in 1956, it became clear that it was necessary to go beyond the two-point amplitude correlation function (adequate to describe Young-type interference phenomena) to h ...

Arrows of Time

Then we could argue about whether both of those predecessors really existed (a reversed MW picture) or whethe ...

algebraic quantization and t

The main purpose of the quantization method (yet another one!) presented in this Letter is to explain this very linkage in a transparent algebraic language, providing a direct connection between the existence of inequivalent quantizations, which we identify with superselection sectors, and the emerg ...
