... GHZ and Bell’s theorem In 1935, after failing for years to defeat the uncertainty principle, Einstein argued that quantum mechanics is incomplete. Note that [x, ˆp] ≠ 0, but [x2–x1, pˆ 2+pˆ 1] = [x2, pˆ 2] – [x1, pˆ1] = 0. That means we can measure the distance between two particles and their total ...

He asserted that the “emergence of objects” from quantum grounds through self-organization should be taken for granted, rather than using formally basic elementary quantum mechanic for highly complex systems in a rather vague way. These questions are also significant for the assumptions of no-go the ...

... Quantum Theory just seems too weird to believe. Particles can be in more than one place at a time. And they don't exist until you measure them. Spookier still, they can even stay in touch when they are separated by great distances. Einstein thought this was all a bit much, believing it to be evidenc ...

Quantum Wires and Quantum Point Contacts
... Such an equilibrium is achieved only at the distances larger than the electron mean free path. Thus, the dissipation takes place in the leads close to the contacts. What we have calculated is the total resistance of the device, which can be understood as an intrinsic contact resistance. Quantum wire ...

... the other hand, when T ≫ TF and Maxwell-Boltzmann statistics apply, quantum spin effects are negligible, being a small perturbation [of O(µB B/T ) ≪ 1] to the standard Vlasov kinetics (as also stated in [2]). At high temperatures, Larmor moments µL = T /B dominate over spin moments (µL ≫ µB ). Also, ...
