Quantum Mechanics II SS 2014
... In the special case of a central potential, V (r), the orbital angular momentum, L, particle is a constant of motion. Therefore, there exist stationary states with well-defined ~ 2 and Lz . And, as we found in angular momentum, i.e., eigenstates common to H, L QM I, the Schrödinger equation of a sp ...

A mechanistic classical laboratory situation violating the Bell
... Bell has put forward this locality hypothesis having in mind the entity consisting of two spin-1/2 particles in the singlet spin state. Why do people find this locality hypothesis 'natural' for this entity? Because they imagine the entity to be an entity consisting of two spin-1/2 particles located ...

Expectation values of descendent fields in the Bullough
... In a 2-D integrable quantum field theory (QFT) which can be realized as a conformal field theory (CFT) perturbed by some relevant operator, it is well-known that any correlation function of local fields Oa (x) in the short-distance limit can be reduced down to one-point functions < Oa′ (x) > by succ ...

Notice also that the interaction between the atoms is due to the polarization of the electronic cloud, and as consequence the interaction between 4 He-4 He, 3 He-3 He, and 4 He-3 He pairs can be considered to be the same. Keeping this in mind, it is ...

Loop Quantum Gravity and Effective Matter Theories

The second kind of divergency, worst in nature, comes from the whole series expansion. This last one is not cured even using a renorm ...
