Quantum Fields on Noncommutative Spacetimes: gy ?
... Abstract. In the present work we review the twisted field construction of quantum field theory on noncommutative spacetimes based on twisted Poincaré invariance. We present the latest development in the field, in particular the notion of equivalence of such quantum field theories on a noncommutativ ...

Optical and Magnetic Properties of Copper(II) compounds.
... restrictions defining the pairs of energy levels between which such transitions can occur are called electron dipole selection rules.29 These rules, which can be explained in terms of symmetry of the wave-functions, are true only in the first approximation. The forbidden transitions are often observed ...

The Quark model
... Quark quantum numbers The quark model is the follow-up to the Eightfold Way classification scheme (proposed by Murray Gell-Mann and Yuval Ne'eman ) The Eightfold Way may be understood as a consequence of flavor symmetries between various kinds of quarks. Since the strong nuclear force affects quark ...

... for the case of K = k0 , R is not zero, but unity. This is because for this particular choice, the denominator of R is also zero. Therefore, one can not determine R only from the numerator. The limit of R at k = k0 is identified to be unity by applying the L’Hopital’s rule. One could interpret this ...

Three Myths About Time Reversal in Quantum Theory 1. Introduction
... 2. First Stage: Time reversal is unitary or antiunitary 2.1. Wigner’s theorem. Wigner’s theorem is one of the central results of modern quantum theory, first presented by Wigner (1931). The theorem is often glossed as showing that any transformation A : H → H on a separable Hilbert space that deserv ...
