Sentence examples for by a selection rule from inspiring English sources

The discontinuous change is explained by a selection rule for the recombination: The optical transition conserves the orbital angular momentum in two-dimensional systems [11].

In the case of exciton recombination, the final state is always the vacuum state of the quantum dot, and the peak position is continuous as a function of Φ, as seen in Figure 4a (The recombination of exciton with the angular momentum L ≠ 0 is forbidden by a selection rule.

The fiber diffraction analysis indicated that the B15D fibril was composed of a double helix defined by the selection rule l = n + 7m (where l is even, and n and m are any integers), and having a 199-Å period and pitch, 28-Å rise per unit, and 10-Å radius.

This helical model is equivalent to a reverse-handed, single helix with half the period and defined by the selection rule l = −3n + 7m (where l is any integer).

By the selection rule, excitons with the angular momentum L ≠ 0 should be dark.

PSNR degradation which is caused by the leader selection rule is compensated by the SVC with UEP block and the Raptor code block.

In addition the historian may remark that the existence of other frameworks in no way invalidates a discussion based on the quasiclassical one that lies behind the ordinary language discussion of cats, which is distinguished by its utility and not by some framework selection rule, see subsection 11.3.
