Large-uncertainty intelligent states for angular momentum and angle [PDF]
The equality in the uncertainty principle for linear momentum and position is obtained for states which also minimize the uncertainty product. However, in the uncertainty relation for angular momentum and angular position both sides of the inequality are

Rotation of electromagnetic fields and the nature of optical angular momentum [PDF]
The association of spin and orbital angular momenta of light with its polarization and helical phase fronts is now well established. The problems in linking this with electromagnetic theory, as expressed in Maxwell's equations, are rather less well known.

Orbital angular momentum: origins, behavior and applications [PDF]
As they travel through space, some light beams rotate. Such light beams have angular momentum. There are two particularly important ways in which a light beam can rotate: if every polarization vector rotates, the light has spin; if the phase structure ...

Osteologia craniana de Penelope superciliaris Temminck, 1815 (Galliformes: Cracidae)
Penelope superciliaris é endêmica da região Neotropical, pertencente à subfamília Penelopinae, inserida na família Cracidae. Sua posição taxonômica ainda é controversa em relação às espécies congêneres, bem como entre os gêneros pertencentes a esta ...

Stratosphere-troposphere exchange: An angular momentum perspective [PDF]
The exchange of axial angular momentum (AM) between stratosphere and troposphere forms an important part of stratosphere–troposphere exchange (STE). Data are used to quantify the related fluxes through an idealized tropopause for specific flux events ...
