Orbital Angular Momentum

2023
Abstract In this chapter we introduce the concept of orbital angular momentum into the mathematical language of quantum mechanics. We discuss the commutation relations of the corresponding operators and their roles as generators of rotations in the context of the theory of Lie groups and Lie algebras, focusing on the three-dimensional ...

Controlling neutron orbital angular momentum

Nature, 2015
The quantized orbital angular momentum (OAM) of photons offers an additional degree of freedom and topological protection from noise. Photonic OAM states have therefore been exploited in various applications ranging from studies of quantum entanglement and quantum information science to imaging.

Light’s Orbital Angular Momentum

Physics Today, 2004
The realization that light beams can have quantized orbital angular momentum in addition to spin angular momentum has led, in recent years, to novel experiments in quantum mechanics and new methods for manipulating ...

Partonic orbital angular momentum

AIP Conference Proceedings, 2013
Ji's decomposition of nucleon spin is used and the orbital angular momentum of quarks and gluon are calculated. We have utilized the so called valon model description of the nucleon in the next to leading order. It is found that the average orbital angular momentum of quarks is positive, but small, whereas that of gluon is negative and large ...

Optical solitons carrying orbital angular momentum

Physical Review Letters, 1997
We predict a new kind of ring-profile solitary wave in nonlinear optical media, with finite orbital angular momentum. During propagation these fragment into fundamental solitons. Like free Newtonian particles, these fly off tangential to the ring, vividly demonstrating conservation of orbital angular momentum in soliton motion.

Hybrid entanglement carrying orbital angular momentum

Science Bulletin
Hybrid continuous-variable (CV) and discrete-variable (DV) entanglement is an essential quantum resource of hybrid quantum information processing, which enables one to overcome the intrinsic limitations of CV and DV quantum protocols. Besides CV and DV quantum variables, introducing more degrees of freedom provides a feasible approach to increase the ...

Orbital angular momentum entanglement

2012
Entanglement in higher dimensions is an attractive concept that is a chal- lenge to realise experimentally. To this end, the entanglement of the orbital angular momentum (OAM) of photons holds promise. The OAM state-space is discrete and theoretically unbounded. In the work that follows, we investi- gate various aspects of OAM entanglement. We show how

Special Nature of Orbital Angular Momentum

American Journal of Physics, 1963
The properties of orbital angular momentum operators are examined within the framework of the formal theory of angular momentum. It is demonstrated that the occurrence of only integral quantum numbers in the orbital theory is a consequence of the particular form of the orbital operators. Single-valuedness of the eigenfunctions need not be postulated.
