Orbital angular momentum of entangled counterpropagating photons.
We elucidate the paraxial orbital angular momentum of entangled photon pairs generated by spontaneous parametric downconversion in different noncollinear geometries in which the entangled photons counterpropagate. We find, in particular, the orbital angular momentum of entangled pairs generated in transverse-emitting configurations, in which none of the known rules for selecting orbital angular...
متن کاملArbitrarily tunable orbital angular momentum of photons
Orbital angular momentum (OAM) of photons, as a new fundamental degree of freedom, has excited a great diversity of interest, because of a variety of emerging applications. Arbitrarily tunable OAM has gained much attention, but its creation remains still a tremendous challenge. We demonstrate the realization of well-controlled arbitrarily tunable OAM in both theory and experiment. We present th...
متن کاملCorrected Version Transverse Angular Momentum Relations
As discussed in my Pedagogical lecture: We need expression for the non-forward matrix elements of the energy momentum tensor t . Although t transforms as a tensor under Lorentz transformations, its non-forward matrix elements do not. Erroneously assuming that they do led to the incorrect expression for the angular momentum expectation value for a transversely polarized nucleon: ⟨Ji⟩incorrect = ...
متن کاملQuantum field theory of photons with orbital angular momentum
A quantum-field-theory approach is put forward to generalize the concept of classical spatial light beams carrying orbital angular momentum to the single-photon level. This quantization framework is carried out both in the paraxial and nonparaxial regimes. Upon extension to the optical phase space, closed-form expressions are found for a photon Wigner representation describing transformations o...
متن کاملEntanglement of Orbital Angular Momentum States of Photons
Entanglement contains one of the most interesting features of quantum mechanics, often named quantum non-locality[1, 2]. This means entangled states are not separable regardless of the spatial separation of their components. Measurement results on one particle of a two-particle entangled state define the state of the other particle instantaneously with neither particle enjoying its own well-def...
