High Orbital Angular Momentum Harmonic Generation [PDF]
Physical Review Letters, 2016 We identify and explore a high orbital angular momentum (OAM) harmonics generation and amplification mechanism that manipulates the OAM independently of any other laser property, by preserving the initial laser wavelength, through stimulated Raman backscattering in a plasma.

Spin-constrained orbital-angular-momentum control in high-harmonic generation
Physical Review Research, 2019 The interplay between spin and orbital angular momentum in the up-conversion process allows us to control the macroscopic wave front of high harmonics by manipulating the microscopic polarizations of the driving field.

Nested SU(2) symmetry of photonic orbital angular momentum
Frontiers in Physics, 2023 The polarization state is described by a quantum mechanical two-level system, which is known as special unitary group of degree 2 [SU(2)]. Polarization is attributed to an internal spin degree of freedom inherent to photons, while photons also possess an

Orbital angular momentum photonic quantum interface [PDF]
Light: Science & Applications, 2016 AbstractLight-carrying orbital angular momentum (OAM) has great potential in enhancing the information channel capacity in both classical and quantum optical communications. Long distance optical communication requires the wavelengths of light are situated in the low-loss communication windows, but most quantum memories currently being developed for ...

Mapping the transverse spin sum rule in position space
Physics Letters BWe discuss in detail the relativistic spatial distribution of transverse angular momentum, including both orbital and intrinsic spin contributions. Using the quantum phase-space formalism, we begin with the definition of the three-dimensional spatial ...

Orbital-angular-momentum entanglement in turbulence [PDF]
Physical Review A, 2013 The turbulence induced decay of orbital angular momentum (OAM) entanglement between two photons is investigated numerically and experimentally. To compare our results with previous work, we simulate the turbulent atmosphere with a single phase screen based on the Kolmogorov theory of turbulence.
