| 1 | Entanglement beating in free space through spin–orbit coupling显示文摘It is well known that the entanglement of a quantum state is invariant under local unitary transformations.This rule dictates,for example,that the entanglement of internal degrees of freedom of a photon remains invariant during free-space propagation.Here,we outline a scenario in which this paradigm does not hold.Using local Bell states engineered from classical vector vortex beams with non-separable degrees of freedom,the so-called classically entangled states,we demonstrate that the entanglement evolves during propagation,oscillating between maximally entangled(purely vector)and product states(purely scalar).We outline the spin–orbit interaction behind these novel propagation dynamics and confirm the results experimentally,demonstrating spin–orbit coupling in paraxial beams.This demonstration highlights a hitherto unnoticed property of classical entanglement and simultaneously offers a device for the on-demand delivery of vector states to targets,for example,for dynamic laser materials processing,switchable resolution within stimulated emission depletion(STED)systems,and a tractor beam for entanglement. | Eileen Otte Carmelo Rosales-Guzmán Bienvenu Ndagano Cornelia Denz Andrew Forbes | 2018 | Light(Science & Applications)2018，7，1： | 5 |

| 3 | Pseudospin-2 in photonic chiral borophene显示文摘Pseudospin is an angular momentum degree of freedom introduced in analogy to the real electron spin in the effective massless Dirac-like equation used to describe wave evolution at conical intersections such as the Dirac cones of graphene.Here,we study a photonic implementation of a chiral borophene allotrope hosting a pseudospin-2 conical intersection in its energy-momentum spectrum.The presence of this fivefold spectral degeneracy gives rise to quasiparticles with pseudospin up to±2.We report on conical diffraction and pseudospin-orbit interaction of light in photonic chiral borophene,which,as a result of topological charge conversion,leads to the generation of highly charged optical phase vortices. | PHILIP MENZ HAISSAM HANAFI DANIEL LEYKAM JÖRG IMBROCK CORNELIA DENZ | 2023 | Photonics Research2023，11，5： | 0 |
