Clarification of the transverse orbital angular momentum of spatiotemporal optical vortices
Miguel A. Porras
Advances in the generation and the application of spatiotemporal optical vortices (STOV) are proceeding fast, but fundamental aspects of their nature remain obscure. Phys. Rev. A 1…
Comment on "Spatiotemporal torquing of light"
Miguel A. Porras
The recent paper Phys. Rev. X. 14, 011031 (https://doi.org/10.48550/arXiv.2307.01019) includes an appendix that casts doubts on the validity the theory of the transverse orbital an…
Comment on "Mode Structure and Orbital Angular Momentum of Spatiotemporal Optical Vortex (STOV) Pulses"
Miguel A. Porras
We report a mathematical error and a misinterpretation in arXiv:2103.03263v4 [Phys. Rev. Lett. 127, 193901 (2021)] that has led to a debate about the nature of the transverse orbit…
Control of vortex orientation of ultrashort optical pulses using spatial chirp
Miguel A. Porras, Spencer W. Jolly
Introducing a spatial chirp into a pulse with a longitudinal vortex, such as a standard pulsed Laguerre-Gauss beam, results in a vortex pulse with an arbitrary orientation of the l…
Teleportation of a quantum particle in a potential via quantum Zeno dynamics
Miguel A. Porras, Miguel Casado-Álvaro, Isabel Gonzalo
We report on the possibility of teleportation of a quantum particle, a distinctly different phenomenon from the teleportation of a quantum state through entanglement. With the firs…
Stabilization of vortex beams in Kerr media by nonlinear absorption
Miguel A. Porras, Márcio Carvalho, Hervé Leblond +1
We elaborate a new solution for the problem of stable propagation of transversely localized vortex beams in homogeneous optical media with self-focusing Kerr nonlinearity. Stationa…
