Geometric Control of Cat States in High Harmonic Generation
Arti Gaharwar, Rocío Borrego-Varillas, Marcelo F. Ciappina +6
High-harmonic generation (HHG) provides a powerful platform for exploring the interaction between intense laser fields and matter on ultrafast timescales. Beyond its conventional d…
Topological phase transitions via attosecond x-ray absorption spectroscopy
Juan F. P. Mosquera, Giovanni Cistaro, Mikhail Malakhov +6
We present a numerical experiment that demonstrates the possibility to capture topological phase transitions via an x-ray absorption spectroscopy scheme. We consider a Chern insula…
Chiral topological light for detecting robust enantio-sensitive observables
Nicola Mayer, David Ayuso, Piero Decleva +4
The topological response of matter to electromagnetic fields is a property in high demand in materials design and metrology due to its robustness against noise and decoherence, sti…
Conservation of a Half-Integer Angular Momentum in Nonlinear Optics with a Polarization Möbius Strip
Martin Luttmann, Mekha Vimal, Matthieu Guer +5
Symmetries and conservation laws of energy, linear momentum and angular momentum play a central role in physics, in particular in nonlinear optics. Recently, light fields with non…
Enantiosensitive steering of free-induction decay
Margarita Khokhlova, Emilio Pisanty, Serguei Patchkovskii +2
Chiral discrimination, a problem of vital importance, has recently become an emerging frontier in ultrafast physics, with remarkable progress achieved in multiphoton and strong-fie…
Quantum-Optical Spectrometry in Relativistic Laser-Plasma Interactions Using the High-Harmonic Generation Process: A Proposal
Theocharis Lamprou, Rodrigo Lopez-Martens, Stefan Haessler +8
Quantum-optical spectrometry is a recently developed shot-to-shot photon correlation-based method, namely using a quantum spectrometer (QS), that has been used to reveal the quantu…
Optical polarization skyrmionic fields in free space
Rodrigo Gutiérrez-Cuevas, Emilio Pisanty
We construct optical beams in free space with robust skyrmionic structures in their polarization fields, both in the electric spin vector for near-circular fields and in the polari…
Generation of optical Schrödinger cat states in intense laser-matter interactions
Maciej Lewenstein, Marcelo F. Ciappina, Emilio Pisanty +4
The physics of intense laser-matter interactions is described by treating the light pulses classically, anticipating no need to access optical measurements beyond the classical lim…
Suppression of individual peaks in two-colour high harmonic generation
Sambit Mitra, Shubhadeep Biswas, Johannes Schötz +11
This work investigates the suppression of individual harmonics, simultaneously affecting specific even and odd orders in the high-harmonic spectra generated by strongly tailored, t…
Light with a self-torque: extreme-ultraviolet beams with time-varying orbital angular momentum
Laura Rego, Kevin M. Dorney, Nathan J. Brooks +11
Twisted light fields carrying orbital angular momentum (OAM) provide powerful capabilities for applications in optical communications, microscopy, quantum optics and microparticle…
Knotting fractional-order knots with the polarization state of light
Emilio Pisanty, Gerard J. Machado, Verónica Vicuña-Hernández +4
The fundamental polarization singularities of monochromatic light are normally associated with invariance under coordinated rotations: symmetry operations that rotate the spatial d…
