Photon bunching in high-harmonic emission controlled by quantum light [PDF]

open access: yesNature Photonics
Attosecond spectroscopy comprises several techniques to probe matter using electrons and photons. One frontier of attosecond methods is to reveal complex phenomena arising from quantum-mechanical correlations in the matter system, in the photon fields ...

Bivariate stochastic model of current harmonic analysis in the low voltage distribution grid [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2021
This paper presents a bottom-up bivariate analysis approach to estimate current harmonics by taking account of network and load variations. The current harmonics assessment in the presence of existing and future nonlinear loads is vital to study their ...

High-order Harmonic Field Retrieval in Ethylene [PDF]

open access: yesEPJ Web of Conferences, 2019
The XUV field emitted by impulsively aligned ethylene molecules during high-order harmonic generation is retrieved as a function of molecular orientation. The results can be ascribed to multielectron contributions to the harmonic emission.

Automatic Identification of Different Types of Consumer Configurations by Using Harmonic Current Measurements

open access: yesApplied Sciences, 2021
Power quality (PQ) is an increasing concern in the distribution networks of modern industrialized countries. The PQ monitoring activities of distribution system operators (DSO), and consequently the amount of PQ measurement data, continuously increase ...

Relativistic short-pulse high harmonic generation at 1.3 and 2.1 μm wavelengths

open access: yesNew Journal of Physics, 2019
While nearly all investigations of high order harmonic generation with relativistically intense laser pulses have taken place at 800 or 1053 nm, very few experimental studies have been done at other wavelengths.

Observation of recollision-based high-harmonic generation in liquid isopropanol and the role of electron scattering

open access: yesPhysical Review Research, 2023
We report extreme-ultraviolet high-harmonic generation (HHG) from liquid isopropanol, extending up to 50 eV, when using 1800-nm carrier envelope phase stable pulses of 1.8 cycles with intensities below the laser breakdown threshold.
