Extreme-ultraviolet (XUV) sources including high-harmonic generation (HHG), free-electron lasers (FELs), soft-X-ray and laser-driven plasmas are widely used for applications ranging from femtochemistry attosecond science to coherent diffractive imaging EUV (or XUV) lithography. The bandwidth of the XUV light emitted by these reflects process used. Whereas lasers1 seeded FELs2 typically has a re...

As a promising avenue to obtain new extreme ultraviolet light source and detect electronic properties, high-harmonic generation (HHG) has been actively developed in both theory experiment. In solids lacking inversion symmetry, when electrons undergo nonadiabatic transition, directional charge shift occurs is characterized by vector, which measures the real-space of photoexcited electron hole. F...

Using machine learning, we explore the utility of various deep neural networks (NN) when applied to high harmonic generation (HHG) scenarios. First, train NNs predict time-dependent dipole and spectra HHG emission from reduced-dimensionality models di- triatomic systems based on sets randomly generated parameters (laser pulse intensity, internuclear distance, molecular orientation). These netwo...

ABSTRACT The purpose of this study was to investigate whether intravenous crotalphine produces significant sedation, as well physiological changes, in healthy standing horses. Six mares, aged 8 years and weighing 415kg underwent three different treatments a crossover design: TA (acepromazine: 50μg.kg-1), TC (crotalphine: 0.01μg.kg-1) TX (xylazine: 1000μg.kg-1), intravenously. At various time po...

Three fast generators of direct photons in the central rapidity region of high-energy heavy-ion collisions have been presented The generator of prompt photons is based on a tabulation of p + p(p̄) data and binary scaling. Two generators of thermal direct photons, for hot hadron gas (HHG) and quark-gluon plasma (QGP) scenarios, assume the 1+1 Bjorken hydrodynamics. SPS and RHIC data can be fitted...

While multicore architectures are becoming usual on desktop machines, supercomputers are approaching million cores. The amount of memory and compute power on current clusters enable us e.g. to obtain a resolution of in excess (10 000)=10 degrees of freedom. However, on the downside we are forced to partition our domain into extremely many sub-problems. Portions of the algorithm that do not perm...

We examine a scheme for a Free Electron Laser (FEL) harmonic amplifier seeded by a 30-nm wavelength signal produced using a process of High-order Harmonic Generation (HHG). The seed is first amplified in an optical klystron from 100 kW to 30 MW using a 1 GeV electron beam and then is used for an energy modulation of electrons in the downstream undulator. Subsequently, a 100MW level of radiation...

Quantum control using femtosecond laser pulses has recently induced a revolution in photochemistry. Not only the nuclear motion within a molecule can be observed time resolved, but it can be controlled. The necessary pulse shaping techniques, however, have mainly restricted this control so far to visible and near IR absorptions. Fundamental compounds of organic chemistry and biochemistry such a...

In transition metal dichalcogenides (TMDCs), charge carriers have spin, pseudospin, and valley degrees of freedom associated with magnetic moments. The monolayers bilayers the TMDCs, in particular, MoS2, lead to strong couplings between spin pseudospin effects. This feature has drawn attention TMDCs for their potential use advanced tech devices. Meanwhile, high-order harmonic generation (HHG) r...
