Abstract We report a coherent layer-by-layer build-up of high-order harmonic generation (HHG) in artificially stacked transition metal dichalcogenides (TMDC) crystals their various stacking configurations.

Abstract Rabbitfish Siganus canaliculatus was the first marine teleost demonstrated to have ability biosynthesize C 20–22 long‐chain polyunsaturated fatty acid (LC‐PUFA) from 18 PUFA precursors, which is generally absent or low in teleosts. Thus, understanding molecular basis of LC‐PUFA biosynthesis rabbitfish will contribute efforts aimed at optimizing teleosts, especially species. In present study, importance transcription factors liver X receptor (Lxr) and sterol regulatory...
Excitons in two-dimensional transition metal dichalcogenides have a valley degree of freedom that can be optically manipulated for quantum information processing. Here, we integrate MoS2 monolayers with achiral silicon disk array metasurfaces to enhance and control valley-specific absorption emission. Through the coupling metasurface electric magnetic Mie modes, intensity lifetime emission neutral excitons, trions, defect bound excitons enhanced shortened, respectively, while spectral shape...
Transition metal dichalcogenides (TMDCs) possess valley pseudospin, allowing photon spin to be coupled electron and enabling initialization readout of both classical quantum information. Rapid valley-dephasing processes have impeded the development scalable, high-performance valleytronic devices operating at room temperature. Here we demonstrate that a chiral resonant metasurface can enable room-temperature valley-selective emission, even with linearly polarized excitation. This platform...
We show through simulation that the improved quantitative rescattering model (QRS) can successfully predict nonsequential double ionization (NSDI) process by intense elliptically polarized laser pulses. Using QRS model, we calculate correlated two-electron and ion momentum distributions of NSDI in Ne exposed to pulses with a wavelength 788 nm at peak intensity $5.0\ifmmode\times\else\texttimes\fi{}{10}^{14}$ W/${\mathrm{cm}}^{2}$. analyze asymmetry doubly charged spectra observed Kang et al....
Using the quantitative rescattering model, we simulate correlated two-electron momentum distributions for nonsequential double ionization of helium by 800 nm laser pulses at intensities in range (2 − 15) × 10 14 W/cm 2 . The experimentally observed V-shaped structure high [ Phys. Rev. Lett. 99 , 263003 ( 2007 ) 10.1103/PhysRevLett.99.263003 ] is attributed to strong forward scattering laser-induced recollision excitation and asymmetric distribution electrons that are tunneling-ionized from...
Using an improved quantitative rescattering model, we calculate the correlated two-electron momentum distributions (CMDs) for nonsequential double ionization of Ar exposed to intense laser pulses with a wavelength 790 nm at peak intensity $1.0\ifmmode\times\else\texttimes\fi{}{10}^{14}\phantom{\rule{4pt}{0ex}}\mathrm{W}/{\mathrm{cm}}^{2}$. We analyze drastic variations in CMDs that were observed by K\"ubel et al. [New J. Phys. 16, 033008 (2014)] transition from near-single-cycle multicycle...
Strong-field ionization can induce electron motion in both the continuum and valence shell of parent ion. Here we report on a joint theoretical experimental investigation laser-induced diffraction xenon. We explore interplay recollision with spin-orbit dynamics xenon cation. On theory side, electron-hole potentials for two different states are constructed, quantitative rescattering model is used to calculate photoelectron momentum distributions (PMDs) high-order above-threshold Measurements...
High-harmonic generation (HHG) is a coherent optical process in which the incident photon energy up-converted to multiples of its initial energy. In solids, under influence strong laser field, electron-hole (e-h) pairs are generated and subsequently driven high momentum within fraction cycle. These dynamics encode band structure, including non-trivial topological properties source material, through both intraband current interband polarization, into harmonic spectrum. course this process,...
