2026-05-06 Dataset for "Correlation between Excited-States and Low-Energy ATI Spectrum in Hydrogen Atoms under Two-Color Laser Fields" doi:10.57760/sciencedb.35349 en Dataset Description: 1. Overview​This dataset contains the raw data and plotting scripts necessary to regenerate all figures (Figures 1-4) presented in the accompanying paper, "Correlation of Channel-Closing Effects and Terahertz Radiation". The primary purpose of this dataset is to ensure the full reproducibility of the graphical results. The figures were created using two different plotting tools: XMGrace​ and Gnuplot, as detailed below. ​2. Dataset Structure​The main directory Figures_Data/ is organized into four subdirectories, each corresponding to a specific figure in the paper:Figures_Data/├── figure1/├──figure2/├── figure3/├── figure4/3. Content of Each Subdirectory （1) figure 1Content description: [Total excitation probability and photocurrent oscillation as a function of laser intensity.]Plotting tool: XMGraceData files:rydion1.dat: Excitation probability for single-color 800 nm laser pulse.rydion2p0.dat: Excitation probability for two-color 800 +400nm laser pulse with phase = 0.rydion2p1.dat: Excitation probability for two-color 800 +400nm laser pulse with phase = π.curone.dat: Photocurrent for single-color 800 nm laser pulse.curp0.dat: Photocurrent for two-color 800 +400nm laser pulse with phase = 0.curp1.dat: Photocurrent for two-color 800 +400nm laser pulse with phase = π.curp08.dat: Photocurrent for two-color 800 +400nm laser pulse with phase = 0.8 π.thzp0.dat: THz for two-color 800 +400nm laser pulse with phase = 0.thzp10.dat: THz for two-color 800 +400nm laser pulse with phase = π.Plotting script: fig1 (XMGrace project file)Notes: The data were obtained fromnumerical simulations based on the method described in Section 2. Columns in data files: Column 1 = laser intensity (W/cm²), Column 2 = photocurrent or THz intensity or excitation probability(arb. units).（2）figure 2Content description: [Electron momentum distributions for different laser intensity.]Plotting tool: GnuplotData files:spec125.dat: Electron momentum distributions for laser intensity $1.25*10^{14} W/cm^2$spec135.dat: Electron momentum distributions for laser intensity $1.35*10^{14} W/cm^2$spec18.dat: Electron momentum distributions for laser intensity $1.8*10^{14} W/cm^2$spec20.dat: Electron momentum distributions for laser intensity $2.0*10^{14} W/cm^2$Plotting script:plot2(Gnuplot script)To generate fig2.eps, follow these steps:Navigate to the corresponding subdirectory (e.g., cd figure2).Launch Gnuplot from your terminal/command line.Within the Gnuplot environment, load the script:gnuplot> load 'plot2'This command will execute the script and generate fig2.eps in the same directory.（3）figure 3Content description: [Laser fields with the fundamental and second harmonic.]Plotting tool: XMGraceData files:laserp0.dat: Laser fields  for two-color 800 +400nm laser pulse with phase = 0.laserp1.dat: Laser fields  for two-color 800 +400nm laser pulse with phase = π.Plotting script: fig3 (XMGrace project file)（4）figure 4Content description: [Total excitation probability and photocurrent oscillation as a function of laser wavelength.]Plotting tool: XMGraceData files:rydion1.dat: Excitation probability for single-color laser pulse with fixed laser intensity.rydion2.dat: Excitation probability for single-color laser pulse with fixed photo numbers for ionization.dtn1.dat: Photocurrent for single-color laser pulse with fixed laser intensity.dtn2.dat: Photocurrent for single-color laser pulse with fixed photo numbers for ionization.Plotting script: fig4 (XMGrace project file)4.
