We have submitted our experimental and analysis dataset (CsPbBr3_spinor_dataset_KY_8th_SA.xlsx), which contains all numerical data used to generate the figures in the associated manuscript. Each sheet in the Excel file corresponds to a specific figure or supplementary figure.

No additional compressed archives are included. Some large datasets (Figs. S7–S9) are not included due to file size limitations and can be made available upon reasonable request.

Description

File: CsPbBr3_spinor_dataset_KY_8th_SA.xlsx

This Excel file contains multiple sheets corresponding to experimental measurements and theoretical analysis of spinor polariton condensation in CsPbBr₃ microcavities.

Each sheet is labeled according to the figure number in the manuscript.

General Data Structure

• Colormap data
  • First column: in-plane wavevector (µm⁻¹) or pumping fluence
  • First row: energy (eV) or fluence (J/cm²)
  • Matrix values:
    • Photoluminescence (PL) intensity (a.u.)
    • Stokes parameters (dimensionless)
• Plot data
  • Columns correspond to physical quantities such as:
    • PL intensity (a.u.)
    • Full width at half maximum (FWHM, eV)
    • Energy (eV)
    • Wavelength (nm)
    • Stokes parameters

Figures 1a–1d

Colormap data of unpolarized PL dispersion under different pumping fluences.

• First column: in-plane wavevector (µm⁻¹)
• First row: energy (eV)
• Values: PL intensity (a.u.)

Figures 1e–1g

Fluence-dependent measurements:

• PL intensity (a.u.)
• FWHM (eV)
• Peak energy (eV)

Two simultaneously observed spinor-condensed modes are included.
One of them was observable at the fluence above 9.21 µJ/cm², thus the data sets below 9.21 µJ/cm are missing ("null").

Figures 2a–2f

Colormap data of Stokes parameters:

• S1, S2, S3 (dimensionless)
• Below- and above-threshold regimes

Figures 3b–3e, 3g–3j

Fluence-dependent Stokes parameters for two samples with different detuning energies.

• First column: pumping fluence
• First row: energy (eV)

Figure 4a

Comparison of theoretical and experimental Stokes parameters:

• Theoretical:
  • S, Sx/S, Sy/S, Sz/S
• Experimental:
  • S0, S1, S2, S3

Figure 4b

Blueshift of the condensed polariton mode:

• P: polariton density (µm⁻²)
• exp: experimentally measured peak energy (eV)

Key Information Sources

All data were obtained from:

• Angle-resolved photoluminescence (ARPL) measurements
• Polarization-resolved spectroscopy
• Interferometric coherence measurements
• Numerical simulations based on a spin-dependent Gross–Pitaevskii model

Code/Software

Data analysis and simulations were performed using standard scientific computing tools.

• Python (NumPy, SciPy, Matplotlib)
• MATLAB (modeling and fitting)
• Origin / Igor Pro (data visualization)

Workflow

1. Data acquisition (ARPL, polarization-resolved PL)
2. Extraction of dispersion relations and peak parameters
3. Calculation of Stokes parameters
4. Numerical simulation using spinor Gross–Pitaevskii equations
5. Figure generation

Notes

• No special missing-value codes are used
• All datasets are directly usable without preprocessing
• Large datasets not included can be requested from the authors
