Data for Observation of a Dynamic Magneto-chiral Instability in Photoexcited Tellurium

<b>*NOTE*: This dataset has been updated to V3 to include theoretical mode in addition to the experimental data and analysis. Please visit the V3 version: https://doi.org/10.13012/B2IDB-1409842_V3</b>

Dataset and Code Description
This repository provides the data and code used to reproduce key plots from the manuscript and to extend discussions that were only briefly covered therein.
The dataset is organized into five subfolders. Each subfolder corresponds to a unique combination of experimental conditions, including:
• Magnetic field orientation (B ∥ c or B ⟂ c)
• Scan parameter (magnetic field or temperature)
• Pump laser polarization (linear s, linear p, or circular)
• Detection polarization (linear s)
Each folder contains:
• The raw time-domain data files (.mat)
• Oscillator parameters extracted via linear prediction algorithm (.mat)
• MATLAB scripts (.m) that generate plots of the raw data, processed fits, and amplified modes
Folder summary:
1. B_parallel_c_linear_spump_sprobe_field: B ∥ c, s-polarized pump, s-polarized THz detection, magnetic field dependence
2. B_parallel_c_linear_spump_sprobe_temperature: B ∥ c, s-polarized pump, s-polarized THz detection, temperature dependence
3. B_perp_c_linear_spump_sprobe_field: B ⟂ c, s-polarized pump, s-polarized THz detection, magnetic field dependence
4. B_perp_c_linear_spump_sprobe_temperature: B ⟂ c, s-polarized pump, s-polarized THz detection, temperature dependence
5. B_parallel_c_LCPRCP_pump_sprobe_field: B ∥ c, circularly polarized pump (LCP &amp; RCP), s-polarized THz detection, magnetic field dependence

Software requirements:
All scripts were developed and tested in MATLAB R2024a. Each script should be run within its corresponding folder to ensure proper loading of the associated data files.
