Data for "Detecting a Long-Lived False Vacuum with Quantum Quenches"

This dataset contains the numerical data and scripts used to generate the figures in the article: Detecting a Long-Lived False Vacuum with Quantum Quenches, Phys. Rev. Lett. 133, 240402 (2024). The files in the folder "figure2" are the two datasets used to produce the Figure 2 in the paper. The files have 4 rows, the first contains the timesteps, the second the Von Neuman entropy, the third the magnetization (used for the figure in the paper), and the fourth the truncation error (used for the discussion in the supplemental material). The files in the folder "figure3" are the datasets used to produce the Figure 3. The files have to rows, the first contains eigenvalues/frequencies, the second the values of the magnetization Sz. The file names are following the notation introduced in the paper.
