Numerical Data - Exceptional points in dissipative coupling polaron-polaritons

This dataset contains the numerical data underlying all figures in the paper. The data correspond to the dispersion relations and linewidth splitting of polaron-polariton branches in two-dimensional semiconductor systems (Transition Metal Dichalcogenides) with dissipative light-matter coupling, modeled via a non-Hermitian Hamiltonian and Green's function formalism. Each *.dat file corresponds to a single panel of a figure. Files are tab-separated plain text with a descriptive header line, a commented column header (#), and two columns of data. Contents: Figure 1: Bare polariton dispersion as a function of momentum and detuning for varying dissipative coupling strength. Figure 2: Polaron-polariton dispersion as a function of momentum and detuning for varying dissipative coupling strength. Figure 3: Polaron-polariton level attraction and exceptional points signatures. Figure 4: Polaron-polariton level attraction and dispersions at fixed detuning values. Column units: All energies are in units of $2\Omega_\mathrm{Re}$, where $\Omega_\mathrm{Re}$ is the real part of the light-matter coupling. Software: Data generated with Python 3 (NumPy, SciPy).
