Data sets of article "Emergence of Turbulence in a counterflow geometry of 2D Polariton Quantum Fluids"

DOI

The data deposited in this repository were generated as part of a research project investigating turbulence in quantum fluids of polaritons and are associated with the corresponding scientific publication. They originate from two-dimensional numerical simulations describing the dynamics of a polariton fluid in a semiconductor microcavity.

The simulations rely on the numerical solution of a set of coupled Gross–Pitaevskii–type equations describing the excitonic and photonic fields. This model captures the out-of-equilibrium dynamics of polaritons in the coherent regime, including dispersion, excitonic interactions, losses, and coherent optical pumping. In this study, the polariton fluid is driven by two counter-propagating coherent lasers, enabling the exploration of different dynamical regimes of the system. The simulation code used to generate these data is available in open access on GitHub. The archived data primarily consist of two-dimensional complex fields corresponding to the photon and exciton wavefunctions. From these complex fields, the spatial distributions of density and phase for both components of the system can be obtained. From the simulated fields, several physical observables are computed, including the different contributions to the system energy (kinetic energy, interaction energy, etc.), following the expressions defined in the associated publication. In addition, spatial and temporal averaging of the fields allows the calculation of the first-order autocorrelation function 𝑔(1), which acts as an order parameter and enables the characterization of the different dynamical regimes of the system.

The name of each file corresponds to the specific figure in the main article, where the specific theoretical and numerical information is given. The files are in H5 format with explicit naming, allowing a simple reconstruction of the figure. The article will be freely accessible on ArXiv.
