# 2D Quantum Turbulence in Polariton Condensates

## TL;DR

This paper investigates 2D quantum turbulence in polariton condensates, demonstrating the potential to observe energy cascades and scaling laws like the -5/3 power law over large scales.

## Contribution

It shows that polariton condensates are suitable for observing 2D quantum turbulence and confirms the presence of energy spectra following the -5/3 power law.

## Key findings

- Energy spectra of clustered vortices exhibit -5/3 power law
- Cascade observed over almost 2 decades in optimal conditions
- Shape of energy spectra depends on excitation procedure

## Abstract

The coexistence of the energy and enstrophy cascades in 2D quantum turbulence is one of the important open questions in the studies of quantum fluids. Here, we show that polariton condensates are particularly suitable for the possible observation of scaling on sufficiently large scales. The shape of raw energy spectra depends on the procedure of condensate excitation (stirring), but the energy spectra of clustered vortices always exhibit the -5/3 power law. In the optimal case, the cascade can be observed over almost 2 decades.
