## Summary

The study "Near-field heat transfer and drag resistance in bilayers of composite fermions" by Dmitry Zverevich and Alex Levchenko investigates heat transfer within electron double layers of correlated composite fermion quantum liquids. The research focuses on the near-field regime, where interlayer energy transfer is primarily governed by the Coulomb interaction of thermally-driven charge density fluctuations. By analyzing various limiting cases of the composite fermion Chern-Simons gauge theory, including ballistic, diffusive, and hydrodynamic regimes, the corresponding interlayer thermal conductance is computed. The study also delves into the phenomenon of plasmon enhancement of heat transfer within these systems, shedding light on how plasmons play a role in enhancing efficiency. Additionally, the relationship between heat transfer conductance and drag resistance is explored for electron states formed in the fractional quantum Hall effect at even denominator filling fractions. This analysis provides valuable insights into how drag resistance affects heat transfer properties in these unique systems, contributing to our understanding of thermal transport phenomena in correlated quantum liquid systems.
