Near-field heat transfer and drag resistance in bilayers of composite fermions

Abstract

Heat transfer is studied in the system of electron double layers of correlated composite fermion quantum liquids. In the near-field regime, the primary mechanism governing interlayer energy transfer is mediated by the Coulomb interaction of thermally-driven charge density fluctuations. The corresponding interlayer thermal conductance is computed across various limiting cases of the composite fermion Chern-Simons gauge theory, encompassing ballistic, diffusive, and hydrodynamic regimes. Plasmon enhancement of the heat transfer is discussed. The relationship between the heat transfer conductance and the drag resistance is presented for electron states formed in the fractional quantum Hall effect of even denominator filling fractions.
