Near-field heat transfer and drag resistance in bilayers of composite fermions
Physical Review B(2024)
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.
