%0 Journal Article %J Chinese Phys. Lett. %D 2015 %T Density Functional Theory of Composite Fermions %A Zhang, Yin-Han %A Jun-Ren Shi %X We construct a density functional theory for two-dimensional electron (hole) gases subjected to both strong magnetic fields and external potentials. In particular, we are focused on regimes near even-denominator filling factors, in which the systems form composite fermion liquids. Our theory provides a systematic and rigorous approach to determine the properties of ground states in a fractional quantum Hall regime that is modified by artificial structures. We also propose a practical way to construct an approximated functional. %B Chinese Phys. Lett. %V 32 %P 037101 %8 mar %G eng %] 000350955600025 %R 10.1088/0256-307X/32/3/037101
