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.}, issn = {0256-307X}, doi = {10.1088/0256-307X/32/3/037101}, author = {Zhang, Yin-Han and Jun-Ren Shi} }
