Query: Abelian origin of $\nu=2/3$ and $2+2/3$ fractional quantum Hall effect   We investigate the ground state properties of fractional quantum Hall effect
at the filling factor $\nu=2/3$ and $2+2/3$, with a special focus on their
typical edge physics. Via topological characterization scheme in the framework
of density matrix renormalization group, the nature of $\nu=2/3$ and $2+2/3$
state are identified as Abelian hole-type Laughlin state, as evidenced by the
fingerprint of entanglement spectra, central charge and topological spins.
Crucially, by constructing interface between $2/3$ ($2+2/3$) state and
different integer quantum Hall states, we study the structures of the
interfaces from many aspects, including charge density and dipole moment. In
particular, we demonstrate the edge reconstruction by visualizing edge channels
comprised of two groups: the outermost $1/3$ channel and inner composite
channel made of a charged mode and neutral modes.
