  We substantiate a complete picture of the "bulk-edge correspondence"
conjecture for topological phases. By studying the eigenstates in the
entanglement spectrum for both the ideal and realistic Coulomb ground state of
the fractional quantum Hall system, it is verified that the eigenstates in the
universal part of the entanglement spectrum purely lie in the Hilbert space of
the edge excitations projected onto the physical Hilbert space of the subsystem
itself. Hence, not only are the eigenlevels in the entanglement spectrum in
one-to-one correspondence with the eigenenergies of an effective dynamical edge
Hamiltonian, but all the eigenstates are confirmed to be the actual (projected)
edge excitations of the subsystem. This result also reveals the possibility of
extracting the full information of the edge excitations from the state of the
subsystem reduced from a geometric cut of the pure ground state of the total
system in topological phases.
