摘要：
We calculate the topological entanglement entropy in bilayer quantum Hall systems, dividing the set of quantum numbers into four parts. This topological entanglement entropy allows us to draw a phase diagram in the parameter space of layer separation and tunneling amplitude. We perform a finite-size scaling analysis of the topological entanglement entropy in order to see the quantum phase transition clearly.
