Phys. Rev. B 77, 155127 (2008) [9 pages]Phase diagram for bilayer quantum Hall effect at total filling νT=5Received 14 February 2008; revised 3 April 2008; published 25 April 2008 We evaluate the phase diagram of the bilayer quantum Hall effect at total filling νT=5, which is a bilayer phase coherent state at small separations and two uncoupled 5∕2 states at large separations. Based on a combination of variational and exact calculations, we estimate that the transition between these states occurs at a layer separation of approximately one magnetic length. The composite fermion Fermi sea is not found to be relevant for any parameters. © 2008 The American Physical Society URL:
