Quantum transition in bilayer states
Abstract
I study the possible phase transitions when two layers at filling factor νt=1 are gradually separated. In the bosonic case the system should undergo a pairing transition from a Fermi liquid to an incompressible state. In the Fermionic case, the state evolves from an incompressible (1,1,1) state to a Fermi liquid. I speculate that there is an intermediate phase involving charge two quasiparticles.
