dc.description.abstract
We introduce an exactly solvable fermion chain that describes a ν=1/3
fractional quantum Hall (FQH) state beyond the thin-torus limit. The ground
state of our model is shown to be unique for each center-of-mass sector, and
it has a matrix product representation that enables us to exactly calculate
order parameters, correlation functions, and entanglement spectra. The ground
state of our model shows striking similarities with the BCS wave functions and
quantum spin-1 chains. Using the variational method with matrix product
ansatz, we analytically calculate excitation gaps and vanishing of the
compressibility expected in the FQH state. We also show that the above results
can be related to a ν=1/2 bosonic FQH state.
