Query: Investigating anisotropic quantum Hall states with bi-metric geometry   We construct a low energy effective theory of anisotropic fractional quantum
Hall (FQH) states. We develop a formalism similar to that used in the bi-metric
approach to massive gravity, and apply it to describe abelian anisotropic FQH
states in the presence of external electromagnetic and geometric backgrounds.
We derive a relationship between the shift, the Hall viscosity, and a new
quantized coupling to anisotropy, which we term "anisospin". We verify this
relationship by numerically computing the Hall viscosity for a variety of
anisotropic quantum Hall states using the density matrix renormalization group
(DMRG). Finally, we apply these techniques to the problem of nematic order and
clarify certain disagreements that exist in the literature about the meaning of
the coefficient of the Berry phase term in the nematic effective action.
