Query: Anisotropic magnetoresistance and piezoelectric effect in GaAs Hall
  samples   In this work, we argue that an anisotropic interaction potential may
stabilize anisotropic liquid phases of electrons even in a strong magnetic
field regime where normally one expects to see only isotropic quantum Hall or
isotropic Fermi liquid states. We use this approach to support a theoretical
framework that envisions the possibility of an anisotropic liquid crystalline
state of electrons in the lowest Landau level. In particular, we argue that an
anisotropic liquid state of electrons may stabilize in the lowest Landau level
close to the liquid-solid transition region at filling factor $\nu=1/6$ for a
given anisotropic Coulomb interaction potential. Quantum Monte Carlo
simulations for a liquid crystalline state with broken rotational symmetry
indicate stability of liquid crystalline order consistent with the existence of
an anisotropic liquid state of electrons stabilized by anisotropy at filling
factor $\nu=1/6$ of the lowest Landau level.
