Query: Hall Viscosity of the Composite-Fermion Fermi Seas for Fermions and
  Bosons   The Hall viscosity has been proposed as a topological property of
incompressible fractional quantum Hall states and can be evaluated as Berry
curvature. This paper reports on the Hall viscosities of composite-fermion
Fermi seas at $\nu=1/m$, where $m$ is even for fermions and odd for bosons. A
well-defined value for the Hall viscosity is not obtained by viewing the $1/m$
composite-fermion Fermi seas as the $n\rightarrow \infty$ limit of the Jain
$\nu=n/(nm\pm 1)$ states, whose Hall viscosities $(\pm n+m)\hbar \rho/4$
($\rho$ is the two-dimensional density) approach $\pm \infty$ in the limit
$n\rightarrow \infty$. A direct calculation shows that the Hall viscosities of
the composite-fermion Fermi sea states are finite, and also relatively stable
with system size variation, although they are not topologically quantized in
the entire $\tau$ space. I find that the $\nu=1/2$ composite-fermion Fermi sea
wave function for a square torus yields a Hall viscosity that is expected from
particle-hole symmetry and is also consistent with the orbital spin of $1/2$
for Dirac composite fermions. I compare my numerical results with some
theoretical conjectures.
