Query: Unified bulk semiclassical theory for intrinsic thermal transport and
  magnetization currents   We reveal the unexpected role of the material inhomogeneity in unifying the
formulation of intrinsic thermal and thermoelectric transport as well as
magnetization currents. The smooth inhomogeneity leads to the position
dependent local band dispersion and phase-space Berry curvature, enabling a
general and rapid access to transport and magnetization currents displaying the
momentum-space Berry curvature physics. Our theory does not invoke the boundary
current, the thermodynamic approach to magnetization or any mechanical
counterpart of statistical forces. By introducing a fictitious inhomogeneity,
it applies to homogeneous samples as well, promoting the inhomogeneity to be a
basic trick in semiclassical transport theories. Such a trick works regardless
of the driving force of transport, e.g., temperature gradient, in contrast to
the trick of fictitious gravitational field in quantum transport theories. We
thus include more general mechanical driving forces and establish the Mott
relation between the resulting transport thermal and electric currents, whereas
this relation for these two currents was previously only known when an electric
field is the driving force.
