  We illustrate with both a Boltzmann diffusion equation and full simulations
of jet propagation in heavy-ion collisions within the Linear Boltzmann
Transport (LBT) model that the spatial gradient of the jet transport
coefficient perpendicular to the propagation direction can lead to a drift and
asymmetry in the transverse momentum distribution. Such an asymmetry depends on
both the spatial position along the transverse gradience and the propagating
length. It can be used to localize the initial jet production positions for
more detailed studies of jet quenching and properties of the quark-gluon plasma
in heavy-ion collisions.
