Query: Magnus Force on Quantum Hall Skyrmions and Vortices   We have discussed here the Magnus force acting on the vortices and skyrmions
in the quantum Hall systems. We have found that it is generated by the
chirality of the system which is associated with the Berry phase and is same
for both the cases.
