Query: Meron Pseudospin Solutions in Quantum Hall Systems   In this paper we report calculations of some pseudospin textures for bilayer
quantum hall systems with filling factor $ \nu =1$. The textures we study are
isolated single meron solutions. Meron solutions have already been studied at
great length by others by minimising the microscopic Hamiltonian between
microscopic trial wavefunctions. Our approach is somewhat different. We
calculate them by numerically solving the nonlinear integro -differential
equations arising from extremisation of the effective action for pseudospin
textures. Our results can be viewed as augmenting earlier results and providing
a basis for comparison.Our differential equation approach also allows us to
dilineate the impact of different physical effects like the pseudospin
stiffness and the capacitance energy on the meron solution.
