  In this paper we discuss bimeron pseudo spin textures for double layer
quantum hall systems with filling factor $\nu =1$. Bimerons are excitations
corresponding to bound pairs of merons and anti-merons.
  Bimeron solutions have already been studied at great length by other groups
by minimising the microsopic Hamiltonian between microscopic trial
wavefunctions. Here we calculate them by numerically solving coupled nonlinear
partial differential equations arising from extremisation of the effective
action for pseudospin textures. We also calculate the different contributions
to the energy of our bimerons, coming from pseudospin stiffness, capacitance
and coulomb interactions between the merons. Apart from augmenting earlier
results, this allows us to check how good an approximation it is to think of
the bimeron as a pair of rigid objects (merons) with logarithmically growing
energy, and with electric charge ${1 \over 2}$. Our differential equation
approach also allows us to study the dependence of the spin texture as a
function of the distance between merons, and the inter layer distance. Lastly,
the technical problem of solving coupled nonlinear partial differential
equations, subject to the special boundary conditions of bimerons is
interesting in its own right.
