  We describe theoretically a setup in which a tapered optical nanofibre is
introduced into an optical lattice potential for cold atoms. Firstly, we
consider the disturbance to the geometry of the lattice potential due to
scattering of the lattice lasers from the dielectric fibre surface and show
that the resulting distortion to the lattice can be minimized by placing the
fibre at an appropriate position in the lattice. We then calculate the
modifications of the local potentials that are achievable by transmitting
off-resonant light through the fibre. The availability of such a technique
holds the potential to deterministically create and address small well-defined
samples of atoms in the evanescent field of the tapered nanofibre.
