      abstract     = {When liquid crystals are confined to finite volumes, the
                      competition between the surface anchoring imposed by the
                      boundaries and the intrinsic orientational symmetry-breaking
                      of these materials gives rise to a host of intriguing
                      phenomena involving topological defect structures. For
                      synthetic molecular mesogens, like the ones used in
                      liquid-crystal displays, these defect structures are
                      independent of the size of the molecules and well described
                      by continuum theories. In contrast, colloidal systems such
                      as carbon nanotubes and biopolymers have micron-sized
                      lengths, so continuum descriptions are expected to break
                      down under strong confinement conditions. Here, we show, by
                      a combination of computer simulations and experiments with
                      virus particles in tailor-made disk- and annulus-shaped
                      microchambers, that strong confinement of colloidal liquid
                      crystals leads to novel defect-stabilized symmetrical domain
                      structures. These finite-size effects point to a potential
                      for designing optically active microstructures, exploiting
                      the as yet unexplored regime of highly confined liquid
                      crystals.},
