abstract = {We theoretically and experimentally study nematic liquid
crystal equilibria within shallow rectangular wells. We
model the wells within a two-dimensional Oseen–Frank
framework, with strong tangent anchoring, and obtain
explicit analytical expressions for the director fields and
energies of the ‘diagonal’ and ‘rotated’ solutions
reported in the literature. These expressions separate the
leading-order defect energies from the bulk distortion
energy for both families of solutions. The continuum
Oseen–Frank study is complemented by a microscopic
mean-field approach. We numerically minimize the mean-field
functional, including the effects of weak anchoring,
variable order and random initial conditions. In particular,
these simulations suggest the existence of higher-energy
metastable states with internal defects. We compare our
theoretical results to experimental director profiles,
obtained using two types of filamentous virus particles,
wild-type fd-virus and a modified stiffer variant (Y21M),
which display nematic ordering in rectangular chambers, as
found by confocal scanning laser microscopy. We combine our
analytical energy expressions with experimentally recorded
frequencies of the different equilibrium states to obtain
explicit estimates for the extrapolation length, defined to
be the ratio of the nematic elastic constant to the
anchoring coefficient, of the fd-virus.},
