    • One simply balances an elastic distortion energy against a surface anchoring energy [13]. See also Sec. III. By a similar argument one find that for droplets with a preference for homeotropic anchoring attain a homogeneous director field if sufficiently small. J. H. Erdmann, S. Zumer. and J. W. Doane, Phys. Rev. Lett. 64, 1907 (1990).

    • We also investigated bipolar parabolas of revolution and found the free-energy diffrence between these and circle sections of revolutionto be under 1% for all droplet volumes. For this reason, we do not discuss parabolas of revolution and take the circle section of revolution as representative for the class of elongated, pointed droplets.

    • After submission of the manuscript our attention was drawn on a paper by A. V. Kaznacheev, M. M. Bogdanov, and S. A. Taraskin, JETP 95, 57 (2002). Their study focuses on the shape of bipolar nematic droplets larger than ≈20 μm, away from the crossover region.

    • We only explicitly consider spherical and elongated shapes, not toroidal or flat ones as these are (within our assumptions) structures of higher energy, where we note that oblate spheroid and lens-shaped droplets can become stable if - 1<ω<0 [8,15,30,37].

    • The accuracy of our theory should deteriorate when the droplets become of the order of the size of the nematogens, which is about 1 μm for fd virus. A continuum description then loses its validity.
