Nematic colloids: fine structure of  boojums and effective pair interactions between spherical colloidal particles with tangential

*** Abstract: [#u1ca5214]
I will present results of theoretical calculations for nematic
configurations around a single and a pair of spherical
colloidal particles. Inducing tangential anchoring on the nematic
director. Effects of temperature, particle size,
and anchoring strength on the structure of the core of a boojum will be discussed. For two particles nematic distortions induce effective interactions. The interactions are analyzed as a function of the anchoring strength.
Finally, I will make a connection with experiments of Lavrentovich on
similar system.
