Morse Theory and Meron-Mediated Interactions Between Disclination Lines in Nematic Materials

The topological understanding of nematic liquid crystals has traditionally centered on defects and their classification via homotopy invariants. Here, we draw upon several aspects of Morse theory to describe a finer approach to topology that characterizes the isotopy invariants within a given homoto...
