Question
Papers by Meyer and by Cladis and Kléman established that these topological defects could be stabilized against an “escape to the third dimension” in cylindrical samples of liquid crystals. For 10 points each:
[10m] Name these orientational topological defects that, in the hexatic phase, correspond to sites with a coordination number of 5 or 7.
ANSWER: disclinations
[10e] These other topological defects are equivalent to a bound pair of disclinations. The breakdown of translational order caused by these defects can be parametrized by their Burgers vector.
ANSWER: dislocations
[10h] The effect of both disclinations and dislocations on a crystal can be examined using a construction named for this mathematician, in which a namesake “cut” is made and repaired.
ANSWER: Vito Volterra [accept Volterra construction]
