Shout-out to my former visiting student Yiheng Zhang, and his new paper in PRE, in which I had a minor part. A fantastic story about nematics, topology, and effective field theory.
Let me offer you some CLIFF NOTES!

Nematic liquid crystals are soft matter systems in which elongated molecules align and form long-range oriented fields, in 2 or 3 dimensions. They have a long history, many practical applications, and are increasingly recognized for the many roles they play in biology.

The local “director field” of liquid crystals tends to be nice and smooth, but it is possible that a little “defect” sneaks in. For instance, these pictures show a +1/2 and a -1/2 defect, where locally the smooth field is disturbed.
