Quandles and racks are algebraic structures referred to in knot theory. Are there links to thorough introductions for researchers in how they are used in physics research?

In statistical mecanics the Yang-Baxter Equation leads to a wealth of knot invariants and indeed they show up there: http://arxiv.org/pdf/math/0409202.pdf
If there is one candidate to what, I surmize, you are looking for it must be in that direction.
Each birack (hence a rack) provides a solution of the set-theoretic Yang-Baxter equation. Furthermore, one can define the homology theory for set-theoretic Yang-Baxter equation, which is a generalized version of the rack homology.
