2D gel of P4 knots: Two dimensional gel of low complexity knots
extracted from P4.Notice the absence of the 4-crossing knot and
the prevalence of toroidal knots over twist knots.

Spooling (In collaboration with Steve Harvey)

Random Spooling:The Random spooling model was
introduced in Arsuaga and Diao 2008. The goal was
to introduce a spooling like conformation that produces
knots. (Figure generated by R.. Scharein)

A realization of the 8.1 knot in the 1-slab
Motivated by the results on P4 cosmids we asked
what is the shortest piece of rope needed to make a knot in
a tightly confined region (ie. 1-slab)(Submitted for publication)

A second realization of the 8.1 knot in the 1-slab:
These two realizations are not equivalent when
confined to the the 1-slab
