Knot energy

Knot energy refers to the energy associated with the configuration or shape of a knot in a physical system, usually relating to the fields of physics, mathematics, or materials science. It primarily considers the work done against forces (such as tension) to create or maintain a knot. In a more specific context, knot energy can be applied to biological systems, like DNA, where the energy configuration of a knotted or constrained DNA molecule can affect its biological functions and stability.
