abstract:In biochemistry, the binding of a ligand to a macromolecule is often enhanced if there are already other ligands present on the same macromolecule (this is known as Cooperative binding). The Hill coefficient provides a way to quantify this effect.
In a high-intensity optics field, using rotating waves approximation (RWA) and the special transform, the problem oftwo-level atoms transition attributes to the Hillequation.
