The single-species asymmetric diffusion model can also be interpreted as a model of surface growth above a horizontal substrate. The interfacial width of the surface obeys a well-known scaling law with a critical exponent of 3/2. This exponent was confirmed analytically by Gwa and Spohn through a Bethe ansatz calculation.
