A continuum approximation for the excitations of the interface in the quantum Heisenberg model.
A Discrete Model For Pattern Formation In Volatile Thin Films
We introduce a model, similar to diffusion limited aggregation (DLA), which serves as a discrete analog of the continuous dynamics of evaporation of thin liquid films. Within mean field approximation the dynamics of this model, averaged over many realizations of the growing cluster, reduces to that of the idealized evaporation model in which surface tension is neglected. However fluctuations beyond the mean field level play an important role, and...
