Abstract
We introduce a simple model of yeastlike growth of fungi colonies, which exhibits a continuous roughening transition far from equilibrium from a smooth ( ) to a rough phase ( ) in dimensions. At the transition some scaling exponents are calculated by mapping the problem onto a directed percolation process. The model reproduces the roughening transition observed in some experiments of fungal growth.
