Query: Phase Separation Driven by External Fluctuations   The influence of external fluctuations in phase separation processes is
analysed. These fluctuations arise from random variations of an external
control parameter. A linear stability analysis of the homogeneous state shows
that phase separation dynamics can be induced by external noise. The spatial
structure of the noise is found to have a relevant role in this phenomenon.
Numerical simulations confirm these results. A comparison with order-disorder
noise induced phase transitions is also made.
