Show affiliationsWe investigate the effect of fluctuations in the effective Hamiltonian that describes the microphase separation in random copolymers. This Hamiltonian is previously studied on the level of mean-field theory where a phase transition to a phase with periodic microdomain structure was predicted. It is shown that the one-loop treatment of fluctuations is exact in the thermodynamic limit and that the phase predicted by the mean field is unstable within the framework of the studied Hamiltonian.
