Abstract
We report the first observation of a cholesteric phase which appears as an island surrounded by smectic- phases in a temperature-concentration phase diagram. The island of cholesteric form results from large fluctuations of two, collinear, incommensurate density waves whose coexistence violates smectic- ordering. It provides novel evidence that smectic- fluidity cannot support two incommensurate lengths.
