摘要：In PNAS, the liquid crystal group of the Soft Materials Research Center at the University of Colorado Boulder, led by N. A. Clark, reports on the discovery of a ferroelectric nematic fluid NF, an additional state of matter (Chen et al., ref. 1) (Fig. 1 A ). Such a phase has been expected at least since 1916 (2), but first-principle experiments have never demonstrated its existence until now. To many, the word “nematic” is associated with the informational revolution of the 20th century and portable displays enabled by this liquid crystal. That nematic (N), shown in Fig. 1 B and C , is a nonpolar version of the discovered nematic.
