Phys. Rev. Lett. 83, 1363–1366 (1999)Two New Topologically Ordered Glass Phases of Smectics Confined in Anisotropic Random MediaReceived 18 March 1999; published in the issue dated 16 August 1999 Smectics in strained aerogel exhibit two new glassy phases. The strain both ensures the stability of these phases and determines their nature. One type of strain induces an “ XY Bragg glass,” while the other creates a novel, triaxially anisotropic “ m = 1 Bragg glass.” The latter exhibits anomalous elasticity, characterized by exponents that we calculate to high precision. We predict the phase diagram, and numerous other experimentally observable scaling laws, for the system. © 1999 The American Physical Society URL:
