Interface Roughening in Nonequilibrium Phase-Separated Systems

Author(s): M. Besse, G. Fausti, M. E. Cates, B. Delamotte, and C. Nardini

Interfaces of phase-separated systems roughen in time due to capillary waves. Because of fluxes in the bulk, their dynamics is nonlocal in real space and is not described by the Edwards-Wilkinson or Kardar-Parisi-Zhang (KPZ) equations, nor their conserved counterparts. We show that, in the absence o…
