Spinodal decomposition to a lamellar phase: effects of hydrodynamic flow
G. Gonnella, E. Orlandini, J. M. Yeomans
Results are presented for the kinetics of domain growth of a two-dimensional fluid quenched from a disordered to a lamellar phase. At early times when a Lifshitz-Slyozov mechanism…
A complete devil's staircase in the Falicov-Kimball model
C. Micheletti, A. B. Harris, J. M. Yeomans
We consider the neutral, one-dimensional Falicov-Kimball model at zero temperature in the limit of a large electron--ion attractive potential, U. By calculating the general n-ion i…
Surface spin-flop phases and bulk discommensurations in antiferromagnets
C. Micheletti, R. B. Griffiths, J. M. Yeomans
Phase diagrams as a function of anisotropy D and magnetic field H are obtained for discommensurations and surface states for a model antiferromagnet in which is parallel to the…
Complete wetting in the three-dimensional transverse Ising model
A. B. Harris, C. Micheletti, J. M. Yeomans
We consider a three-dimensional Ising model in a transverse magnetic field, and a bulk field . An interface is introduced by an appropriate choice of boundary conditions. At…
Lifting of Multiphase Degeneracy by Quantum Fluctuations
A. B. Harris, C. Micheletti, J. M. Yeomans
We study the effect of quantum fluctuations on the multiphase point of the Heisenberg model with first- and second-neighbor competing interactions and strong uniaxial spin anisotro…
An Upsilon Point in a Spin Model
C. Micheletti, F. Seno, J. M. Yeomans
We present analytic evidence for the occurrence of an upsilon point, an infinite checkerboard structure of modulated phases, in the ground state of a spin model. The structure of t…
