Ferroelectricity in Incommensurate Magnets
A. B. Harris, G. Lawes
We review the phenomenology of coupled magnetic and electric order parameters for systems in which ferroelectric and incommensurate magnetic order occur simultaneously. We discuss…
Magnetically driven ferroelectric order in NiVO
G. Lawes, A. B. Harris, T. Kimura +8
We show that for NiVO long-range ferroelectric and incommensurate magnetic order appear simultaneously in a single phase transition. The temperature and magnetic field…
Dimer Statistics on a Bethe Lattice
A. B. Harris, Michael Cohen
We discuss the exact solutions of various models of the statistics of dimer coverings of a Bethe lattice. We reproduce the well-known exact results for noninteracting hard-core dim…
Quantum Theory of Chiral Interactions in Cholesteric Liquid Crystals
A. S. Issaenko, A. B. Harris, T. C. Lubensky
We study the effective chiral interaction between molecules arising from quantum dispersion interactions within a model in which a) the dominant excited states of a molecule form a…
Chirality in Liquid Crystals: from Microscopic Origins to Macroscopic Structure
T. C. Lubensky, A. B. Harris, Randall D. Kamien +1
Molecular chirality leads to a wonderful variety of equilibrium structures, from the simple cholesteric phase to the twist-grain-boundary phases, and it is responsible for interest…
Quantum Fluctuations in the Annni Model
A. B. Harris, C. Micheletti, J. M. Yeomans
We obtain the ANNNI model from a Heisenberg model with large single--ion anisotropy energy, , as might be relevant for helical spin systems. We treat quantum fluctuations to low…
