Flexoelectricity , incommensurate phases and the Lifshitz
The solutions for the minimizers of the energy density f (q, p) = Aq2 + Bq4 + p2 + gA,B + ( ) β κ − + | | + | | ′ ′ ′ ′ q p p q q p 2 2 describe the flexoelectric effect with a flexoelectric coupling coefficient β. The order parameters q and p can be visualized as strain and polarisation, respectively. The parameter κ denotes the ratio of intrinsic length scales for q and p. We show that the st...
متن کاملLifshitz point in the smectic A phases
2014 The triple point where three smectic phases are present (the Sm A1, the Sm A2 and the Sm à phases) is a Lifshitz point associated with a polarization wave parallel to the layers. We show that interesting dielectric properties may be observed in the vicinity of this Lifshitz point. J. Physique 44 (1983) 273-278 FEVRIER 1983, Classification Physics Abstracts 61.30G 64.60K 77.80B
متن کاملCommensurate phases , incommensurate phases and the devil ’ s staircase
Modulated structures with periods which are incommensurable (or high-order commensurable) with the basic lattice are quite common in condensed-matter physics. The structure may be another lattice, a periodic lattice distortion, a helical or sinusoidal magnetic structure, or a charge density wave in one, two or three dimensions. This review surveys recent theories on the transition between comme...
متن کاملAmorphous structures and incommensurate phases
2014 A comparison is made between incommensurate phases related with the well known Frendel-Kontorova problem, and amorphous structures, on the basis of a problem of conflict between different symmetries. This similarity leads to a fruitful comparison of solutions with the introduction of a 3-dimensional devil’s staircase for the characterization of amorphous structures. Finally for amorphous s...
متن کاملQuantum Lifshitz Point
I study a quantum Lifshitz point in a three-dimensional itinerant antiferromagnet, in particular the scaling of the Néel temperature, the correlation length, the staggered susceptibility, the specific heat coefficient and the resistivity. At low temperatures, the model is shown to have the inverse staggered susceptibility and the resistivity varying as T5/4, and the specific heat coefficient va...
