Renormalization-group theory for the phase-field crystal equation.
We derive a set of rotationally covariant amplitude equations for use in multiscale simulation of the two-dimensional phase-field crystal model by a variety of renormalization-group (RG) methods. We show that the presence of a conservation law introduces an ambiguity in operator ordering in the RG procedure, which we show how to resolve. We compare our analysis with standard multiple-scale tech...
متن کاملLiquid Crystal and Optics Group
Several authors [1-5] have studied the effect of a constant shear rate (steady state condition) on the planar structure of a cholesteric liquid crystal (CLC). In these cases the shearing is obtained by constant rotation of a rheogoniometer. The main conclusions are: 1) the CLC layers can slip freely, and a uniform helical axis tilt is produced at low shear rate. 2) a broken structure is induced...
متن کاملGroup Theory
Symmetry has sung its siren song to Physicists since the beginning of time, or at least since before there were Physicists. Today the ideas of symmetry are incorporated into a subject with the less imaginative and suggestive name of Group Theory. This Chapter introduces many of the ideas of group theory that are important in the natural sciences. Natural philosophers in the past have come up wi...
متن کاملGroup Theory
The first version of these notes was written for a first-year graduate algebra course. As in most such courses, the notes concentrated on abstract groups and, in particular, on finite groups. However, it is not as abstract groups that most mathematicians encounter groups, but rather as algebraic groups, topological groups, or Lie groups, and it is not just the groups themselves that are of inte...
متن کاملGroup Theory
The notion of modular arithmetic is related to that of the remainder in Euclidean division. The operation of finding the remainder is sometimes referred to as the modulo operation, and denoted with ”mod” used as an infix operator. For example, the remainder of the division of 16 by 12 is denoted by 16 mod 12; as this remainder is 4, we have 16 mod 12 = 4. The congruence, indicated by ”≡” follow...
