Such small values of the dimensionless coupling coefficient ([[xi].sup.2.sub.NI] [approximately equal to] [10.sup.-6]) would place a large weight on the terms from the bulk ordering potential, strongly encouraging uniaxial order at the bulk-minimizing value of the scalar
order parameter.
It is further possible and common to define scalar
order parameters, which are connected to the second-order alignment tensor.
In Sections 2.1 and 2.2, we define the
order parameters and symmetry generators of the microscopic theory underlying HTSC and explain how the SO(5) symmetry arises from these structures.
The
order parameter [PSI] is very small in this range, and higher order terms of [PSI] can be neglected.
The most active factor--human resources--is involved in this
order parameter. This
order parameter is mainly influenced by two factors including organizational experience and knowledge capital.
Minimization of free energy (1.2) with respect to the
order parameter [PSI]([??]), and the potential vector [??], conduces to the fundamental equations of Ginzburg-Landau theory,
In photo-excitable NLC, another effective mechanism for
order parameter change is Trans-Cis isomerism of azo-NLC or azo-molecule doped-NLC [71,73,76].
In this case, three time instants, t = 1.0, t = 1.5, and t = 2.0, are considered, while the heat source velocity and the fractional
order parameter remain constant as v = 2.0 and [alpha] = 0.25, respectively.
Haken has proved that when [[lambda].sub.k] = c (c > 0), the largest initial
order parameter will win and the network will then converge.
The parameters measured were the hyperfine splitting constants (2[T.sup.[parallel]] and 2[T.sup.[perpendicular to]]), allowing for calculation of the
order parameter [23]:
The term [X.sub.i] is the current value of the
order parameter, while [[alpha].sub.i] and [[beta].sub.i] are the maximum and minimum values of that
order parameter, respectively.
One may try to estimate a spatially averaged
order parameter and the corresponding effective critical temperature for a bundle consisting of a mixture of these two types of SWCNTs.
