The combined order parameter and relaxation measurements give unique knowledge of the structural fluctuations for membrane lipids and membrane proteins.
22.
To make this quantitative, an orientational order parameter is usually defined based on the average of the second Legendre polynomial:
23.
This means that ARPES cannot determine whether the HTS order parameter has the " d " symmetry or not.
24.
Some phase transitions, such as superconducting and ferromagnetic, can have order parameters for more than one degree of freedom.
25.
Various types of defects in the medium can be characterized by elements of various homotopy groups of the order parameter space.
26.
Aside from order parameters like the magnetization of a magnet, there are also topological quantities, like the winding number.
27.
That is, the fluctuation \ phi ( x ) in the order parameter corresponds to the order-order correlation.
28.
The complex nature of this order parameter allows for many parallels between nematic to smectic phase transitions and conductor to superconductor transitions.
29.
Also, by measuring the " penetration depth ", the symmetry of the HTS order parameter can be studied.
30.
It has been used in determining collective variables, i . e . order parameters, during phase transitions in the brain.
