What's the order parameter in quasi crystals? Only the broken rotational symmetry?
Dickfore said:quasicrystals?! did you mean liquid crystals?
An order parameter in quasicrystals is a measure of the degree of long-range order in a quasicrystal structure. It is a mathematical quantity that characterizes the arrangement of atoms or particles in a quasicrystal, and can help to distinguish between different types of quasicrystals.
The order parameter in quasicrystals is determined through various experimental techniques such as X-ray diffraction, neutron scattering, and scanning tunneling microscopy. These techniques allow scientists to analyze the arrangement and symmetry of atoms in a quasicrystal and calculate the order parameter.
The order parameter is significant because it provides insight into the structure and properties of quasicrystals, which have unique and complex geometries that are not found in traditional crystals. Understanding the order parameter can help scientists to better understand the behavior and potential applications of quasicrystals.
Yes, the order parameter in quasicrystals can change under different conditions such as changes in temperature or pressure. This can affect the long-range order and symmetry of the quasicrystal, and can also impact its physical properties.
The order parameter in quasicrystals is different from that in traditional crystals because quasicrystals have non-periodic, aperiodic structures while traditional crystals have periodic structures. This results in different types of order parameters and different methods for determining and analyzing them.
