Morphic properties, tensor parameters, order parameters and domain states

T, U, S, V: property tensors; TOP: designation of tensor or order parameter; [\Gamma]: representation of G expressing the transformation properties of TOP. The terms `full' and `partial' were introduced by Aizu (1970a[link]).

Morphic propertyTOP[\Gamma ]Stabilizer of TOPDomain states
Spontaneous components of tensor T [\varphi] [{\Gamma}_{\varphi} ] [F_1] Principal (full) in tensor T
Spontaneous components of tensor U [\psi] [{\Gamma}_{\varphi} ] [F_1] Principal (full) in tensor U
Spontaneous components of tensor S [\sigma] [{\Gamma}_{\sigma} ] [F_1] Principal (full) in tensor S
Spontaneous components of tensor V [\lambda] [{\Gamma}_{\lambda} ] [L_1, \ F_1\subset L_1\subset G] Degenerate (partial) in tensor V
Primary order parameter [\eta] [\Gamma_{\eta}] [{\cal F}_1] Basic (microscopic)
Pseudoproper order parameter [\zeta] [\Gamma_{\eta}] [{\cal F}_1] Basic (microscopic)
Secondary (improper) order parameter [{\xi}] [{\Gamma}_{\xi} ] [{\cal L}_1, {\cal F}_1\subset{\cal L}_1\subset{\cal G} ] Secondary (improper) microscopic
