Group-theoretical analysis of possible structural phase transitions in the high-temperature superconductors

A group-theoretical analysis is performed for the complete condensation of order parameters at structural phase transitions (SPT's) in the high-temperature superconductors belonging to the D 17 4h -14/mmm space group in the high-symmetry phase. As a rule, such transformations are due to a succe...
