We consider the extent to which symmetry eigenvalues reveal the topological character of bands. Specifically, we compare distinct atomic limit phases (band representations) that share the same irreducible representations (irreps) at all points in the

The symmetry-mode analysis of a structural phase transition involves the use of methods of the representation theory of space groups. The aim of the paper is to present an alternative approach for the determination of the primary and secondary symmet

A systematic procedure for the determination of supergroups of space groups is developed and used for the search of pseudosymmetric structures within crystal structure databases. The method is applied to P212121 structures listed in the Inorganic Cry

A crystal structure is usually described as the union of sets of symmetrically equivalent atoms, i.e. as the union of orbits. During a continuous or nearly continuous phase transition, symmetrically equivalent atoms of a crystal structure may become

The Landau-Ginzburg-Wilson Hamiltonian is a function that relates Landau's phenomenological theory of magnetic phase transitions to the quantum mechanics of a microscopic spin model. The authors study how the symmetry of the system under consideratio
