| contents | We overview recent developments of electronic orderings and associated cross correlations in condensed matter physics based on a complete set of multipole representations (electric, magnetic, electric toroidal, and magnetic toroidal multipoles) with distinct space-time inversion symmetries. By means of the symmetry-adapted complete basis set in any physical Hilbert space including atomic and cluster degrees of freedom, it provides a unified description of electronic orderings, deformations of band structures, cross correlations, and transport properties in solids. We review that a multipole representation is a powerful tool to attain a comprehensive understanding of various electronic properties and physical phenomena observed in materials. We also demonstrate how to identify active multipoles and expected physical phenomena in real materials with several examples. Our review would serve as a solid foundation for future studies toward observations and identifications of unknown electronic phases and their related physical phenomena. |
