CONDENSED MATTER SYSTEMS. “This diversity of phenomena can be attributed to the multiple degrees of freedom available to the electronic system that, in itself or in conjunction to lattice degrees of freedom, can have access to entangled spin and orbital states.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

ELECTRON CHARGES. “In particular, the electron clouds around nuclei in crystalline materials can be systematically characterized by using the multipole expansion.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

OPPOSITES. “The opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth.”(Niels Bohr). https://lnkd.in/e3-J7hXM View in LinkedIn

ORBITAL ASYMMETRY. “Since electrons on filled atomic shells lead only to spherical charge distributions, the electrons in open shells are responsible for the anisotropic charge and spin distributions and thus for the eventual appearance of multipolar order.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

HEN’S TEETH. “It turns out, however, that the appearance of true multipolar order, that is, of rank higher than dipolar order, is actually rare in solid state compounds.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

THE RARE MULTIPOLARS. “Thus far, true multipolar order has been discovered, or predicted, for about a dozen crystalline materials.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

F ELECTRONS AND MULTIPOLARS. “These compounds have in common that the exotic multipolar electric or magnetic distribution occurs on the lanthanide or actinide ion and are thus generated by the f electrons.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

F ELECTRON ORBITALS. “The electron orbital letters go in the order s, p, d, f, g, h, i, j, etc. At the fourth and higher levels, there are seven f orbitals in addition to the 4s, 4p, and 4d orbitals. Counting the 4s, 4p, and 4d orbitals, this makes a total of 16 orbitals in the fourth level. They have even more complicated shapes. s, p, d, and f orbitals are available at all higher energy levels as well.” (Great graphics). https://lnkd.in/eaQ4p_NY View in LinkedIn

FIRST PRINCIPLES. “To treat multipolar degrees of freedom from first principles, it is thus needed to treat strong local electron correlations, spin–orbit interaction, and the multi-orbital f electron character on an equal footing.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

APPLICABILITY. “Recently, first-principles electronic structure calculations have been shown to be suitable for investigation of the multipole ordered states in correlated solid state materials.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn
