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

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

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

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

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

OFF-DIAGONAL RESPONSES. “As the multipole classification scheme can be generalized to systems characterized by a specific point group symmetry, multipole theory is becoming used for the classification of off-diagonal response phenomena, such as the electric-magnetic effect and the anomalous Hall effect in antiferromagnets.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

OPEN AVENUE. “If a resonantly driven many-body system experiences temporal disorder, the many-body localization phenomenon in a time crystalline structure can be investigated.” https://lnkd.in/e5UXiem5 View in LinkedIn

PUSHING THE ENVELOPE. “We have seen that a resonantly driven single particle can behave in the time domain like an electron moving in a space crystal. One may raise the question if many-body condensed matter phenomena can be observed in the time dimension too?” https://lnkd.in/e5UXiem5 View in LinkedIn
