We review the recent advances and current challenges in the field of strong spin-orbit
coupled Kitaev materials, with a particular emphasis on the physics beyond the exactly …

Complex oxides with 4 d and 5 d transition-metal ions recently emerged as a new paradigm
in correlated electron physics, due to the interplay between spin–orbit coupling and electron …

We discuss phenomena arising from the combined influence of electron correlation and spin-
orbit coupling (SOC), with an emphasis on emergent quantum phases and transitions in …

YbMgGaO 4, a structurally perfect two-dimensional triangular lattice with an odd number of
electrons per unit cell and spin-orbit entangled effective spin-1/2 local moments for the Yb …

The continuous miniaturization of charge-based electronic devices and overcoming the
bottleneck of Moore's law have driven the rapid growth of spintronics, spintronics operates …

In Mott insulators with the t 2 g 4 electronic configuration such as of Re 3+, Ru 4+, Os 4+,
and Ir 5+ ions, spin-orbit coupling dictates a Van Vleck–type nonmagnetic ground state with …

Motivated by the recent experimental progress on the strong spin-orbit-coupled rare-earth
triangular antiferromagnet, we analyze the highly anisotropic spin model that describes the …

Since the discovery of perovskite materials with the general chemical formula ABX3 in 1839,
research on perovskite materials has drawn exponentially greater attention, owing to their …

We consider a class of d-and f-electron systems in which dipolar-octupolar Kramers
doublets arise on the sites of the pyrochlore lattice. For such doublets, two components of …

The Jahn-Teller effect is one of the most fundamental phenomena important not only for
physics but also for chemistry and material science. Solving the Jahn-Teller problem and …
