Magnetic Susceptibility of Multiorbital Systems
Katsunori Kubo, Takashi Hotta
Effects of orbital degeneracy on magnetic susceptibility in paramagnetic phases are investigated within a mean-field theory. Under certain crystalline electric fields, the magnetic…

Multipole ordering in f-electron systems
Katsunori Kubo, Takashi Hotta
In order to investigate multipole ordering in f-electron systems from a microscopic viewpoint, we study the so-called Γ_8 models on three kinds of lattices, simple cubic (sc), bcc,…

Analysis of f-p model for octupole ordering in NpO2
Katsunori Kubo, Takashi Hotta
In order to examine the origin of octupole ordering in NpO2, we propose a microscopic model constituted of neptunium 5f and oxygen 2p orbitals. To study multipole ordering, we deri…
