Low-energy excitation spectra in the excitonic phase of cobalt oxides
Tomoki Yamaguchi, Koudai Sugimoto, Yukinori Ohta
We study the excitonic phase and low-energy excitation spectra of perovskite cobalt oxides. Constructing the five-orbital Hubbard model defined on the three-dimensional cubic latti…

Orbital diamagnetic susceptibility in excitonic condensation phase
Koudai Sugimoto, Yukinori Ohta
We study the orbital diamagnetic susceptibility in excitonic condensation phase using the meanfield approximation for a two-band model defined on a square lattice. We find that, in…
