First-Principles Approach to Spin Excitations in Noncollinear Magnetic Systems
Hsiao-Yi Chen, Ryotaro Arita, Yusuke Nomura
We present a first-principles method based on density functional theory and many-body perturbation theory for computing spin excitations in magnetic systems with noncollinear spin…
Luttinger surface and exchange splitting induced by ferromagnetic fluctuations
Motoharu Kitatani, Yusuke Nomura, Shiro Sakai +1
Ferromagnetism in the single-orbital Hubbard model, which contains only local Coulomb repulsion and no explicit ferromagnetic exchange interactions, has been extensively studied. H…
Symmetry-breaking perturbations in the Jahn-Teller-Hubbard model
Natsuki Okada, Tatsuya Miki, Yusuke Nomura +2
We study the effect of symmetry-breaking perturbations in the multiorbital Hubbard model coupled to anisotropic Jahn-Teller phonons, which is relevant for the description of fuller…
Strong-coupling high- superconductivity in doped correlated band insulators
Yusuke Nomura, Motoharu Kitatani, Shiro Sakai +1
We explore the superconducting properties of the bilayer Hubbard model, which exhibits a high transition temperature () for an pairing, using a cluster extensi…
