Systematic Control of Carrier Doping without Disorder at Interface of Oxide Heterostructures
Motoaki Hirayama, Masatoshi Imada
We propose a method to systematically control carrier densities at the interface of transition-metal oxide heterostructures without introducing disorders. By inserting non-polar la…
Comparison of Ab initio Low-Energy Models for LaFePO, LaFeAsO, BaFe2As2, LiFeAs, FeSe and FeTe: Electron Correlation and Covalency
Takashi Miyake, Kazuma Nakamura, Ryotaro Arita +1
Effective low-energy Hamiltonians for several different families of iron-based superconductors are compared after deriving them from the downfolding scheme based on first-principle…
Transition from Band insulator to Bose-Einstein Condensate superfluid and Mott State of Cold Fermi Gases with Multiband Effects in Optical Lattices
Ryota Watanabe, Masatoshi Imada
We study two models realized by two-component Fermi gases loaded in optical lattices. We clarify that multi-band effects inevitably caused by the optical lattices generate a rich s…
Unconventional quantum criticality emerging as a new common language of transition-metal compounds, heavy-fermion systems, and organic conductors
Masatoshi Imada, Takahiro Misawa, Youhei Yamaji
We analyze and overview several different unconventional quantum criticalities. One origin of the unconventionality is the proximity to first-order transitions. The border between…
Ab-initio procedure for effective models of correlated materials with entangled band structure
Takashi Miyake, Ferdi Aryasetiawan, Masatoshi Imada
We present a first-principles method for deriving effective low-energy models of electrons in solids having entangled band structure. The procedure starts with dividing the Hilbert…
Electronic and magnetic properties of metallic phases under coexisting short-range interaction and diagonal disorder
Hiroshi Shinaoka, Masatoshi Imada
We study a three-dimensional Anderson-Hubbard model under the coexistence of short-range interaction and diagonal disorder within the Hartree-Fock approximation. We show that the d…
