Ab initio Derivation of Low-energy Model for Iron-Based Superconductors LaFeAsO and LaFePO
Kazuma Nakamura, Ryotaro Arita, Masatoshi Imada
Effective Hamiltonians for LaFeAsO and LaFePO are derived from the downfolding scheme based on first-principles calculations and provide insights for newly discovered superconducti…
Quantum Mott Transition and Superconductivity
Masatoshi Imada
The gas-liquid transition is a first-order transition terminating at a finite-temperature critical point with diverging density fluctuations. Mott transition, a metal-insulator tra…
Superconductivity Driven by the Interband Coulomb Interaction and Implications for the Superconducting Mechanism of MgB2
Masatoshi Imada
Superconducting mechanism mediated by interband exchange Coulomb repulsion is examined in an extended two-band Hubbard models with a wide band crossing the Fermi level and coexisti…
Pseudogap and Superconducting Fluctuations in High-Tc Cuprates
Shigeki Onoda, Masatoshi Imada
We analyze pseudogap phenomena widely observed in the underdoped cuprates. We assume the existence of a strong d-wave pairing force competing with antiferromagnetic(AFM) fluctuatio…
Quantum Effects in Resistance-Shunted Josephson Junctions
Takeo Kato, Masatoshi Imada
Thermodynamics and transport properties of resistance-shunted Josephson junctions are studied theoretically in the tight-binding limit E_C/E_J<<1, where E_C and E_J are a charging…
