Cluster-size dependence in cellular dynamical mean-field theory
Shiro Sakai, Giorgio Sangiovanni, Marcello Civelli +3
We examine the cluster-size dependence of the cellular dynamical mean-field theory (CDMFT) applied to the two-dimensional Hubbard model. Employing the continuous-time quantum Monte…
Ab initio Evidence for Strong Correlation Associated with Mott Proximity in Iron-based Superconductors
Takahiro Misawa, Kazuma Nakamura, Masatoshi Imada
We predict that iron-based superconductors discovered near d6 configuration (5 Fe 3d orbitals filled by 6 electrons) is located on the foot of an unexpectedly large dome of correla…
Mott Transition and Phase Diagram of -(BEDT-TTF)2Cu(NCS)2 Studied by Two-Dimensional Model Derived from Ab initio Method
Hiroshi Shinaoka, Takahiro Misawa, Kazuma Nakamura +1
We present an ab initio analysis for the ground-state properties of a correlated organic compound -(BEDT-TTF)2Cu(NCS)2. First, we derive an effective two-dimensional low-energy…
Theory of pseudogap and superconductivity in doped Mott insulators
Masatoshi Imada, Youhei Yamaji, Shiro Sakai +1
Underdoped Mott insulators provide us with a challenge of many-body physics. Recent renewed understanding is discussed in terms of the evolution of pole and zero structure of the s…
{\it Ab initio} Studies on the Interplay between Spin-Orbit Interaction and Coulomb Correlation in SrIrO and BaIrO
R. Arita, J. Kuneš, A. V. Kozhevnikov +2
{\it Ab initio} analyses of AIrO (A=Sr, Ba) are presented. Effective Hubbard-type models for Ir 5 manifolds downfolded from the global band structure are solved…
Stability of Unconventional Superconductivity on Surfaces of Topological Insulators
Yuto Ito, Youhei Yamaji, Masatoshi Imada
Superconductivity on the surface of topological insulators is known to be anisotropic and unconventional in that the symmetry is the mixture of s-wave and nodeless p-wave component…
