Reply to Comment on "Evolution of electronic structure of doped Mott insulator - reconstruction of poles and zeros of Green's function" [arXiv:0904.0454] by P. Phillips
Shiro Sakai, Yukitoshi Motome, Masatoshi Imada
In a recent Comment [arXiv:0904.0454] on our Letter [Phys. Rev. Lett. 102, 056404 (2009); arXiv:0809:0950], Phillips criticizes one specific issue discussed in our paper, concernin…
Evolution of electronic structure of doped Mott insulators - reconstruction of poles and zeros of Green's function
Shiro Sakai, Yukitoshi Motome, Masatoshi Imada
We study evolution of metals from Mott insulators in the carrier-doped 2D Hubbard model using a cluster extension of the dynamical mean-field theory. While the conventional metal i…
Itinerant ferromagnetism in the multiorbital Hubbard model: a dynamical mean-field study
Shiro Sakai, Ryotaro Arita, Hideo Aoki
In order to resolve the long-standing issue of how the itinerant ferromagnetism is affected by the lattice structure and Hund's coupling, we have compared various three-dimensional…
Quantum Monte Carlo study for multiorbital systems with preserved spin and orbital rotational symmetries
Shiro Sakai, Ryotaro Arita, Karsten Held +1
We propose to combine the Trotter decomposition and a series expansion of the partition function for Hund's exchange coupling in a quantum Monte Carlo (QMC) algorithm for multiorbi…
A new numerical algorithm for the double-orbital Hubbard model -- Hund-coupled pairing symmetry in the doped case
Shiro Sakai, Ryotaro Arita, Hideo Aoki
In order to numerically study electron correlation effects in multi-orbital systems, we propose a new type of discrete transformation for the exchange (Hund's coupling) and pair-ho…
