Three-dimensional electronic structures and the metal-insulator transition in Ruddlesden-Popper iridates
A. Yamasaki, H. Fujiwara, S. Tachibana +19
In this study, we systematically investigate 3D momentum()-resolved electronic structures of Ruddlesden-Popper-type iridium oxides SrIrO using soft-x-…
Electron-hole doping asymmetry of Fermi surface reconstructed in a simple Mott insulator
Yoshitaka Kawasugi, Kazuhiro Seki, Yusuke Edagawa +6
It is widely recognised that the effect of doping into a Mott insulator is complicated and unpredictable, as can be seen by examining the Hall coefficient in high cupra…
From a quasimolecular band insulator to a relativistic Mott insulator in systems with a honeycomb lattice structure
Beom Hyun Kim, Tomonori Shirakawa, Seiji Yunoki
The orbitals of an edge-shared transition-metal oxide with a honeycomb lattice structure form dispersionless electronic bands when only hopping mediated by the edge-sharin…
Ground state phase diagram of the triangular lattice Hubbard model by density matrix renormalization group method
Tomonori Shirakawa, Takami Tohyama, Jure Kokalj +2
Two-dimensional density-matrix renormalization group method is employed to examine the ground state phase diagram of the Hubbard model on the triangular lattice at half filling. Th…
Density matrix renormalization group study in energy space for a single-impurity Anderson model and an impurity quantum phase transition
Tomonori Shirakawa, Seiji Yunoki
The density matrix renormalization group method is applied to obtain the ground state phase diagram of the single impurity Anderson model on the honeycomb lattice at half filling.…
Emergence of massless Dirac quasiparticles in correlated hydrogenated graphene with broken sublattice symmetry
Kazuhiro Seki, Tomonori Shirakawa, Qinfang Zhang +2
Using the variational cluster approximation (VCA) and the cluster perturbation theory, we study the finite temperature phase diagram of a half-depleted periodic Anderson model on t…
