Balancing error budget for fermionic k-RDM estimation
Nayuta Takemori, Yusuke Teranishi, Wataru Mizukami +1
The reduced density matrix (RDM) is crucial in quantum many-body systems for understanding physical properties, including all local physical quantity information. This study aims t…
Anomalously large spin-dependent electron correlation in nearly half-metallic ferromagnet CoS
Hirokazu Fujiwara, Kensei Terashima, Junya Otsuki +19
The spin-dependent band structure of CoS which is a candidate for a half-metallic ferromagnet was investigated by both spin- and angle-resolved photoemission spectroscopy and t…
Supercurrent Distribution in Real-Space and Anomalous Paramagnetic Response in a Superconducting Quasicrystal
Takumi Fukushima, Nayuta Takemori, Shiro Sakai +2
We theoretically study the real-space distribution of the supercurrent that flows under a uniform vector potential in a two-dimensional quasiperiodic structure. This is done by con…
Superconductivity on a Quasiperiodic Lattice: Extended-to-Localized Crossover of Cooper Pairs
Shiro Sakai, Nayuta Takemori, Akihisa Koga +1
We study a possible superconductivity in quasiperiodic systems, by portraying the issue within the attractive Hubbard model on a Penrose lattice. Applying a real-space dynamical me…
Local Electron Correlations in a Two-dimensional Hubbard Model on the Penrose Lattice
Nayuta Takemori, Akihisa Koga
We study electron correlations in the half-filled Hubbard model on two-dimensional Penrose lattice. Applying the real-space dynamical mean-field theory to large clusters, we discus…
Low temperature properties of the fermionic mixtures with mass imbalance in optical lattice
Nayuta Takemori, Akihisa Koga
We study the attractive Hubbard model with mass imbalance to clarify low temperature properties of the fermionic mixtures in the optical lattice. By combining dynamical mean-field…
