Kondo effects in a triangular triple quantum dot: NRG study in the whole region of the electron filling
Takahide Numata, Yunori Nisikawa, Akira Oguri +1
We study the low-energy properties of a triangular triple quantum dot connected to two non-interacting leads in a wide parameter range, using the numerical renormalization group (N…
Transport through a double quantum dot with interdot repulsion
Yunori Nisikawa, Akira Oguri
We study transport through a double quantum dot with interdot hopping , intradot repulsion and interdot repulsion , using the numerical renormalization group (NR…
Gate-voltage dependence of Kondo effect in a triangular quantum dot
T. Numata, Y. Nisikawa, A. Oguri +1
We study the conductance through a triangular triple quantum dot, which are connected to two noninteracting leads, using the numerical renormalization group (NRG). It is found that…
Momentum-dependent resonant inelastic X-ray scattering at the Si K edge of 3C-SiC: A theoretical study on a relation between spectra and valence band dispersion
Yunori Nisikawa, Muneharu Ibuki, Manabu Usuda
We theoretically demonstrate that a resonant inelastic x-ray scattering (RIXS) with a sizable momentum transfer can be utilized to study valence band dispersion for broad band mate…
Kondo screening of a high-spin Nagaoka state in a triangular quantum dot
Akira Oguri, Yunori Nisikawa, Yoshihide Tanaka +1
We study transport through a triangle triple quantum dot connected to two noninteracting leads using the numerical renormalization group (NRG). The triangle has a high-spin ground…
Numerical renormalization group approach to a quartet quantum-dot array connected to reservoirs:gate-voltage dependence of the conductance
Yunori Nisikawa, Akira Oguri
The ground-state properties of quartet quantum-dot arrays are studied using the numerical renormalization group (NRG) method with a four-site Hubbard model connected to two non-int…
