Continuous Mott Transition in a Two-Dimensional Hubbard Model
Yuki Yanagi, Kazuo Ueda
We investigate nonmagnetic metal-insulator transition in the 1/5-depleted square lattice Hubbard model at half-filling within the 8-site cellular dynamical mean field theory. We fi…
SU(3) Dirac electrons in the 1/5-depleted square-lattice Hubbard model at 1/4 filling
Yasufumi Yamashita, Masaki Tomura, Yuki Yanagi +1
We investigate the magnetic and metal-insulator (M-I) phase diagram of the 1/5-depleted square-lattice Hubbard model at 1/4 filling by the mean-field approximation. There exist thr…
Dimensional Reduction and Odd-Frequency Pairing of the Checkerboard-Lattice Hubbard Model at 1/4-Filling
Yuki Yanagi, Yasufumi Yamashita, Kazuo Ueda
The ferromagnetism of the checkerboard lattice Hubbard model at quarter filling is one of the few exact ferromagnetic ground states known in the family of Hubbard models. When the…
Electric Dipolar Kondo Effect Emerging from Vibrating Magnetic Ion
Takashi Hotta, Kazuo Ueda
When a magnetic ion vibrates in a metal, it inevitably introduces a new channel of hybridization with conduction electrons and in general, the vibrating ion induces electric dipole…
Effect of Anharmonicity on the Kondo Phenomena of a Magnetic Ion Vibrating in a Confinement Potential
Satoshi Yashiki, Kazuo Ueda
Effect of anharmonicity of a cage potential for a magnetic ion vibrating in a metal is investigated by the numerical renormalization group method. The cage potential is assumed to…
Nonlinear Transport through Quantum Dots Studied by the Time-Dependent DMRG
Shunsuke Kirino, Kazuo Ueda
Recent developments on studies of transport through quantum dots obtained by applying the time-dependent density matrix renormalization group method are summarized. Some new aspect…
