Two-orbital Kondo effect in quantum dot coupled to ferromagnetic leads
Hitoshi Yoshizumi, Kensuke Inaba, Tomoko Kita +1
We study the Kondo effect of a two-orbital vertical quantum dot (QD) coupled to two ferromagnetic leads by employing an equation of motion method. When the ferromagnetic leads are…
Spatial fluctuations of spin and orbital in two-orbital Hubbard model
Tomoko Kita, Takuma Ohashi, Sei-ichiro Suga
We investigate the quasiparticle dynamics in the two-orbital Hubbard model on the square lattice at quarter filling by means of the cellular dynamical mean field theory. We show th…
Three-orbital Kondo effect in single quantum dot system with plural electrons
Tomoko Kita, Rui Sakano, Takuma Ohashi +1
We study the Kondo effect and related transport properties in orbitally degenerate vertical quantum dot systems with plural electrons. Applying the non-crossing approximation to th…
Thermopower, figure of merit, quantum dot, Kondo effect, orbital degrees of freedom
Rui Sakano, Tomoko Kita, Norio Kawakami
We study the thermopower and some related transport quantities due to the orbital Kondo effect in a single quantum dot system with a finite value of Coulomb repulsion by means of t…
Thermopower of Kondo Effect in Single Quantum Dot Systems with Orbital at Finite Temperatures
R. Sakano, T. Kita, N. Kawakami
We investigate the thermopower due to the orbital Kondo effect in a single quantum dot system by means of the noncrossing approximation. It is elucidated how the asymmetry of tunne…
Non-Crossing Approximation Study of Multi-Orbital Kondo Effect in Quantum Dot Systems
Tomoko Kita, Rui Sakano, Takuma Ohashi +1
We study the three-orbital Kondo effect in quantum dot (QD) systems by applying the non-crossing approximation to the three-orbital Anderson impurity model. By investigating the tu…
