Interference Effects on Kondo-Assisted Transport through Double Quantum Dots
Yoichi Tanaka, Norio Kawakami
We systematically investigate electron transport through double quantum dots with particular emphasis on interference induced via multiple paths of electron propagation. By means o…
Edge Singularity for the Optically Induced Kondo Effect in a Quantum Dot
T. Fujii, A. Furusaki, N. Kawakami +1
We analyze the optically induced Kondo effect in the absorption spectrum for a quantum dot with an even number of electrons, for which the Kondo effect does not occur in the ground…
Excitation Spectrum for Quantum Spin Systems with Ladder, Plaquette and Mixed-Spin Structures
Akihisa Koga, Norio Kawakami
By using the series expansion techniques, we study the excitation spectrum for the two-dimensional quantum spin systems with ladder, plaquette and mixed-spin structures. We calcula…
Mixed-spin cluster expansion for a quasi-one-dimensional Haldane system
Akihisa Koga, Norio Kawakami
We present a novel mixed-spin cluster expansion method for a quasi-one-dimensional Haldane system with bond alternation. By mapping the s=1 antiferromagnetic spin model on square a…
Comment on ``On the Renormalization of Conductance in Tomonaga-Luttinger Liquid''
Satoshi Fujimoto, Norio Kawakami
Recently Kawabata found that the conductance in Tomonaga-Luttinger (TL) liquids should not be renormalized if one incorporates the renormalization of applied fields correctly. This…
Chiral Tomonaga-Luttinger Liquids and the Calogero-Sutherland Model with Boundaries
Takashi Yamamoto, Norio Kawakami, Sung-Kil Yang
Applying boundary conformal field theory we study the low-energy critical behavior of the Calogero-Sutherland model of -type. The universality class of the model is found to…
