Integrable Impurity Model with Spin and Flavour: Model Inspired by Resonant Tunneling in Quantum Dot
Osamu Tsuchiya, Ikuo Ichinose, Yasuyuki Kayama
We introduce an integrable impurity model in which both electrons and impurity have spin and flavour degrees of freedom. This model is a generalization of the multi-channel Kondo m…

Low-energy excitations in 2-leg and 3-leg quantum spin ladders
Ikuo Ichinose, Yasuyuki Kayama
Low-energy excitations in spin 1/2 antiferromagnetic Heisenberg spin ladders are studied by bosonization and gauge theoretical description. It is explicitly shown that zero modes i…
