Quantum coherence and Kondo effect in multi quantum dot systems
Xi Dai, T. K. Ng
The quantum interference effect among coupled identical quantum dots is studied in the present paper in the limit of strong intra-dot Coulomb interaction. When the average electron…

This paper has been withdrawn by the authors. We are in the process of obtaining more data and will resubmit a modified manuscript in the near future.
Schwinger boson mean field theory of the Heisenberg Ferrimagnetic Spin Chain
Congjun Wu, Bin Chen, Xi Dai +2
The Schwinger boson mean field theory is applied to the quantum ferrimagnetic Heisenberg chain. There is a ferrimagnetic long range order in the ground state. We observe two branch…
The Effective Theory of Hole Doped Spin-1 Chain
Xi Dai, Bin Chen, Zhao-Bin Su
An effective theory for the hole doped spin-1 antiferromagnetic chain is proposed in this paper. The two branches of low energy quasipaticle excitation is obtained by the diagrammi…
