Large Magnetoresistance Induced by Quantum Charge Fluctuations in Magnetic Double Dots
L. Sheng, D. Y. Xing, D. N. Sheng
We study electron tunneling through two small ferromagnetic dots. Quantum charge fluctuations and interdot coupling make each Coulomb peak of the conductance at zero interdot coupl…

Anti-Resonance and the 0.7 Anomaly in Conductance through a Quantum Point Contact
Ye Xiong, X. C. Xie, Shi-jie Xiong
We investigate the transmission of electrons through a quantum point contact by using a quasi-one-dimensional model with a local bound state below the band bottom. While the comple…
