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…

Modified Double Exchange Model with Novel Spin and Orbital Coupling: Phase Diagram of The Manganites
L. Sheng, C. S. Ting
From a general model of the Mn oxides R_{1-x}A_{x}MnO_3, we derive an effective Hamiltonian in the low-energy subspace using the projection operator method, in which a novel coupli…
