Conservation of spin current
Jian Wang, Baigeng Wang, Wei Ren +1
The conventional definition of spin-current, namely spin density multiplied by the group velocity, is not a conserved quantity due to possible spin rotations caused by spin-orbit (…

Resonance transmission through a single atom
José-Luis Mozos, C. C. Wan, Gianni Taraschi +2
When a single atom is sandwiched in between two electrodes, an atomic tunneling device may be realized depending on the distance between the atom and the electrodes. We have perfor…

A local approach for global partial density of states
Jian Wang, Qingrong Zheng, Hong Guo
To apply the scattering approach for the problem of AC transport through coherent quantum conductors, various partial density of states must be evaluated. If the global partial den…
