中文摘要	based on our recent work on quantum transport [x. q. li , phys. rev. b 71, 205304 (2005)], we show how an efficient calculation can be performed for the current noise spectrum. compared to the classical rate equation or the quantum trajectory method, the proposed approach is capable of tackling both the many-body coulomb interaction and quantum coherence on an equal footing. the practical applications are illustrated by transport through quantum dots. we find that this alternative approach is in a certain sense simpler and more straightforward than the well-known landauer-buttiker scattering matrix theory.
