如下文章,似乎是翻轉(zhuǎn)了的。我沒具體看啊。 Dynamics of spin-flip photon-assisted tunneling(PHYSICAL REVIEW B 89, 075417 (2014)) We present time-resolved measurements of spin-flip photon-assisted tunneling and spin-flip relaxation in a doubly occupied double quantum dot. The photon-assisted excitation rate as a function ofmagnetic field indicates that spin-orbit coupling is the dominant mechanism behind the spin-flip under the present conditions. We are able to extract the resulting effective “spin-flip tunneling” energy, which is found to be three orders of magnitude smaller than the regular spin-conserving tunneling energy. We also measure the relaxation and dephasing times of a qubit formed out of two two-electron states with different spin and charge configurations. |
