21 May 2013 | Abstract: | The adiabatic theorem addresses the dynamics of an interested instantaneous
eigenstate. Multiple eigenstates are involved in the dynamical process when the
adiabatic conditions are not satisfied. We use a Feshbach P-Q partitioning
technique to derive a one-component integral-differential equation. The
resultant equation properly traces the footprint of the interested eigenstate.
We analyze the equation in general and with examples, and surprisingly find an
anomalous phenomenon: particular white noises can enhance and even induce
adiabaticity. The predicted process may occur sponta- neously in nature. In
addition, these noises can also help to shorten the total duration of dynamic
processes such as adiabatic quantum computing. | Source: | arXiv, 1305.4845 | Services: | Forum | Review | PDF | Favorites |
