The role of dephasing in some recent theories of quantum localization

Paul E. Parris, Philip Phillips

Research output: Contribution to journalArticle


We consider the transport of electrons or excitons through a random environment in the presence of constant site off-diagonal dephasing processes. It is shown that dephasing of this form will always defeat Anderson localization at long times. Some recent theories of quantum localization which depend upon such dephasing processes are, therefore, seen to be inconsistent.
