Dynamical Coulomb Blockade and the Derivative Discontinuity of Time-Dependent Density Functional Theory
Dynamical Coulomb Blockade and the Derivative Discontinuity of Time-Dependent Density Functional Theory
The role of the discontinuity of the exchange-correlation potential of density functional theory is studied in the context of electron transport and shown to be intimately related to Coulomb blockade. By following the time evolution of an interacting nanojunction attached to biased leads, we find that, instead of evolving to …
