Real-time effective-action approach to the Anderson quantum dot

Show other versions (1)

The nonequilibrium time evolution of an Anderson quantum dot is investigated. The quantum dot is coupled between two leads forming a chemical-potential gradient. We use Kadanoff-Baym dynamic equations within a nonperturbative resummation of the s-channel bubble chains. The effect of the resummation...
