Dynamics of the Anderson impurity model: benchmarking a non-adiabatic exchange-correlation potential in time-dependent density functional theory
Niklas Dittmann, Nicole Helbig, Dante M. Kennes
In this comparative study we benchmark a recently developed non-adiabatic exchange-correlation potential within time-dependent density functional theory (TDDFT) (Phys.\ Rev.\ Lett.…

Finite-frequency noise of interacting single-electron emitters: spectroscopy with higher noise harmonics
Niklas Dittmann, Janine Splettstoesser
We derive the symmetrized current-noise spectrum of a quantum dot, which is weakly tunnel-coupled to an electron reservoir and driven by a slow time-dependent gate voltage. This se…

Equilibrium finite-frequency noise of an interacting mesoscopic capacitor studied in time-dependent density functional theory
Niklas Dittmann, Janine Splettstoesser, Nicole Helbig
We calculate the frequency-dependent equilibrium noise of a mesoscopic capacitor in time-dependent density functional theory (TDDFT). The capacitor is modeled as a single-level qua…
