Fluorescent semiconductor quantum dots (QDs) are frequently used in conjunction with biological molecules in a wide variety of applications. A negative 30-nm shift in QD emission has been observed upon binding CdSe QDs to DNA origami, a large scaffolded double-stranded DNA molecule. This paper effectively explains the observed emission shift by modeling the effect of the electric field generated by...
We derive a local equation of motion for the electronic single-particle density matrix in the presence of one- as well as two-body scattering processes. This is done by applying the mean-field approximation to the many-electron dynamics obtained via a recently proposed Markov limit, able to furnish many-body Lindblad-type scattering superoperators. The resulting time evolution at finite/high carrier...
With the technical progress of radio-frequency setups, high frequency quantum transport experiments have moved from theory to the lab. So far the standard theoretical approach used to treat such problems numerically — known as Keldysh or NEGF (Non Equilibrium Green's Functions) formalism — has not been very successful mainly because of a prohibitive computational cost. We propose a reformulation of...
