Title: The initial pump-probe polarization anisotropy of colloidal PbS quantum dots

Abstract

Pump-probe polarization anisotropy measurements with 15 fs pulses are employed to investigate the electronic structure of PbS quantum dots. Here, the initial anisotropy at the bandgap is anomalously low (<0.1) and suggests large electronic couplings.
