Abstract

Resonantly-excited photoluminescence (PL) of excitonic molecules with femtosecond resolution reveals a surprising initial transient characterized by a finite rise and an extremely fast non-exponential decay. We show that this initial transient stems from coherent quantum evolution of relative momentum of two excitons in the molecule, in sharp contrast to radiative dynamics of excitons. The initial transient also reflects a type of quantum beats that differ from the usual quantum beats in transient optical measurements.
