In the Kohn-Sham orbital basis imaginary-time path integral for electrons in a semiconductor nanoparticle has a sufficiently mild fermion sign problem
to be amenable to evaluation by the standard stochastic methods. Utilizing output from the density functional theory simulations with
Perdew, Burke and Ernzerhof exchange-correlation functional we compute imaginary-time electron propagators in several silicon hydrogen-passivated
nanocrystals, such as Si35H36 and Si87H76, and extract energies of low-lying electron and hole levels. Our quasiparticle gap predictions are in good agreement with the results of recent G0W0 calculations by the Galli's group.
