Achieving coherent population transfer in the solid-state is challenging compared to atomic systems due to closely spaced electronic states and fast decoherence. Here, within an atomistic pseudopotential theory, we offer recipes for the stimulated Raman adiabatic passage in embedded silicon and germanium nanocrystals. The transfer efficiency spectra displays characteristic Fano resonances. By exploiting the Stark effect, we predict that transfer can be switched off with a dc voltage. As the…

Electron ground state g factor in embedded InGaAs quantum dots: An atomistic study
We present atomistic computations within an empirical pseudopotential framework for the electron $s$-shell ground state $g$-tensor of embedded InGaAs quantum dots (QDs). A large structural set


Tunneling induced transparency: Fano interference in intersubband transitions
We report the observation of tunneling induced transparency in asymmetric double quantum well structures. Resonant tunneling through a thin barrier is used to coherently couple the two upper states
Robust population transfer by stimulated raman adiabatic passage in a Pr3+:Y2SiO5 crystal.
We report on the experimental implementation of stimulated Raman adiabatic passage (STIRAP) in a Pr3+:Y2SiO5 crystal. Our data provide clear and striking proof for nearly complete population
Ultralong dephasing time in InGaAs quantum dots.
Between 7 and 100 K the polarization decay has two distinct components resulting in a non-Lorentzian line shape with a lifetime-limited zero-phonon line and a broadband from elastic exciton-acoustic phonon interactions.
Auger recombination and carrier multiplication in embedded silicon and germanium nanocrystals
For Si and Ge nanocrystals (NCs) embedded in wide band-gap matrices, Auger recombination (AR) and carrier multiplication (CM) lifetimes are computed exactly in a three-dimensional real space grid
Narrow luminescence linewidth of a silicon quantum dot.
Single-dot luminescence spectroscopy showed a continuous line narrowing towards lower temperatures with a linewidth as sharp as 2 meV at 35 K, proving the atomiclike emission from silicon quantum dots subject to quantum confinement.
Coherent population transfer among quantum states of atoms and molecules
The authors discuss the technique of stimulated Raman adiabatic passage (STIRAP), a method of using partially overlapping pulses (from pump and Stokes lasers) to produce complete population transfer
Coherent control of Rydberg states in silicon
This work demonstrates the coherent control of impurity wavefunctions in the most ubiquitous donor in a semiconductor, namely phosphorus-doped silicon, and adds coherent terahertz radiation, as a particularly precise regulator of orbitals in solids, to the list of controls, such as pressure and chemical composition, already familiar to materials scientists.
Theory of exciton dephasing in semiconductor quantum dots
We formulate a theory of exciton dephasing in semiconductor quantum dots extending the Huang-Rhys theory of F centers to include the mixing among the exciton state manifold through the
Coherent population transfer via the continuum.
It is suggested that a continuum can be used as an intermediary for a significant transfer of population from one discrete state to another discrete state in a stimulated Raman transition.
Stark effect, polarizability, and electroabsorption in silicon nanocrystals
Demonstrating the quantum-confined Stark effect (QCSE) in silicon nanocrystals (NCs) embedded in oxide has been rather elusive, unlike the other materials. Here, the recent experimental data from
