Phonon-assisted decoherence and tunneling in quantum dot molecules
quantum dot phonon decoherence tunneling

We study the influence of the phonon environment on the electron dynamics in a doped quantum dot molecule.A non-perturbative quantumkinetic theory based on correlation expansion is used in order to de...
Controlling phonon entanglement and squeezing via one- and two-phonon interference
Controlling phonon entanglement squeezing two-phonon interference

When ultrafast laser pulse strikes the crystal with a van Hove singularity in the phonon density of states, it creates a pair of anti-correlated in wave vector acoustic phonons. As a result, the atomi...
