Atomistic theory of electronic and optical properties of InAsP/InP nanowire quantum dots
Moritz Cygorek, Marek Korkusinski, Pawel Hawrylak
We present here an atomistic theory of the electronic and optical properties of hexagonal InAsP quantum dots in InP nanowires in the wurtzite phase. These self-assembled quantum do…
Role of excited states in the dynamics of excitons and their spins in diluted magnetic semiconductors
Florian Ungar, Moritz Cygorek, Vollrath Martin Axt
We theoretically investigate the impact of excited states on the dynamics of the exciton ground state in diluted magnetic semiconductor quantum wells. Exploiting the giant Zeeman s…
Emission-frequency separated high quality single-photon sources enabled by phonons
Michael Cosacchi, Florian Ungar, Moritz Cygorek +2
We demonstrate theoretically that the single-photon purity of photons emitted from a quantum dot exciton prepared by phonon-assisted off-resonant excitation can be significantly hi…
Phonon-induced enhancement of photon entanglement in quantum dot-cavity systems
Tim Seidelmann, Florian Ungar, Andreas M. Barth +4
We report on simulations of the degree of polarization entanglement of photon pairs simultaneously emitted from a quantum dot-cavity system that demand revisiting the role of phono…
Origins of overshoots in the exciton spin dynamics in semiconductors
Florian Ungar, Moritz Cygorek, Vollrath Martin Axt
We investigate the origin of overshoots in the exciton spin dynamics after resonant optical excitation. As a material system, we focus on diluted magnetic semiconductor quantum wel…
From strong to weak temperature dependence of the two-photon entanglement resulting from the biexciton cascade inside a cavity
Tim Seidelmann, Florian Ungar, Moritz Cygorek +4
We investigate the degree of entanglement quantified by the concurrence of photon pairs that are simultaneously emitted in the biexciton-exciton cascade from a quantum dot in a cav…
