Magnetic tuning of the tunnel coupling in an optically active quantum dot molecule
Frederik Bopp, Charlotte Cullip, Christopher Thalacker +15
Self-assembled optically active quantum dot molecules (QDMs) allow the creation of protected qubits via singlet-triplet spin states. The qubit energy splitting of these states is d…
The crux of using the cascaded emission of a 3-level quantum ladder system to generate indistinguishable photons
Eva Schöll, Lucas Schweickert, Lukas Hanschke +13
We investigate the degree of indistinguishability of cascaded photons emitted from a 3-level quantum ladder system; in our case the biexciton-exciton cascade of semiconductor quant…
Raman spectrum of Janus transition metal dichalcogenide monolayers WSSe and MoSSe
Marko M. Petrić, Malte Kremser, Matteo Barbone +7
Janus transition metal dichalcogenides (TMDs) lose the horizontal mirror symmetry of ordinary TMDs, leading to the emergence of additional features, such as native piezoelectricity…
Atomistic defect states as quantum emitters in monolayer MoS
Julian Klein, Michael Lorke, Matthias Florian +12
Quantum light sources in solid-state systems are of major interest as a basic ingredient for integrated quantum device technologies. The ability to tailor quantum emission through…
Fluctuation induced luminescence sidebands in the emission spectra of resonantly driven quantum dots
Fabrice P. Laussy, Vase Jovanov, Elena del Valle +9
We describe how complex fluctuations of the local environment of an optically active quantum dot can leave rich fingerprints in its emission spectrum. A new feature, termed "Fluctu…
