Quantum dots as optimized chiral emitters for photonic integrated circuits
Jakub Rosiński, Michał Gawełczyk, Karol Tarnowski +3
Chiral coupling, which allows directional interactions between quantum dots (QDs) and photonic crystal waveguide modes, holds promise for enhancing the functionality of quantum pho…
Two-phonon propagation in a 4-level thermal quantum nanomachine
Y. Lai, C. McDwyer, P. Karwat +1
Acoustic waves, as science of sound, is an established field in physics. In analogy with light, engineers adapt tools from optic fields for manipulating sound waves to fight with c…
Near-field plasmonics for generation of phonon lasing in a thermal nanomachine
Paweł Karwat, Grzegorz Pasławski, Paul Damery +3
Recent advances in near-field plasmonic metamaterials, such as nanoresonators or transducers, have demonstrated the ability to generate localized fields of high intensity, and thus…
Phonon-assisted carrier tunneling in coupled quantum dot systems with hyperfine-induced spin flip
Paweł Karwat, Krzysztof Gawarecki, Paweł Machnikowski
We calculate the rates of phonon-assisted hyperfine spin flips during electron and hole tunneling between quantum dots in a self-assembled quantum dot molecule. We show that the hy…
Coherent phonon lasing in a thermal quantum nanomachine
Paweł Karwat, Doris E. Reiter, Tilmann Kuhn +1
The notion of nanomachines has recently emerged to engage and use collective action of ensembles of nanoscale components or systems. Here we present a heat-gradient driven nanomach…
Polaron resonances in two vertically stacked quantum dots
Paweł Karwat, Krzysztof Gawarecki, Paweł Machnikowski
In this work, we present a theoretical study of polaron states in a double quantum dot system. We present realistic calculations which combine 8 band \kp model, configuration inter…
Decay and persistence of spatial coherence during phonon-assisted relaxation in double quantum dots
Paweł Karwat, Paweł Machnikowski
We present a theoretical study of the evolution of spatial coherence during relaxation between delocalized exciton states in a pair of vertically stacked semiconductor quantum dots…
Phonon effects on the radiative recombination of excitons in double quantum dots
Pawel Karwat, Anna Sitek, Pawel Machnikowski
We study theoretically the radiative recombination of excitons in double quantum dots in the presence of carrier-phonon coupling. We show that the phonon-induced pure dephasing eff…
