A semiconductor photon-pair source based on a polariton cascade
Karol Kawa
We present a theoretical study of a semiconductor photon-pair source based on a radiative cascade enabled by a permanent exciton dipole. The source consists of a GaAs quantum dot p…
Triplet-assisted leakage during singlet-triplet qubit readout with a quantum point contact
Karol Kawa
Quantum point contact readout theory for singlet-triplet qubits in a lateral double quantum dot is extended by including tunneling of triplet configurations into a higher-energy le…
Exciton Diffusion in a Quantum Dot Ensemble
Karol Kawa, Paweł Machnikowski
In this theoretical study, we explore Förster resonant energy transfer of a single exciton within a two-dimensional array of self-assembled quantum dots arranged randomly on a circ…
Coherence limitations in the optical control of the singlet-triplet qubit in a quantum dot molecule
Karol Kawa, Tilmann Kuhn, Paweł Machnikowski
We analyze the optically driven dynamics of a qubit implemented on a singlet-triplet subspace of two-electron states in a self-assembled quantum dot molecule. We study two possible…
Spread of Correlations in Strongly Disordered Lattice Systems with Long-Range Coupling
Karol Kawa, Paweł Machnikowski
We investigate the spread of correlations carried by an excitation in a 1-dimensional lattice system with high on-site energy disorder and long-range couplings with a power-law dep…
Diffusion of excitation and power-law localization in long-range-coupled strongly disordered systems
Karol Kawa, Paweł Machnikowski
We investigate diffusion of excitation in one- and two-dimensional lattices with random on-site energies and deterministic long-range couplings (hopping) inversely proportional to…
Spin-orbit-induced hole spin relaxation in a quantum dot molecule: the effect of - coupling
Karol Kawa, Paweł Machnikowski
We study the effect of the coupling between the hole shell of one quantum dot and the shell in the other dot forming a quantum dot molecule on the spin relaxation between t…
