Spectral broadening of optical transitions at tunneling resonances in InAs/GaAs coupled quantum dot pairs
P. Kumar, C. Jennings, M. Scheibner +3
We report on linewidth analysis of optical transitions in InAs/GaAs coupled quantum dots as a function of bias voltage, temperature, and tunnel coupling strength. A significant lin…
Geometry-induced circulation of local photonic transport in a triangular metastructure
Palak Dugar, Michael Scheibner, Chih-Chun Chien
A geometry-based mechanism for inducing circulation of photons is illustrated by a metastructure consisting of quantum dots arranged in a triangle coupled to photonic structures. T…
Tunable current circulation in triangular quantum-dot metastructures
Chen-Yen Lai, Massimiliano Di Ventra, Michael Scheibner +1
Advances in fabrication and control of quantum dots allow the realization of metastructures that may exhibit novel electrical transport phenomena. Here, we investigate the electric…
Entanglement Dynamics of Molecular Exciton States in Coupled Quantum Dots
Cameron Jennings, Michael Scheibner
We theoretically model the electronic dynamics of a coupled quantum dot pair in a static electric field. We then investigate the possibility of polarization-entangled photon emissi…
Electric field tunable exchange interaction in InAs/GaAs coupled quantum dots
Kushal C. Wijesundara, Mauricio Garrido, Swati Ramanathan +4
Spin manipulation in coupled quantum dots is of interest for quantum information applications. Control of the exchange interaction between electrons and holes via an applied electr…
Characterization of the Shell Structure in Coupled Quantum Dots through Resonant Optical Probing
Mauricio Garrido, Kushal C. Wijesundara, Swati Ramanathan +4
Excited states in single quantum dots (QDs) have been shown to be useful for spin state initialization and manipulation. For scalable quantum information processing it is necessary…
