Modelling exciton-phonon interactions in optically driven quantum dots
Ahsan Nazir, Dara P. S. McCutcheon
We provide a self-contained review of master equation approaches to modelling phonon effects in optically driven self-assembled quantum dots. Coupling of the (quasi) two-level exci…
Temperature-dependent Mollow triplet spectra from a single quantum dot: Rabi frequency renormalisation and sideband linewidth insensitivity
Yu-Jia Wei, Yu He, Yu-Ming He +7
We investigate temperature-dependent resonance fluorescence spectra obtained from a single self-assembled quantum dot. A decrease of the Mollow triplet sideband splitting is observ…
Ground state and dynamics of the biased dissipative two-state system: Beyond variational polaron theory
Ahsan Nazir, Dara P. S. McCutcheon, Alex W. Chin
We propose a ground-state ansatz for the Ohmic spin-boson model that improves upon the variational treatment of Silbey and Harris for biased systems in the scaling limit. In partic…
A general approach to quantum dynamics using a variational master equation: Application to phonon-damped Rabi rotations in quantum dots
Dara P. S. McCutcheon, Nikesh S. Dattani, Erik M. Gauger +2
We develop a versatile master equation approach to describe the non-equilibrium dynamics of a two-level system in contact with a bosonic environment, which allows for the explorati…
Quantum dot Rabi rotations beyond the weak exciton-phonon coupling regime
Dara P. S. McCutcheon, Ahsan Nazir
We study the excitonic dynamics of a driven quantum dot under the influence of a phonon environment, going beyond the weak exciton-phonon coupling approximation. By combining the p…
Separation-dependent localization in a two-impurity spin-boson model
Dara P. S. McCutcheon, Ahsan Nazir, Sougato Bose +1
Using a variational approach we investigate the delocalized to localized crossover in the ground state of an Ohmic two-impurity spin-boson model, describing two otherwise non-inter…
