Long-lived Nonlinear Oscillatory States in Interacting Relativistic Bose-Einstein Condensates
Leone Di Mauro Villari, Ian Galbraith, Fabio Biancalana
In this paper we study a mean field model for the dynamics of an interacting Bose-Einstein condensate in two dimensional pseudo-relativistic materials. This model is relatively sim…
Coulomb effects in the absorbance spectra of two-dimensional Dirac materials
Leone Di Mauro Villari, Ian Galbraith, Fabio Biancalana
A wide range of materials like graphene, topological insulators and transition metal dichalcogenides (TMDs) share an interesting property: the low energy excitations behave as Dira…
Tuning biexciton binding and anti-binding in core/shell quantum dots
Peter G. McDonald, Edward J. Tyrrell, John Shumway +2
We use a path integral quantum Monte Carlo method to simulate excitons and biexcitons in core shell nanocrystals with Type-I, II and quasi-Type II band alignments. Quantum Monte Ca…
Lateral spatial switching of excitons using vertical electric fields in semiconductor quantum rings
Peter G McDonald, John Shumway, Ian Galbraith
We study the response of exciton complexes in semiconductor quantum rings to vertical electric fields, using path integral quantum Monte Carlo simulations. The interaction of a ver…
Ultrafast pump-probe dynamics in ZnSe-based semiconductor quantum-wells
Henni Ouerdane, George Papageorgiou, Ian Galbraith +2
Pump-probe experiments are used as a controllable way to investigate the properties of photoexcited semiconductors, in particular, the absorption saturation. We present an experime…
Photon emission induced by elastic exciton--carrier scattering in semiconductor quantum wells
H. Ouerdane, R. Varache, M. E. Portnoi +1
We present a study of the elastic exciton--electron () and exciton--hole () scattering processes in semiconductor quantum wells, including fermion exchange effects. The…
