Magnetic field dependence of the energy of negatively charged excitons in semiconductor quantum wells
C. Riva, F. M. Peeters, K. Varga
A variational calculation of the spin-singlet and spin-triplet state of a negatively charged exciton (trion) confined to a single quantum well and in the presence of a perpendicula…
Excitons and charged excitons in semiconductor quantum wells
C. Riva, F. M. Peeters, K. Varga
A variational calculation of the ground-state energy of neutral excitons and of positively and negatively charged excitons (trions) confined in a single-quantum well is presented.…
Properties of few-electron artificial atoms
K. Varga, P. Navratil, J. Usukura +1
The spectra of quantum dots of different geometry (``quantum ring'', ``quantum cylinder'', ``spherical square-well'' and ``parabolic confinement'') are studied. The stochastic vari…
Borromean Binding of Three or Four Bosons
Steven Moszkowski, Sonia Fleck, Ali Krikeb +3
We estimate the ratio of the critical coupling constants and which are required to achieve binding of 2 or 3 bosons, respectively, with a short-rang…
Ground state of excitons and charged excitons in a quantum well
C. Riva, F. M. Peeters, K. Varga
A variational calculation of the ground state of a neutral exciton and of positively and negatively charged excitons (trions) in single quantum well is presented. We study the depe…
