Fine structure of excited excitonic states in quantum disks
M. M. Glazov, E. L. Ivchenko, R. v. Baltz +1
We report on a theoretical study of the fine structure of excited excitonic levels in semiconductor quantum disks. A particular attention is paid to the effect of electron-hole lon…

Exciton spin relaxation in single semiconductor quantum dots
E. Tsitsishvili, R. v. Baltz, H. Kalt
We study the relaxation of the exciton spin (longitudinal relaxation time ) in single asymmetrical quantum dots due to an interplay of the short--range exchange interaction…

Frequency Dependent Conductivity of the Fibonacci-Chain
Dieter Walther, Ralph v. Baltz
A real-space renormalization method for the frequency dependent conductivity of the periodic approximants of the Fibonacci chain is developed. This scheme is based on the known 2x2…
