The theoretical model for the microscopic coupling mechanism is still the subject of controversy, however. In ref. [1], we have presented a model including a density dependent coupling between opposite spin excitons which assumes that the interaction results in a renormalization of the matrix elements, dephasing rates and energies of the transition from the single-exciton state to the two-exciton state with respect to the corresponding quantities for the single exciton transitions. In contrast, Wang et al. claim that all experimental observations are explained by a density induced dephasing rate and that biexciton states play no role [2]. Here we present a new 3-pulse degenerate-four-wave-mixing (DFWM) configuration which is able to differentiate between pure local field effects and biexcitonic contributions to the time-integrated signal. Experiments were performed on an almost homogeneously broadened GaAs/Al0.3Ga0.7As single QW (well width 20 nm, photoluminescence line 0.3 meV, homogenous linewidth 0.15 meV) in the backward reflection geometry. The sample was cooled to 10 K and excited by a sequence of three pulses (1.1 ps duration) with equal intensity, wave vectors 𝑘→1,𝑘→2,𝑘→3 and delays τ12 and τ13 between the second and first and the third and first pulse, respectively. The signal was monitored in the direction 𝑘→𝑠=𝑘→1+𝑘→2−𝑘→3 which provides no signal for the chosen pulse length if local field and renormalization effects are negligible. The peak intensity of the time-integrated DFWM signal has been calculated by solving the optical Bloch for a system of two non-interacting two-level systems (2LS) with opposite circular polarization selection rules (local field effect) and for the renormalized four-level system (4LS) depicted in Fig. 1 which assumes the formation of biexcitons between excitons with opposite spins. The signal strength is proportional to the strength of the local field in the case of the 2LS and to the renormalization for the 4LS. The peak signal intensities expected for pure local field and pure biexction contributions are summarized in the second and third column of Table 1 for eight experimental configurations applying different linear and circularly polarized pulses. The values are normalized to the signal strength predicted for three parallel linearly polarized pulses.

This classification is crucial in the derivation of the analytical results but it also allows an efficient computation of the dominant Lyapunov exponent associated with each symmetry type.

The recognition architecture is based on an integrated statistical approach. We describe the characteristic features of the system as opposed to other systems: 1. the Viterbi criterion is consistently applied both in training and testing; 2. continuous mixture densities are used without tying or smoothing; 3. time-synchronous beam search in connection with a phoneme look-ahead is applied to a tree-organized lexicon.}}, author = {{Steinbiss, Volker and Ney, Hermann J. and Essen, Ute and Tran, Bach Hiep and Aubert, Xavier L. and Dugast, Christian and Kneser, Reinhard and Meier, Hans Günter and Oerder, Martin and Haeb-Umbach, Reinhold and Geller, Dieter and Hoellerbauer, W. and Bartosik, H.}}, journal = {{Speech Communication}}, title = {{{Continuous speech dictation - From theory to practice}}}, year = {{1995}}, } @techreport{13026, author = {{Hellebrand, Sybille and Wunderlich, Hans-Joachim}}, title = {{{Synthesis Procedures for Self-Testable Controllers}}}, year = {{1995}}, } @techreport{13027, author = {{Hellebrand, Sybille and Wunderlich, Hans-Joachim and Goncalves, F. and Paulo Teixeira, Joao}}, title = {{{Evaluation of Self-Testable Controller Architectures Based on Realistic Fault Analysis}}}, year = {{1995}}, } @techreport{13028, author = {{Hellebrand, Sybille and Herzog, Maik and Wunderlich, Hans-Joachim}}, title = {{{Partitioning of CMOS-Circuits for On-Chip IDDQ-Testing}}}, year = {{1995}}, } @inproceedings{15294, author = {{Hüllermeier, Eyke}}, booktitle = {{in Proceedings EUFIT-95 3rd European Congress on Intelligent Techniques and Soft Computing, Aachen, Germany}}, editor = {{Zimmermann, H.J.}}, pages = {{150--154}}, title = {{{Towards modelling of fuzzy functions}}}, year = {{1995}}, } @inproceedings{15295, author = {{Hüllermeier, Eyke}}, booktitle = {{in Proceedings ISFL-95 International Symposium on Logic, Zürich}}, pages = {{B49--B56}}, publisher = {{ICSC Academic Press}}, title = {{{Rule-based modelling in fuzzy simulation}}}, year = {{1995}}, } @inproceedings{15305, author = {{Hüllermeier, Eyke}}, booktitle = {{in Proceedings IMACS Symposium on Systems Analysis and Simulation, Berlin}}, pages = {{401--404}}, publisher = {{Gordon and Breach Publishers}}, title = {{{Fuzzy polynomial and spline interpolation}}}, year = {{1995}}, } @inproceedings{15272, author = {{Domik-Kienegger, Gitta and Owen, GS}}, booktitle = {{Proceedings of the Third Eurographics Workshop on Graphics and Visualization}}, title = {{{Education for Visualization-Activities of the ACM-SIGGRAPH Education Committee}}}, year = {{1995}}, } @book{1602, author = {{Krimphove, Dieter and Brehmer, Carsten}}, pages = {{49}}, publisher = {{FHTW Schriftenreihe}}, title = {{{Die Gründung einer GmbH}}}, volume = {{Nr. 13}}, year = {{1995}}, } @book{1603, author = {{Krimphove, Dieter}}, pages = {{59}}, publisher = {{FHTW Schriftenreihe}}, title = {{{Rechtliche Rahmenbedingungen des deutschen und internationalen Börsentermingeschäftes Ein Leitfaden für Banken, Sparkassen, Kreditinstitute, Anlagevermittler und Kunden mit Checklisten und Hinweisen zur Durchführung einer ordnungsgemäßen Anlageberatung }}}, volume = {{Nr. 14}}, year = {{1995}}, } @inbook{16236, author = {{Hüllermeier, Eyke}}, booktitle = {{Moderne Makroökonomie-Eine kritische Bestandsaufnahme}}, editor = {{Flemmig, J.}}, pages = {{413--454}}, publisher = {{Metropolis}}, title = {{{Konjunkturzyklen aufgrund von Investitionsinterdependenzen: Simulation und empirische Überprüfung}}}, year = {{1995}}, } @article{16243, author = {{Dohmeier-Fischer, Silvia and Krämer, Nicolai and Grützmacher, Hans- Friedrich}}, issn = {{1356-1049}}, journal = {{European Journal of Mass Spectrometry}}, title = {{{Rearrangement by intermediate ion/neutral complexes during the McLafferty fragmentation of unsaturated ketones}}}, doi = {{10.1255/ejms.154}}, year = {{1995}}, } @misc{13086, author = {{Hellebrand, Sybille and Reeb, Birgit and Tarnick, Steffen and Wunderlich, Hans-Joachim}}, keywords = {{WORKSHOP}}, title = {{{Pattern Generation for a Deterministic BIST Scheme}}}, year = {{1995}}, } @inproceedings{13469, author = {{Platzner, Marco and Rinner, Bernhard and Weiss, Reinhold }}, booktitle = {{Proceedings of the 3rd Euromicro Workshop on Parallel and Distributed Processing }}, pages = {{311--318}}, publisher = {{IEEE CS Press}}, title = {{{A Distributed Computer Architecture for Qualitative Simulation based on a Multi-DSP and FPGAs}}}, year = {{1995}}, } @inproceedings{13470, author = {{Brenner, Eugen and Ginthör-Kalcsics, Robert and Hranitzky, Robert and Platzner, Marco and Rinner, Bernhard and Steger, Christian and Weiss, Reinhold}}, booktitle = {{Proceedings of the 5th Annual Texas Instruments TMS320 Educators Conference}}, title = {{{High-Performance Simulators Based on Multi-TMS320C40}}}, year = {{1995}}, } @inproceedings{13471, author = {{Friedl, Gerald and Platzner, Marco and Rinner, Bernhard}}, booktitle = {{Proceedings of the EURO-PAR'95 International Conference on Parallel Processing}}, pages = {{695--698}}, publisher = {{Springer International Publishing}}, title = {{{A Special-Purpose Coprocessor for Qualitative Simulation}}}, year = {{1995}}, }
