COMPETITION

The Serbian Academy of Nonlinear Sciences (SANS) announces a competition for progress in the understanding of postvibrational interactions (Epstein effect). The award consists of 1,000 euros and a corresponding SANS diploma. Nominations with appropriate attachments are received until end of October 2025 to the email: sann.akademija@gmail.com. The prize will be awarded to the best published work that represents significant progress in the theoretical understanding of postvibrational interactions. The result of the competition will be announced in December 2025.

Description. There exists the modulating effect of postvibrational interactions which has been discovered and deeply discussed on experimental level in https://doi.org/10.3390/sym15101914https://doi.org/10.3390/sym16080958. Some attempts to understand it on theoretical level have been done in https://doi.org/10.3390/sym16050572; https://link.springer.com/article/10.1007/s11182-024-03127-y. Still consistent physical explanation of this so-called Epstein effect is not satisfactory. It is  expected that some mathematical physics  theoretical model to explain the phenomenon will be proposed and awarded.
