Correlations in multiband quantum systems

Project funded by Research Council of Finland, grant 349313. Participating organisations named by the source: Aalto University. Funded amount: EUR 558,297, as stated by the source. Runs 2022-09-01 to 2026-08-31. Keywords: Physical sciences. Source: OpenAIRE Graph, from the funder's project data (collected by OpenAIRE on 2026-07-23); national funding data, not CORDIS. Abstract given by the source: This project targets to discover how the non-trivial multiband nature of a periodic lattice system affects bosonic correlations. The project combines quantum many-body theory research with optical experiments in nanostructured materials. Optical processing could offer low-energy-cost solutions for information technology whose global energy consumption is growing at an unsustainable rate, but advances have remained hindered partly by the weakness of matter-mediated effective interactions between photons. The key idea of the project is that the multiband lattice design may allow even weak photon-photon interactions to lead to strong effects on the system behavior. The expected breakthroughs are fundamental knowledge revealing how bosonic correlations can be enhanced by the lattice design, and the demonstration of the results in an optical system. The results can open the door for full-scale utilization of photons in all-optical classical and quantum information processing.
