SUMMARY:Geza Mark (Centre for Energy Research\, University of Budapest).
DESCRIPTION:Titre : Information\, energy\, and entropy — what is the price of knowledge? \nAbstract : \nGlobal energy consumption of artificial intelligence already has reached the total electricity consumption of a medium-sized country. Hence\, it is timely to look at this question from the viewpoint of physics. First we ask whether there is a theoretical minimum of energy needed for information processing. Then\, we investigate\, how far are the AI systems from that limit and compare this to biological systems. Finally\, we explore the theoretical possibilities for increasing energy efficiency and discuss which of these are technologically feasible in the near future. \nThis seminar will take place in Room CH11 at the Faculty of Sciences.

SUMMARY:Iva Bačić (University of Belgrade)
DESCRIPTION:Title: Phase locking and multistability in the topological Kuramoto model on cell complexes \nAbstract: Higher-order interactions fundamentally shape collective dynamics in oscillator networks. The topological Kuramoto model captures these effects by extending synchronization models to include interactions between cells of arbitrary dimension within simplicial and cell complexes. We introduce the topological nonlinear Kirchhoff conditions to characterize all phase-locked states of the topological Kuramoto model. These states are organized by winding numbers associated with generalized independent cycles\, which quantify how phases wind around these cycles. Using rings\, Platonic solids\, and regular simplices as illustrative examples\, we uncover a universal rule: boundaries must have at least five elements for multistability to arise. We further find that independent winding numbers associated with lower- and higher-dimensional boundaries generate cascades of multistability across dimensions. These results show how the topology and boundary structure of cell complexes influence phase locking and multistability\, and provide a general framework for collective dynamics on cell complexes. \nThis seminar will take place in Room S08 at the Faculty of Sciences.
