Gulliver seminars take place on Mondays at 11:30 AM in the F304 room, and typically last one hour including questions. The seminars are in English, and the scientific topics are mainly those studied in the laboratory.
Séminaire GULLIVER : Vincenzo Vitelli (University of Chicago)
The interaction between a peregrine falcon and a dove is visibly non-reciprocal. What happens to the well established framework of hydrodynamics and phase transitions in non-reciprocal systems far from equilibrium ? In this talk, I will first answer this question by looking at three archetypal topics in soft matter : active solids, flocking and interfacial dynamics. Simple demonstrations with robots will be presented along with naturally occurring phenomena from various domains of science that share a common feature : reciprocity has no reason to exist.
Next, I will discuss how to incorporate non-reciprocal individual preferences of decision-making organisms into a hydrodynamic theory. I will describe a data-driven pipeline that links micromotives to macrobehavior by augmenting hydrodynamics with socioeconomic utility functions that describe individual preferences. I will highlight how to use data-driven tools to not only validate the hypotheses underlying the hydrodynamic construction, but also to infer microscopic preferences using human residential dynamics in the US as a case study.

Gulliver seminar : Matthew Turner (Warwick University, UK)
Lundi 13 mai de 11h30 à 12h30 - C162
Collective motion & environmental path entropy
We discuss a “bottom up” model for collective motion. This involves moving agents that re-orientate so as to maximise a measure of the entropy of their environment in the future. We discuss why such principles might confer fitness on rather general grounds. We then discuss the dynamics that arise from them that lead (...)
The audience is often heterogeneous - because of the wide range of scientific topics covered in the lab - so planning a talk for a broader audience would be preferred. The seminar is in English, and speakers are thus invited to prepare their slides in English.
The seminar starts at 11:30 AM. The speaker is asked to arrive in the lab at least 15 minutes in advance to set up their computer. The talks last typically 45 minutes, and are followed by a discussion time.
