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.

Gulliver Seminar : Martin van Hecke (AMOLF, Univ. Leiden, Chaire Paris Science)

Lundi 30 mai 11:30-12:30 - Bibliothèque PCT - F3.04

Pathways and Information in Complex Matter

Collections of two-state hysteretic elements called hysterons describe the intricate pathways, hysteresis loops and memory effects observed in crumpled sheets and amorphous media. Such hysterons also naturally arise in many mechanical metamaterials and are then associated with buckling and snapping. Here we bridge these two fields, and explore, in experiments on corrugated sheets, on metamaterials, and in models, the pathways that these systems exhibit. In particular, we show that interactions between hysterons make these systems process information, and demonstrate examples of elementary mechanical computations such as counting and pattern matching.

General recommendations for the speakers

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.
