CMSP Seminar (Joint ICTP/SISSA Statistical Physics): Spin chains with “medium-range” interactions and cellular automata
room 138 in SISSA via Bonomea (and via Zoom)

Abstract:
We will consider spin chains with “medium-range” interactions, i.e. beyond the interaction of neighbouring nodes. At first glance, such systems are a natural and trivial generalization of the Heisenberg magnet, thus they have been little explored in the past. However, they are of significant interest due to their connection to cellular automata on the one hand and the obtaining of new solutions to the Yang-Baxter equation on the other. We will separately discuss the connection of such a generalization with the TT-bar deformation in QFT.
