ITMP seminar
"Gravitational Waves from High Temperature Strings" by Dr. Ratul Mahanta, University of Winnipeg
Starts at 18:00
Dear Colleagues,
We are pleased to announce that the next ITMP seminar will be held on Wednesday, Mar 22, 18:00 (Moscow time). It will be organised via Zoom.
Speaker: Dr. Stefano Negro, New York University
Title: Deterministic chaos and Integrable Systems
Abstract: Integrability and chaos are commonly assumed to be incompatible concepts. There are important reasons for this. Prime amongst these is that integrable systems are not expected to thermalise since their phase space is entirely foliated by invariant tori thanks to the presence of a large amount of symmetries. On the other hand, a deep relation exists between thermalisation and chaotic behaviour, so much so that these concepts are commonly conflated. In this talk, starting from a definition of chaos as the property of the dynamics to map small intervals to unboundedly large ones, I will present some evidence that certain integrable systems, notably integrable field theories, present this behaviour. These results suggest the need for a more careful and deep understanding of the relationship between the concepts of chaos, thermalisation and integrability, in particular when the dimension of the systems’ phase spaces is infinite.
If you want to join the seminar please register here before 16:00, March 22 here.
