Interannual variability in Asian Summer Monsoon rainfall features two modes that are correlated with concurrent and preceding winter ENSO, respectively. The latter post-ENSO effect is especially puzzling. The lecture explains how coupled ocean-atmospheric modes affect the Asian Summer Monsoon.

The string-net model introduced by M. Levin and X.-G. Wen in 2005 allows one to generate all (bosonic) topological  achiral phases in two dimensions. In this talk, I will explain how to compute the exact partition function of this model and discuss the finite-temperature properties of several quantities such as the topological mutual information. These results show that, in this context, topological order can only survive up to a temperature which depends on the system size and goes to zero in the thermodynamical limit.

We consider a gas of non-interacting fermions that is released from a box into the vacuum. This provides a simple analytically tractable model that reproduces many features of the Page curve characterizing the evolution of entanglement entropy during evaporation of a black hole. Apart from the entropy we consider several other physical observables and show that generalized hydrodynamics provides a rather surprisingly accurate description of the quantum dynamics.
