IFISC Seminar on Wednesday May 10, 2023 at 14:30 Place: IFISC Seminar Room Title: Diversity in and of languages: how we can measure and model its emergence to unveil underlying social drivers Speaker: Thomas Louf, IFISC Abstract: Many are the ways in which human language varies and the social variables that give rise to these variations. The work I will present here shows how simple models can help build a good basis for understanding of these social mechanisms, and how online corpora from social media can be of great value to direct this modelling endeavour. We will first take a bird&#39;s-eye view to uncover the spatial arrangements of language groups in multilingual countries. We will show how bilingualism can not only belong to a transition period leading to language extinction, but also remain a stable state keeping alive a favoured minority language. We will then zoom in on English in the UK specifically, and gauge the existence of a link between the socio-economic background of individuals and their tendency to deviate from the standard form of their language. Our empirical results provide a more nuanced picture, also reflected in a model, that shows that social mixing plays a crucial role.

Talk on Friday May 05, 2023 at 11:00 Place: IFISC Seminar Room Title: Quantum Fisher Information and its dynamical nature Speaker: Matteo Scandi, ICFO Abstract: MdM Quantum Meeting The importance of the quantum Fisher information metric is testified by the number of applications that this has in very different fields, ranging from hypothesis testing to metrology, passing through thermodynamics. In this presentation, after a small technical introduction of the family of quantum Fisher information, I&#39;ll discuss a fact that was overseen in the literature, namely the inherently dynamical nature of Fisher information. This will be exemplified with three examples: first, the equivalence between positivity of a map and the contraction of Fisher information; second, the possibility of defining Markovianity (CP-divisibility) in the same manner; and finally, the definition of detailed balance as self-adjointness with respect to the Fisher information metric. The reference for the Markovianity part is: <a href="https://arxiv.org/pdf/2204.04072.pdf" target="_blank">https://arxiv.org/pdf/2204.04072.pdf</a>… Url event:https://ifisc.uib-csic.es/en/events/seminars/quantum-fisher-information-and-its-dynamical-natur/
