Title: Generalized second law for non-minimally coupled matter theories
Abstract: In this talk, I will give a brief overview of the generalized second law (GSL) of black hole thermodynamics. In particular, we will see how the GSL works out for non-minimally coupled matter theories within the context of higher curvature gravity theories. Previous proofs in the literature have extensively addressed the GSL in various gravity theories, but they have uniformly assumed that matter sectors couple minimally to gravity. In this presentation, we will explore a straightforward generalization of the GSL to scenarios involving non-minimally coupled matter, specifically scalar fields, within an effective field theory framework.

Title: Relativistic operational quantum reference frames
Abstract: I will be sharing some recent insights related to applying the operational approach to quantum reference frames (QRFs) in relativistic contexts. I will begin by briefly reviewing the principles of operational QRFs to then apply them in the context of the Poincare group and discuss the emerging notion of relational local observables. This perspective can be further generalized to gauge theories by replacing the Poincare group by an arbitrary principal bundle. In this context, the concepts of external frame transformations, gauge-invariance and diff-invariance can be understood in a relational and operational manner. If time allows, I will also mention work in progress on how indefinite geometries can be incorporated in this picture, how far we in establishing this approach as a relational and mathematically sound foundation for QFT, and its connections to quantum measurement theory in this context. I would also be happy to exchange some ideas about how the `thermal modular type-reduction’ phenomena could be seen from this perspective.
