Abstract: In this talk we will describe categorical symmetries of spin chains from the viewpoint of subalgebras of the quasi-local algebra of observables in the infinite volume limit. In particular, we provide formal axioms for a subalgebra to give...

Abstract: We consider dispersive bounds on Wilson coefficients of scalar effective field theories (EFT) coupled to gravity in various spacetime dimensions, including the contributions from graviton loops to the sum rules at low energies. Dispersion...

Abstract: Astrophysical events such as core-collapse supernovae (SN) and neutron star mergers offer unique opportunities to explore physics beyond the Standard Model. In this seminar, I will provide an overview of the mechanisms underlying these...

Abstract: It is well-known that amplitudes in Yang-Mills theory are severely constrained by the requirement of gauge invariance. In this talk, I will explore two aspects of YM amplitudes where (surface) gauge invariance plays a paramount role. First...

Abstract: Holographic duality posits that quantum gravity under the assumption of certain boundary conditions is described by strongly interacting quantum matter. In the context of a theory-experiment consortium (Lausanne-Geneva-Trento-Zürich), we...

Abstract: In this talk, I will present a Hamiltonian approach to show decay for massless Vlasov fields on the exterior of black hole backgrounds. Vlasov fields are transported along the geodesic flow, and so, the existence of trapped geodesics is an...
