Speaker: Bernardo Fraiman (IFT) Venue&Time: Red Room / 12:00 Abstract: For non-compact, locally symmetric moduli spaces M, the set of geodesics and the geometry of the boundary can be completely characterised using group theory. Under the assumption that M is "compactifiable" and some mild conditions on the spectrum of states, we prove the SDC for […]
Speaker: Le-Chen Qu (IFT) Venue&Time: Grey Room 3 / 11:30 Abstract: We establish a precise correspondence between Krylov complexity and Nielsen complexity in quantum many-body systems. By identifying the Krylov basis with the generators of elementary gates in Nielsen's geometric framework, the Krylov complexity of precursor operators acquires a geometric interpretation as the length of […]

Speaker: Georgina Staudt (Max Planck Institute Munich) Venue&Time: Red Room / 12:00 Abstract: We investigate the deformability of the Veneziano amplitude. If string theory is the unique theory of quantum gravity, the tree level amplitudes of weak coupling limits should be non-deformable. We make progress in this direction for tachyon-free superstring theories by deriving a […]
Pau Garcia Romeu (IFT) will present Renormalization and Effective Lagrangians by Joseph Polchinski. Venue&Time: Blue Room / 17:00 Abstract: There is a strong intuitive understanding of renormalization, due to Wilson, in terms of the scaling of effective lagrangians. We show that this can be made the basis for a proof of perturbative renormalization. We first […]

Speaker: Pablo Blanco Mas (IFT) Venue & Time: Grey Room 3 / 15:00 Abstract: We study how coherent scattering of a background gas off an atom (or other matter) interferometer can lead to enhanced signals from phase shifts and contrast loss. We focus on the inclusion of realistic features of atom interferometers such as finite temperature, […]
