Seminars

Speaker: Thomas Schwetz from Karlsruhe Institute of Technology (KIT) Venue&Time: Red Room / 3:00 PM Abstract: Recent results from cosmology place sever upper bounds on the sum of neutrino masses, starting to be in conflict with lower bounds from neutrino oscillations. If this neutrino tension persists, it may indicate new physics in cosmology and/or neutrino […]

Speaker: Álvaro de Rújula from IFT & CERN Venue & Time: Aula Polivalente UAM Abstract: Gamma-Ray Bursts (GRBs) and Cosmic Rays (CRs) are not difficult to comprehend. Quasars and micro-quasars are seen to emit highly relativistic “Cannonballs” (CBs), though the underlying mechanism remains unfathomable. The observation that core-collapse supernovae also emit CBs —plus some trivial […]

Speaker: Seung-Joo   Venue & Time: Tuesday, Nov. 4th / 17:00   Abstract: In this talk we will discuss spectral bounds in 6-dimensional N=(1,0) supergravity. Specifically, considering F-theory vacua on generic base surfaces, we will constrain the U(1) vector and the tensor sectors in turn, to present explicit spectral bounds on the respective sectors. Speculations […]

Speaker: Alex Gagliano (IAIFI/MIT) Venue&Time: Blue Room / 3:00 PM Abstract: The time-evolving night sky is rich with variable stars, supernovae, and merging neutron stars. Wide-field imaging surveys that monitor this variability produce gappy, multi-modal observations that demand scalable, uncertainty-aware models for physical inference. In this talk, I’ll survey my recent work in building machine […]

Speaker: Tarun Souradeep (Raman Research Institute, Bengaluru, India) Venue & Time: Red Room / 3:00 PM Abstract: The Cosmological Principle, a fundamental tenet of the 'standard model of cosmology’, predicates a statistically isotropic distribution of fluctuations in the measured cosmic microwave background (CMB) temperature and polarization sky maps. Enigmatic anomalies claimed in the WMAP and […]

Speaker: Anthony Zee (Kavli Institute for Theoretical Physics and the Department of Physics, University of California, Santa Barbara, CA, USA) Venue & Time: Red Room / 3:00 PM Abstract: I give an overview and appreciation of quantum field theory, the most precisely tested theory in physics. The talk is addressed to those without any knowledge of quantum field theory. It is based […]

Speaker: Alexander Zlokapa (MIT) Venue & Time: Red Room / 11:30 Abstract: In the classical setting, glassiness characterizes many natural problems (e.g., random k-SAT) and underlies average-case hardness by obstructing a family of "stable" classical algorithms (e.g., constant-time Langevin dynamics). In this work, we develop analogous quantum results. Our techniques, based on quantum optimal transport, […]

Speaker: Roberto Vega-Morales Venue&Time: Red Room / 15:00 Abstract: In this talk I will discuss constant classical electric fields and the Schwinger effect in de Sitter space, which has potential implications for magnetogenesis and inflationary dark matter production. I will first go through the conditions for sustaining a constant electric field in de Sitter space […]

Speaker: Miguel Zumalacárregui from Max Planck Institute for Gravitational Physics (Albert Einstein Institute). Venue&Time: Red Room / 3:00 PM Abstract: Gravitational lensing, the bending of light by gravity, is essential for interpreting astronomical observations and provides key insight into astrophysics, cosmology, and fundamental physics. A new frontier in gravitational lensing intersects with another key prediction […]
