Title: From classical to quantum fields on causal sets Abstract: In this talk, I will give a brief review of algebraic classical and quantum field theory on causal sets. There are different approaches to quantise the classical fields,… Read More

Title: Search for Cosmic Strings Through Their Gravitational Wave Signals Abstract: We are currently witnessing the dawn of a new era in astrophysics and cosmology, started by the LIGO/Virgo observations of Gravitational Waves (GWs). In this talk I will… Read More

Title: Recent Developments in Quantum Cosmology Abstract: After a brief overview of the concepts behind quantum cosmology, with an emphasis on the no-boundary proposal for the very early universe, I will present the Kontsevich-Segal criterion. Kontsevich and Segal have… Read More

Title: Flavour Puzzles and the LHCb Experiment Abstract: Why is there no antimatter in the universe and why does nature provide us with three generations of similar fundamental fermions? These so-called flavour puzzles are among the most intriguing… Read More

Title: Covariant Loop Quantum Gravity and Cosmology Abstract: The covariant formulation of Loop Quantum Gravity dynamics, referred also as Spinfoam, provides currently the most complete formulation for a non-perturbative theory of quantum gravity. It is a formulation of the gravitational path integral as a… Read More

Title: Frame PB-groupoid of a VB-groupoid Abstract: Principal bundles are essential objects in gauge theories. A basic example of a principal bundle is the frames (or pointwise ordered basis) of a vector bundle on a manifold. Using this… Read More

Title: An Overview of the E11 Program Abstract: We will discuss the claim that the low energy effective action of the theory of strings and branes possesses an E11 Kac-Moody symmetry. We will show that a certain non-linear realization… Read More

Title: New Physics: Where Do We Stand? Abstract: This talk will be a discussion of our long-standing search for new phenomena in High-Energy Physics. We will describe the current situation, a decade after the Higgs discovery, and talk… Read More
