    1. 101. Emergent cosmology from matrix theory

      Strings and Quantum Gravity
      Plenary Talk

      Our universe has many puzzles. For example, we do not fully understand why we live in a four-dimensional universe out of the ten that string theory predicts. Additionally, many observed cosmological features, such as the scale-invariant spectrum of cosmological perturbations on large scales, cannot be explained by standard Big Bang physics alone. In this short presentation, I will discuss a...

    2. 72. Primordial Black Holes in 30 Min

      Relativity, Gravitation and Cosmology
      Plenary Talk

      Primordial black holes (PBHs) provide a unique link between the physics of the early Universe and present-day observations. Formed in the early Universe, PBHs have attracted considerable attention as candidates for dark matter (DM) and as potential sources of gravitational wave (GW) signals.

      In this talk, I will review the main mechanisms for PBH formation, their role as DM candidates, and...

    3. 99. Dynamical Algebra and Superintegrability: The Generic Model on the Two-Sphere
      Prof. Luc Vinet (Université de Montréal)

      Mathematical Physics
      Plenary Talk

      Superintegrable systems provide a natural laboratory in which to study symmetries, hidden structures and exactly solvable quantum models. A classical example is the hydrogen atom: the high degeneracy of its bound-state spectrum is explained by an o(4) symmetry, while the full collection of bound states can be organized using the larger dynamical algebra o(4,2), the Lie algebra of the conformal...

      Condensed Matter Theory
      Plenary Talk

      The past two decades have witnessed remarkable advances in our understanding of topological matter. What began as a framework for describing electronic phases of matter has evolved into a powerful organizing principle. Today, topological phenomena are explored not only in electronic materials, but also in photonic, magnonic, acoustic, and even classical systems.

      In this talk, I will...
