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...

72. Primordial Black Holes in 30 Min

Dr Encieh Erfani (Perimeter Institute for Theoretical Physics)

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...

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...
