BBN circa 2022: New Physics hints from the Early Universe?
Bang Nucleosynthesis (BBN) is one of the greatest outcome of the Standard Model of Particle Physics when put next to ΛCDM cosmology. In this talk, I will first review the...

Krembil Foundation elevates its commitment to Canadian-based breakthroughs
When the Krembil Foundation first partnered with Perimeter Institute in 2013, its goal was to spur scientific advances at the world’s largest independent centre for theoretical physics, introducing prestigious named...
: From black holes to the Big Bang: astrophysics and cosmology with gravitational waves and their electromagnetic counterparts
The growing catalog of gravitational-wave signals from compact object mergers has allowed us to study the properties of black holes and neutron stars more precisely than ever before and has...

The Complexity and (Un)Computability of Quantum Phase Transitions
The phase diagram of a material is of central importance in describing the properties and behaviour of a condensed matter system. Indeed, the study of quantum phase transitions has formed...

Anakin's story from Star Wars soundtracks
We shall explore the genius of John Williams when it comes to tell stories through his soundtracks. Since the full analysis of Anakin’s life is still a work in progress...

Locality bounds on quantum dynamics with measurements
In non-relativistic systems, the Lieb-Robinson Theorem imposes an emergent speed limit (independent of the relativistic limit set by c), establishing locality under unitary quantum dynamics and constraining the time needed...

From learners to creators: Perimeter’s ninth PSI class graduates
After 10 months clambering up a steep learning curve, the 2017/18 class of Perimeter Scholars International (PSI) this week reached the pinnacle, and the view was grand. Together, the class...
Holographic scattering from quantum error-correction
We revisit the problem of how interactions emerge in quantum gravity. Namely, we show that bulk scattering of multiple particles in the AdS space requires multipartite entanglement on the boundary...

Astrophysical breakthroughs earn Brockhouse Canada Prize
For their game-changing contributions to the hunt for distant explosions called fast radio bursts, the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Collaboration – including Perimeter’s Kendrick Smith and Ue-Li Pen...
