Cosmological Insights from Causal Set Theory
Yasaman Kouchekzadeh Yazdi - Dublin Institute For Advanced Studies
I will discuss some ideas from causal set theory that have bearing on open questions in cosmology. My primary focus will be dark energy and the early universe. I will also speculate about new ways these ideas may fit together.

Excitation of Ringdown Direct Waves
Sizheng Ma - Perimeter Institute for Theoretical Physics
It has recently been argued that the merger phase of gravitational waves from binary black hole coalescences contains not only quasinormal modes but also a newly identified component, the so-called “direct wave”. As the “last scream” of two merging black holes before they are silenced by the remnant…
The Quantum Computing and AI Frontier
Shayan Majidy - Harvard University
Quantum computers promise to simulate quantum systems and answer open questions across science from condensed matter and quantum chemistry to particle physics and quantum gravity. Two problems stand in the way: how to build them, and how to use them. Each brings hard optimisation, inference, and…

Directional Detection of Dark Matter
Yonatan Kahn - University of Toronto
As dark matter direct detection experiments push toward the neutrino fog, the daily modulation of the dark matter signal remains the final frontier needed to evade ubiquitous backgrounds. Directional detectors are required to observe this signal, and perhaps surprisingly, experiments sensitive to…
Combinatorics and Geometry of the Amplituhedron
Melissa Sherman-Bennett - University of California, Davis
The amplituhedron was introduced by Arkani-Hamed and Trnka as a geometric object which "encodes" scattering amplitudes in N=4 SYM theory. One of their motivations was the Britto-Cachazo-Feng-Witten (BCFW) recursion for amplitudes, which in particular produced many different formulas for the same…
