(When) Do Inflationary Perturbations Classicalize?
Aurora Ireland - Stanford University
According to the standard paradigm, all structure in the universe originated as quantum fluctuations amplified by an early epoch of cosmic inflation. If any trace of these quantum origins were to survive, it would offer a unique window into quantum physics at otherwise inaccessible scales. While… -

Quantum algebras from generalized Poisson sigma models
Keyou Zeng - Harvard University
Poisson sigma models sit at the intersection of deformation theory, geometry, and quantum field theory; specifically, the perturbative expansion of the two-dimensional Poisson sigma model with boundary is known to recover Kontsevich’s deformation quantization formula. In this talk, I introduce a… -

A Perturbative Window into Asymptotic Safety
Yannick Kluth - University of Toronto
Asymptotic safety offers a compelling UV completion of quantum gravity through a non-trivial UV fixed point. Evidence for this has so far come predominantly from the functional renormalization group. In this talk, I explore a complementary perturbative approach, which offers manifest gauge… -

Black Hole Sensitivities in Lorentz-Violating Gravity
Andrew Kovachik - McMaster Univresity
Lorentz-violating theories modify the effective point-particle description of black holes through sensitivity parameters that describe their response to motion relative to a preferred frame. We calculate these sensitivities for Schwarzschild and Reissner–Nordström black holes in both Einstein-aether… -

Reshaping Metrology with Quantum Information Processing
Sisi Zhou - Perimeter Institute for Theoretical Physics
Quantum metrology studies how precisely physical parameters can be estimated using quantum systems. In this talk, I will illustrate how modern quantum technologies, including quantum error correction and quantum learning, can help approach the ultimate limits of quantum sensing and reshape the…
