Quantum Theory

Ahmed Almheiri, past Member (2017–22) in the School of Natural Sciences, has received a 2022 IUPAP Early Career Scientist Award in Particles and Fields “for substantial and impactful contributions to the understanding of black holes and quantum gravity, specifically related to the information paradox and its connection to quantum information theory and quantum error correction.”

"As theorists study black holes and other objects in AdS space, they keep learning Wheeler-esque lessons. One is that the connectivity of space — the ability to get from one place to another — seems to stem from particles on the boundary linked by correlations known as quantum entanglement."

"Natalie Paquette spends her time thinking about how to grow an extra dimension. Start with little circles, scattered across every point in space and time—a curlicue dimension, looped back onto itself. Then shrink those circles down, smaller and smaller, tightening the loop, until a curious transformation occurs: the dimension stops seeming tiny and instead becomes enormous, like when you realize something that looks small and nearby is actually huge and distant."

"Edward Witten has spent almost 50 years at the forefront of theoretical and mathematical physics. Here he describes how the LHC and other recent results have impacted his view on nature, and asks whether naturalness is still a useful guide for the field."
