Samuel J. Garratt

Samuel J. Garratt is a theoretical physicist currently serving as an Associate Research Scholar at Princeton University since 2025. Previously, he held a Moore Fellowship at the University of California, Berkeley (2021-2025), and pursued his DPhil at the University of Oxford (2017-2021) under John Chalker. He earned his BA + MSci from the University of Cambridge (2013-2017), conducting research with Zoran Hadzibabic.

His research bridges many-body quantum mechanics, quantum simulation, and classical computation. Key interests include measurement-induced effects in quantum systems, entanglement dynamics, and connections between quantum error correction, statistical mechanics, and condensed matter physics. He explores phenomena like Goldstone modes, slow relaxation in spin systems, and the complexity of simulating quantum systems classically.

His recent publications focus on post-measurement dynamics, quantum Monte Carlo methods, entanglement in thermal states, and Floquet systems. These works intersect quantum information theory, condensed matter, and computational physics, with applications to quantum computing and error correction.

• Moore Fellowship (2021-2025)

Since September 2021, Garratt has advised undergraduate and graduate research students. He previously held teaching roles at St. Hugh's College, Oxford (stipendiary lecturer, tutor), and organized classes for MMathPhys students. He has presented talks at institutions including ETH Zurich, MIT, and Caltech, and participated in workshops on quantum chaos, many-body systems, and NISQ technologies.
