Trapping Flux in Metals
Zohar Komargodski, Fedor K. Popov
We report on a new flux quantization phenomenon in metals. We study the response of normal metals to the presence of localized magnetic flux. We find that, due to backreaction effe…
Defect Anomalies, a Spin-Flux Duality, and Boson-Kondo Problems
Zohar Komargodski, Fedor K. Popov, Brandon C. Rayhaun
We show that the infrared phases of certain line defects in 2+1d quantum field theories are determined by anomalies, including anomalies in the space of defect coupling constants,…
Do null defects dream of conformal symmetry?
Rajeev S. Erramilli, Justin Kulp, Fedor K. Popov
We initiate the study of null line defects in Lorentzian conformal field theories in various dimensions. We show that null lines geometrically preserve a larger set of conformal is…
Entropic Order
Yiqiu Han, Xiaoyang Huang, Zohar Komargodski +2
Ordered phases of matter, such as solids, ferromagnets, superfluids, or quantum topological order, typically only exist at low temperatures. Despite this conventional wisdom, we pr…
On Real Time Dynamics of Large Models
Fedor K. Popov
We analyze the real-time dynamics of the large vector model, focusing on heavy states with energies of the order . In this regime, we demonstrate that interactions become su…
