Minimal Models of Entropic Order
Xiaoyang Huang, Zohar Komargodski, Andrew Lucas +2
Due to entropic effects, it is possible that generic high-energy states of a quantum or classical system are ordered. This leads to spontaneous symmetry breaking at arbitrarily hig…
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…
