Eigenstate thermalization hypothesis and approximate quantum error correction [PDF]
Journal of High Energy Physics, 2019 Abstract The eigenstate thermalization hypothesis (ETH) is a powerful conjecture for understanding how statistical mechanics emerges in a large class of many-body quantum systems. It has also been interpreted in a CFT context, and, in particular, holographic CFTs are expected to satisfy ETH.

Thermal Transport Across Graphene Step Junctions [PDF]
, 2018 Step junctions are often present in layered materials, i.e. where single-layer regions meet multi-layer regions, yet their effect on thermal transport is not understood to date. Here, we measure heat flow across graphene junctions (GJs) from monolayer to
