 We study the fluctuation entropy for two-dimensional matter systems with an internal symmetry coupled to Jackiw--Teitelboim(JT) gravity joined to a Minkowski region. The fluctuation entropy is the Shannon entropy associated with probabilities of...

I will discuss recent work on a Hayden & Preskill like setup for both maximally chaotic and sub- maximally chaotic quantum field theories. I will discuss computations of various quantum information measures on the boundary that tell us when a...

In an ordinary quantum field theory, the "split property" implies that the state of a system can be specified independently on a bounded subregion of a Cauchy slice and its complement. This property does not hold for theories of gravity. It can be...

In this talk I will discuss models of two-dimensional gravity that resolve the factorization puzzle and have a discrete spectrum, whilst retaining a semiclassical description. A novelty of these models is that they contain non-trivially correlated...
