In the exterior region of a black hole, the bulk entropy $S_{bulk}(\rho)$ is regulated by a bulk UV cutoff, while the area term in the quantum extremal surface formula depends on N…

Let $\ket{D^N_1}$ denote the $N$-qubit Dicke state with one excitation, and let $(HC)_{1,2}$ denote circuits generated by Hadamard and controlled-not gates acting on qubits $1$ and…

Let $m$ and $n$ be the dimensions of the two subsystems, let $c=m/n$, and let $X$ be the standardized von Neumann entropy. Consider the fixed-trace ensemble of reduced density matr…

Area bound conjecture. There exists such a function $f$ for every gapped one-dimensional model, so the entanglement entropy is bounded in terms of the ratio of the Lieb–Robinson ve…
