Let a frustration-free FBI Hamiltonian be a many-body Hamiltonian whose ground-state energy is attained when each positive-semidefinite local term is minimized, and let its Hartree…

Frobenius light-cone conjecture. The bound above can be replaced by

Let $A$ be a few-body observable, and let $|E_k\rangle$ be an eigenvector of the Hamiltonian of a large interacting many-body system with energy $E_k$. Eigenstate thermalisation hy…

Consider a many-particle system placed in a heat bath and represent its equilibrium state as a Hilbert-space vector. The authors assume that the many-particle system and its dynami…

Let $H^L$ be the finite-volume Hamiltonian of an interacting Fermi gas in a periodic box, with ground-state energy $E^L$. For momentum ${\bf k}$, let $\epsilon^\pm({\bf k})$ denote…
