Abstract: Much has been learned about entanglement due to conformal symmetry and the Rindler properties of the vacuum. In order to go beyond, we propose to use the method of images in QFT. We focus on the solvable yet non-trivial example of the 2d free fermion. After rederiving known results, we obtain the entanglement (modular) Hamiltonian on the torus, which provides the first example of a geometric flow not obtainable from Rindler space. We also comment on its applications to bulk reconstruction in higher spin holography.
