Description
Real-space entanglement encodes key information about topological order in many-body systems. Our work aims to target quantum Hall systems, focusing on the entanglement Hamiltonian (EH), which gives the total characterization of entanglement between a subsystem and its environment. In particular, we study the EH for the integer quantum Hall system and show that, for each angular momentum sector, it can be accurately described by a deformation of the physical Hamiltonian with position-dependent prefactors. We demonstrate how this ansatz can provide an approximation of the entanglement entropy and also test the limits at which it fails to do so. Our results provide novel insight into the entanglement properties of gapped two-dimensional electron systems.
