Abstract:
We study the ground-state entanglement Hamiltonian for an interval of N sites
in a free-fermion chain with arbitrary filling. By relating it to a commuting
operator, we find explicit expressions for its matrix elements in the large-N
limit. The results agree with numerical calculations and show that deviations
from the conformal prediction persist even for large systems.
