Entanglement Hamiltonians In Conformal Field Theories | Stanford Institute For Theoretical Physics

Entanglement Hamiltonians In Conformal Field Theories | Stanford Institute For Theoretical Physics Our main assumption (following peschel) is that the green's function determines all subsequent correlators and we can obtain the entanglement hamiltonian from the green's function by computing the appropriate resolvent. We determine the modular hamiltonian of chiral fermions on the torus, for an arbitrary set of disjoint intervals at generic temperature. we find that, in addition to a local unruh like term, each point is nonlocally coupled to an infinite but discrete set of other points, even for a single interval. We determine both analytically and numerically the entanglement between chiral degrees of freedom in the ground state of massive perturbations of 1 1 dimensional conformal field theories quantised on a cylinder. In this letter we study the effect of topological zero modes on entanglement hamiltonians and entropy of chiral fermion systems in 1d, such as the quantum hall edge and the edge of a p ip superconductor.

In this letter we study the effect of topological zero modes on entanglement hamiltonians and entropy of chiral fermion systems in 1d, such as the quantum hall edge and the edge of a p ip superconductor. We show how riemann hilbert solutions combined with nite rank perturbation theory allow us to obtain exact expressions for entanglement hamiltonians. in the absence of the zero mode, the resulting entanglement hamiltonians consists of local and bi local terms. In this letter, we study the effect of topological zero modes on entanglement hamiltonians and the entropy of free chiral fermions in (1 1)d. we show how riemann hilbert solutions combined with finite rank perturbation theory allow us to obtain exact expressions for entanglement hamiltonians. Here we analyze in detail several examples involving excited states of chiral fermions (dirac and majorana) on a spatial circle. we compute the exact entanglement hamiltonians and an exact. 2.1, we compute the entanglement hamiltonian for a basic excited state of chiral dirac fermions where an addi ional particle has been introduced above the dirac sea. we use the same method to compute the change in entropy relative to the entanglement entropy of the dira.
