# Modular conjugation for multicomponent regions

@inproceedings{Abate2022ModularCF, title={Modular conjugation for multicomponent regions}, author={Nicolas Abate and David Blanco and M Z Koĭfman and Guillem P'erez-Nadal}, year={2022} }

We consider a massless Dirac ﬁeld in 1 + 1 dimensions, and compute the Tomita-Takesaki modular conjugation corresponding to the vacuum state and a generic multicomponent spacetime region. We do it by analytic continuation from the modular ﬂow, which was computed recently. We use our result to discuss the validity of Haag duality in this model.

Modular flow is a symmetry of the algebra of observables associated to space-time regions. Being closely related to entanglement, it has played a key role in recent connections between information…

The modular Hamiltonian of chiral fermions on the torus is determined, finding 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 find the density matrix corresponding to the vacuum state of a massless Dirac field in two dimensions reduced to a region of the space formed by several disjoint intervals. We calculate explicitly…

We enumerate the cases in 2d conformal field theory where the logarithm of the reduced density matrix (the entanglement or modular Hamiltonian) may be written as an integral over the energy-momentum…
