A bstract We study the continuum limit of the entanglement Hamiltonian of a sphere for the
massless scalar field in its ground state by employing the lattice model defined through the …

We consider free-fermion chains in the ground state and the entanglement Hamiltonian for a
subsystem consisting of two separated intervals. In this case, one has a peculiar long-range …

We present a numerical approximation scheme for the Tomita–Takesaki modular operator of
local subalgebras in linear quantum fields, working at one-particle level. This is applied to …

The thermodynamics of local causal horizons has been shown to imply gravitational
dynamics. In this essay, we discuss the principles underlying this observation, and its …

We study the modular Hamiltonian associated with a Gaussian state on the Weyl algebra.
We obtain necessary/sufficient criteria for the local equivalence of Gaussian states …

In this work we study the nature of correlations among mixed states in the setup of two
symmetric strips. We use various tools to determine how the bulk geometry could be …

Based on the construction provided in our paper “Covariant homogeneous nets of standard
subspaces”, Comm Math Phys 386: 305–358,(2021), we construct non-modular covariant …

It is well-known that entanglement entropy in field theory at its ground state is dominated by
an area law term, presenting a similarity to the entropy of black holes. It is interesting to …

Nesta tese, estudamos a temperatura de uma região abstrata do espaco-tempo chamada
cone duplo, que também é chamado de diamante. A estrutura sob consideração é a teoria …
