The problem of describing the quantum behavior of gravity, and thus understanding
quantum spacetime, is still open. Loop quantum gravity is a well-developed approach to this …

Using the earlier developed classical Hamiltonian framework as the point of departure, we
carry out a non-perturbative quantization of the sector of general relativity, coupled to matter …

The vacuum entanglement entropy of Maxwell theory, when evaluated by standard methods,
contains an unexpected term with no known statistical interpretation. We resolve this two …

We study the dynamics of quantum correlations in a class of exactly solvable Ising-type
models. We analyze in particular the time evolution of initial Bell states created in a fully …

A bstract In this work we propose a simple and systematic framework for including edge
modes in gauge theories on manifolds with boundaries. We argue that this is necessary in …

In this letter we demonstrate, in an elementary manner, that given a partition of the single
particle Hilbert space into orthogonal subspaces, a Fermi sea may be factored into pairs of …

I review the present theoretical attempts to understand the quantum properties of spacetime.
In particular, I illustrate the main achievements and the main difficulties in: string theory, loop …

It is well-known that quantum groups are relevant to describe the quantum regime of 3d
gravity. They encode a deformation of the gauge symmetries parametrized by the value of …

A bstract We use the asymptotic data at conformal null-infinity to formulate Weinberg's soft-
photon theorem for Abelian gauge theories with massless charged particles. We show that …

The entanglement entropy (EE) of gauge theories in three spacetime dimensions is
analyzed using manifestly gauge-invariant variables defined directly in the continuum …
