A subtheory of a quantum field theory specifies von Neumann subalgebras (the
'observables' in the space-time region) of the von Neumann algebras (the'field'localized in) …

In this paper we use the AdS/CFT correspondence to refine and then establish a set of old
conjectures about symmetries in quantum gravity. We first show that any global symmetry …

In the book of Haag [Local Quantum Physics (Springer Verlag, Berlin, 1992)] about local
quantum field theory the main results are obtained by the older methods of C*-and W …

In holographic duality an eternal Anti-de Sitter black hole is described by two copies of the
boundary Conformal Field Theory in the thermal field double state. In this paper we provide …

A bstract In AdS/CFT we consider a class of bulk geometric quantities inside the
entanglement wedge called reflected minimal surfaces. The areas of these surfaces are dual …

A new approach to the model-independent description of quantum field theories will be
introduced in the present work. The main feature of this new approach is to incorporate in a …

The trace over the degrees of freedom located in a subset of the space transforms the
vacuum state into a mixed density matrix with nonzero entropy. This is usually called …

A bstract We show that generalized symmetries cannot be charged under a continuous
global symmetry having a Noether current. Further, only non-compact generalized …

We develop an operational framework, combining relativistic quantum measurement theory
with quantum reference frames (QRFs), in which local measurements of a quantum field on …

Algebraic quantum field theory provides a general, mathematically precise description of the
structure of quantum field theories, and then draws out consequences of this structure by …
