Quantum gravity from the point of view of locally covariant quantum field theory

Quantum gravity from the point of view of locally covariant quantum field theory

... The algebra generated by the relative observables is subsequently quantized with the use of the BV formalism. For the purposes of perturbation theory we replace the diffeomorphism group by the Lie algebra of vector ...

Probabilities and signalling in quantum field theory

Probabilities and signalling in quantum field theory

... We present an approach to computing probabilities in quantum field theory for a wide class of source–detector models. The approach works directly with probabilities and not with squared matrix elements, and ...

Quantum spectral curve as a tool for a perturbative quantum field theory

... Instead of computing corrections in wrappings, the thermodynamic Bethe Ansatz (TBA) ap- proach [34] was adapted to the AdS/CFT case and the TBA equations which are expected to be exact at any λ were derived [35–38]. ...
