Wilsonian Renormalization as a Quantum Channel and the Separability of Fixed Points
Matheus H. Martins Costa, Jeroen van den Brink, Flavio S. Nogueira +1
We show that the Wilsonian formulation of the renormalization group (RG) defines a quantum channel acting on the momentum-space density matrices of a quantum field theory. This inf…

Momentum Space Entanglement from the Wilsonian Effective Action
Matheus H. Martins Costa, Jeroen van den Brink, Flavio S. Nogueira +1
The entanglement between momentum modes of a quantum field theory at different scales is not as well studied as its counterpart in real space, despite the natural connection with t…
