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…
D-dimensional three-body bound-state problem with zero range interactions
D. S. Rosa, T. Frederico, G Krein +1
We solved analytically the three-body mass-imbalanced problem embedded in D dimensions for zero-range resonantly interacting particles. We derived the negative energy eigenstates o…
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…
Restoration of a Spontaneously Broken Symmetry in an Euclidean Quantum model with Quenched Disorder
G. O. Heymans, N. F. Svaiter, G. Krein
We investigate the low temperature behavior of a system in a spontaneously broken symmetry phase described by an Euclidean quantum model with quenched disorder. Usin…
