Abstract: A bstractQuantum Renyi relative entropies provide a one-parameter family of distances between density matrices, which generalizes the relative entropy and the fidelity. We study these measures for renormalization group flows in quantum field theory. We… read more here.

Abstract: We revisit optimization of functional renormalization group flows by analyzing regularized loop integrals. This leads us to a principle, the , and a corresponding order relation which allows us to order existing regularization schemes with… read more here.

Abstract: We present a prescription for using the a central charge to determine the flow of a strongly coupled supersymmetric theory from its weakly coupled dual. The approach is based on the equivalence of the scale-dependent… read more here.

DOI: 10.1103/physrevlett.128.021603
Abstract: We consider line defects in d-dimensional conformal field theories (CFTs). The ambient CFT places nontrivial constraints on renormalization group (RG) flows on such line defects. We show that the flow on line defects is consequently… read more here.
