DOI: 10.1007/jhep09(2018)166
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.

DOI: 10.1016/j.aop.2017.10.002
Abstract: Abstract We examine the renormalization of the first order formulation of the Yang–Mills theory, by using the BRST identities. These preserve the gauge invariance of the theory and enable a recursive proof of renormalizability to… read more here.
