DOI: 10.1002/jcc.70186
Abstract: The in‐medium similarity renormalization group (IMSRG) approach, based on a continuous unitary transformation, has been applied to closed‐shell atoms. The flow equation, which is derived for the Hamiltonian, has been solved along with imaginary‐time or… read more here.

Some remarks on the renormalization group and Chapman‐Enskog type methods in singularly perturbed problems
Sign Up to like & getrecommendations! Published in 2020 at "Mathematical Methods in the Applied Sciences"
DOI: 10.1002/mma.6273
Abstract: In this paper, we show that for a large class of singularly perturbed problems, the classical Chapman‐Enskog asymptotic procedure leads, in a shorter way, to the same asymptotic expansion as the renormalization group (RG) approach.… read more here.

DOI: 10.1007/jhep06(2025)106
Abstract: We calculate two-loop renormalization group equations (RGEs) in the Standard Model Effective Field Theory (SMEFT) with right-handed neutrinos, i.e., the so-called νSMEFT, up to dimension five. Besides the two-loop RGEs of dimension-five (dim-5) operators, we… read more here.

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.

Abstract: Abstract We derive a general formula of the tensor network representation for d-dimensional lattice fermions with ultra-local interactions, including Wilson fermions, staggered fermions, and domain-wall fermions. The Grassmann tensor is concretely defined with auxiliary Grassmann… read more here.
