Multireference Perturbation Theory with Cholesky Decomposition for the Density Matrix Renormalization Group. [PDF]
J Chem Theory Comput, 2017 We present a second-order N-electron valence state perturbation theory (NEVPT2) based on a density matrix renormalization group (DMRG) reference wave function that exploits a Cholesky decomposition of the two-electron repulsion integrals (CD-DMRG-NEVPT2).

Nuclear Physics B, 2017 We compare the subtractive renormalization and the Wilsonian renormalization group approaches in the context of an effective field theory for the two-nucleon system. Based on an exactly solvable model of contact interactions, we observe that the standard

Laplacian renormalization group for heterogeneous networks [PDF]
Nature Physics, 2022 The renormalization group method is routinely employed in studies of criticality in many areas of physics. A framework based on a field theoretical description of information diffusion now extends this tool to the study of complex networks.

Renormalization group flow as optimal transport [PDF]
Physical Review D, 2022 We establish that Polchinski's equation for exact renormalization group flow is equivalent to the optimal transport gradient flow of a field-theoretic relative entropy.

Renormalization Group Flows on Line Defects. [PDF]
Physical Review Letters, 2021 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.

Interpolation Formulas for Asymptotically Safe Cosmology
Universe, 2023 Simple interpolation formulas are proposed for the description of the renormalization group (RG) scale dependences of the gravitational couplings in the framework of the 2-parameters Einstein-Hilbert (EH) theory of gravity and applied to a simple ...

Multi-collinear splitting kernels for track function evolution
Journal of High Energy Physics, 2023 Jets and their substructure play a central role in many analyses at the Large Hadron Collider (LHC). To improve the precision of measurements, as well as to enable measurement of jet substructure at increasingly small angular scales, tracking information

Triad second renormalization group
Journal of High Energy Physics, 2022 We propose a second renormalization group (SRG) in the triad representation of tensor networks. The SRG method improves two parts of the triad tensor renormalization group, which are the decomposition of intermediate tensors and the preparation of ...

ON SPECTRAL RENORMALIZATION GROUP [PDF]
Reviews in Mathematical Physics, 2009 The operator-theoretic renormalization group (RG) methods are powerful analytic tools to explore spectral properties of field-theoretical models such as quantum electrodynamics (QED) with non-relativistic matter. In this paper, these methods are extended and simplified.
