Bonding situations in tricoordinated beryllium phenyl complexes
Journal of Computational Chemistry, Volume 44, Issue 3, Page 397-405, January 30, 2023., 2023 The bonding situation in tricoordinated beryllium phenyl complexes was evaluated. In all compounds π‐delocalisation was present in all compounds even though the beryllium‐element bonds are highly polarized. This delocalisation accounts for the rather small contribution of π‐interactions to the overall orbital energies of these compounds.

Renormalization Group in Non-Relativistic Quantum Statistics [PDF]
EPJ Web of Conferences, 2020 Dynamic behaviour of a boson gas near the condensation transition in the symmetric phase is analyzed with the use of an effective large-scale model derived from time-dependent Green functions at finite temperature.

Novel demonstration of the renormalization group invariance of the fixed-order predictions using the principle of maximum conformality and the C -scheme coupling [PDF]
Physical Review D, 2018 As a basic requirement of the renormalization group invariance, any physical observable must be independent of the choice of both the renormalization scheme and the initial renormalization scale.

Redox‐active ligands as a challenge for electronic structure methods
Journal of Computational Chemistry, Volume 44, Issue 3, Page 468-479, January 30, 2023., 2023 The 3d transition metal complexes with redox‐active ligands are highly attractive for catalysis, but a challenge for first‐principles electronic structure methods such as density functional theory (DFT). The ligands’ redox‐activity can lead to the self‐consistent field algorithm converging to high‐energy solutions.

Mutual information, neural networks and the renormalization group [PDF]
Nature Physics, 2017 Physical systems differing in their microscopic details often display strikingly similar behaviour when probed at macroscopic scales. Those universal properties, largely determining their physical characteristics, are revealed by the powerful ...

B physics beyond the Standard Model at one loop: complete renormalization group evolution below the electroweak scale [PDF]
Journal of High Energy Physics, 2017 General analyses of B-physics processes beyond the Standard Model require accounting for operator mixing in the renormalization-group evolution from the matching scale down to the typical scale of B physics.

Differential Renormalization, the Action Principle and Renormalization Group Calculations [PDF]
Z.Phys. C67 (1995) 531-541, 1994 General prescriptions of differential renormalization are presented. It is shown that renormalization group functions are straightforwardly expressed through some constants that naturally arise within this approach. The status of the action principle in the framework of differential renormalization is discussed.

Renormalization Group evolution from on-shell SMEFT
Journal of High Energy Physics, 2021 We describe the on-shell method to derive the Renormalization Group (RG) evolution of Wilson coefficients of high dimensional operators at one loop, which is a necessary part in the on-shell construction of the Standard Model Effective Field Theory ...

Gradient flow and the renormalization group [PDF]
Progress of Theoretical and Experimental Physics, 2018 We investigate the renormalization group (RG) structure of the gradient flow. Instead of using the original bare action to generate the flow, we propose to use the effective action at each flow time.
