Holographic Renormalization [PDF]
Nuclear Physics B, 2001 We systematically develop the procedure of holographic renormalization for RG flows dual to asymptotically AdS domain walls. All divergences of the on-shell bulk action can be cancelled by adding covariant local boundary counterterms determined by the ...

Journal of Mathematical Physics, 1996 A careful analysis of differential renormalization shows that a distinguished choice of renormalization constants allows for a mathematically more fundamental interpretation of the scheme.

Introduction to renormalization [PDF]
Condensed Matter Physics, 2006 In these lectures I discuss peculiarities of the critical behaviour of "non-ideal" systems as it is explained by the renormalization group approach. Examples considered here include account of the single-ion anisotropy, structural disorder, frustrations.

Exponential renormalization [PDF]
Annales Henri Poincaré, 2010 Moving beyond the classical additive and multiplicative approaches, we present an "exponential" method for perturbative renormalization. Using Dyson's identity for Green's functions as well as the link between the Faa di Bruno Hopf algebra and the Hopf ...

On the renormalization of Hamiltonians [PDF]
AIP Conference Proceedings, 1999 We introduce a novel method for the renormalization of the Hamiltonian operator in Quantum Field Theory in the spirit of the Wilson renormalization group. By a series of unitary transformations that successively decouples the high-frequency degrees of freedom and partially diagonalizes the high-energy part, we obtain the effective Hamiltonian for the ...

The Problem of Renormalization of Chiral Nuclear Forces
Frontiers in Physics, 2020 Ever since quantum field theory was first applied to the derivation of nuclear forces in the mid-twentieth century, the renormalization of pion exchange with realistic couplings has presented a challenge.

Physical Review D, 2012 We extend our previous study of the vector charmonium states within a renormalization approach with boundary conditions to the full spectrum of charmonium and bottomonium. On the light of the predicted spectrum we comply to assignments suggested in the literature. A comparison with the regularized quark model is also included.

Predominance of non-adiabatic effects in zero-point renormalization of the electronic band gap [PDF]
npj Computational Materials, 2020 Electronic and optical properties of materials are affected by atomic motion through the electron–phonon interaction: not only band gaps change with temperature, but even at absolute zero temperature, zero-point motion causes band-gap renormalization. We

Giant bandgap renormalization and excitonic effects in a monolayer transition metal dichalcogenide semiconductor. [PDF]
Nature Materials, 2014 Two-dimensional (2D) transition metal dichalcogenides (TMDs) are emerging as a new platform for exploring 2D semiconductor physics. Reduced screening in two dimensions results in markedly enhanced electron-electron interactions, which have been predicted
