Scrambling-Enhanced Quantum Battery Charging in Black Hole Analogues. [PDF]

Adv Sci (Weinh)
By employing a black‐hole‐analog quantum battery constructed from a position‐dependent XY model, its dynamical behavior is investigated through a quench of the scrambling parameter. It is systematically quantified that how the simulated scrambling improves key performance metrics‐namely, stored energy, peak power, and charging time‐thereby offering a ...

Five-loop anomalous dimensions of ϕ Q operators in a scalar theory with O(N) symmetry

Journal of High Energy Physics, 2022
We compute the complete Q-dependence of anomalous dimensions of traceless symmetric tensor operator ϕ Q in O(N) scalar theory to five-loop. The renormalization factors are extracted from ϕ Q → Q ϕ form factors, and the integrand of form factors are ...

Regularization and renormalization of gauge fields [PDF]

Nuclear Physics B, 1972
A new regularization and renormalization procedure is presented. It is particularly well suited for the treatment of gauge theories. The method works for theories that were known to be renormalizable as well as for Yang-Mills type theories. Overlapping divergencies are disentangled.

Three loop renormalization of the SU(N_c) non-abelian Thirring model [PDF]

, 1999
We renormalize to three loops a version of the Thirring model where the fermion fields not only lie in the fundamental representation of a non-abelian colour group SU(N_c) but also depend on the number of flavours, N_f.

Dimensional regularization and renormalization of QED [PDF]

Communications in Mathematical Physics, 1990
The tree expansion method of renormalization [see e.g. \textit{G. Gallavotti}, Rev. Mod. Phys. 57, 471-562 (1985)] has been applied to QED by \textit{J. Feldman}, \textit{T. Hurd}, and the authors [QED: A proof of renormalizability. Lect. Notes Phys. 312 (1988)]. The purpose of the present paper is to replace the loop regularization used there, with an

Pairing renormalization and regularization within the local density approximation [PDF]

, 2006
We discuss methods used in mean-field theories to treat pairing correlations within the local density approximation. Pairing renormalization and regularization procedures are compared in spherical and deformed nuclei.

Dimensional regularization vs methods in fixed dimension with and without γ 5

Journal of High Energy Physics, 2018
We study the Lorentz and Dirac algebra, including the antisymmetric ϵ tensor and the γ 5 matrix, in implicit gauge-invariant regularization/renormalization methods defined in fixed integer dimensions.

General scalar renormalisation group equations at three-loop order

Journal of High Energy Physics, 2020
For arbitrary scalar QFTs in four dimensions, renormalisation group equations of quartic and cubic interactions, mass terms, as well as field anomalous dimensions are computed at three-loop order in the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme. Utilising

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

Two-loop effective potential for a general renormalizable theory and softly broken supersymmetry [PDF]

, 2001
I compute the two-loop effective potential in the Landau gauge for a general renormalizable field theory in four dimensions. Results are presented for the \bar{MS} renormalization scheme based on dimensional regularization, and for the \bar{DR} and \bar ...
