Linear response of entanglement entropy to T T ¯ $$ T\overline{T} $$ in massive QFTs
Journal of High Energy Physics, 2023 We compute the leading correction to entanglement entropy in T T ¯ $$ T\overline{T} $$ deformed massive QFTs. We show that both for massive scalar and Dirac fermion, the leading order correction to the entanglement entropy of half space comes from the ...

The fractional Lipschitz caloric capacity of Cantor sets
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract We characterize the s$s$‐parabolic Lipschitz caloric capacity of corner‐like s$s$‐parabolic Cantor sets in Rn+1$\mathbb {R}^{n+1}$ for 1/2

Advanced Photonics Research, Volume 7, Issue 2, February 2026.This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

A Clarification on Quantum‐Metric‐Induced Nonlinear Transport
Advanced Science, Volume 13, Issue 7, 3 February 2026.How does the quantum metric truly govern the nonlinear transport? The longstanding theoretical discrepancies are resolved in quantum‐metric‐induced nonlinear transport and the correct intrinsic nonlinear conductivity is identified. Furthermore, a toy model is engineered to suppress the competing effects, uniquely highlighting the role of quantum metric

Regularization and renormalization of semiclassical QCD
Nuclear Physics B, 1979 We continue our discussion of how to consistently approximate QCD by expanding around the multi-instanton set of classical field configurations. Noting the divergences of the diagrammatic expansions in g and in the instanton density, we introduce Pauli-Villars regulators to render the theory finite. This is not manifestly gauge invariant and we discuss

Renormalization: a quasi-shuffle approach
, 2018 In recent years, the usual BPHZ algorithm for renormalization in perturbative quantum field theory has been interpreted, after dimensional regularization, as a Birkhoff decomposition of characters on the Hopf algebra of Feynman graphs, with values in a ...

On the Modeling of Irreversibility by Relaxator Liouville Dynamics
Annalen der Physik, Volume 538, Issue 2, February 2026.A general approach to modeling irreversibility starting from microscopic reversibility is presented. A relaxator that breaks reversibility condenses in the Liouville operator of the relevant degrees of freedom. The irreversible relaxator Liouville equation contains memory effects and initial correlations of all degrees of freedom. Stationary states are

Notes on Feynman Integrals and Renormalization [PDF]
, 2010 I review various aspects of Feynman integrals, regularization and renormalization. Following Bloch, I focus on a linear algebraic approach to the Feynman rules, and I try to bring together several renormalization methods found in the literature from a ...
