Infrared behaviour and renormalization scheme invariance of QCD observables [PDF]
, 2006 In this thesis we study the infrared (IR) behaviour of QCD observables, and solutions to the problem of renormalization scheme dependence. We investigate the IR behaviour of all-orders leading-b renormalon resummations for certain Euclidean observables ...

Controllable Superconductivity in Suspended NbSe2
Advanced Electronic Materials, EarlyView.Suspended NbSe2${\rm NbSe}_2$ provides two complementary routes for controlling superconducting transport. Gate‐driven deformation strains the suspended crystal and tunes its critical temperature and current. Weak thermal anchoring enhances thermal feedback, contributing to multistep hysteresis and negative differential resistance.

Gradient flows and the curvature of theory space
Journal of High Energy PhysicsThe metric and potential associated with the gradient property of renormalisation group flow in multiscalar models in d = 4 − ε dimensions are studied. The metric is identified with the Zamolodchikov metric of nearly marginal operators on the sphere.

Renormalization scheme dependence and renormalization group summation [PDF]
, 2017 We consider logarithmic contributions to the free energy, instanton effective action and Laplace sum rules in QCD that are a consequence of radiative corrections.

Perspective: Quantum Computing on Magnetic Racetrack
Advanced Electronic Materials, EarlyView.Magnetic domain walls emerge as mobile qubits on quantum racetracks, where chirality encodes quantum information and current‐driven motion enables flying‐qubit functionality. This Perspective outlines the physical principles, gate mechanisms, material requirements, and experimental roadmap for realizing scalable quantum computing with magnetic textures,

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

Renormalization group for the XYZ model
, 1998 We study in a rigorous way the XYZ spin model by Renormalization Group methods. pacs 75.10.Jm Renormalization Group, Correlations, XYZ chain The XY Z model is exactly solvable [1] by the transfer matrix formalism as it is equivalent [2] to the eight ...

Low-energy theorem revisited and OPE in massless QCD
Journal of High Energy PhysicsWe revisit a low-energy theorem (LET) of NSVZ type in SU(N) QCD with N f massless quarks derived in [1] by implementing it in dimensional regularization. The LET relates n-point correlators in the l.h.s.
