Quark confinement and the renormalization group [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011 Recent approaches to quark confinement are reviewed, with an emphasis on their connection to renormalization group (RG) methods. Basic concepts related to confinement are introduced: the string tension, Wilson loops and Polyakov lines, string breaking, string tension scaling laws, centre symmetry breaking and the deconfinement transition ...

The One‐Dimensional Coulomb Hamiltonian: Properties of Its Birman–Schwinger Operator
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The objective of the present paper is to study in detail the properties of the Birman–Schwinger operator for a self‐adjoint realization of the one‐dimensional Hamiltonian with the Coulomb potential, both when the Hamiltonian is defined only on ℝ+$$ {\mathbb{R}}_{+} $$ and when it is defined on the whole real line.

On avoiding Ostrogradski instabilities within Asymptotic Safety
Journal of High Energy Physics, 2017 We study the renormalization group flow of gravity coupled to scalar matter using functional renormalization group techniques. The novel feature is the inclusion of higher-derivative terms in the scalar propagator.

Climatic Specific Energy Rating Analysis of Outdoor PV Field Data
Progress in Photovoltaics: Research and Applications, EarlyView.The study evaluates the Climatic Specific Energy Rating (CSER) of Photovoltaic device according to IEC 61853 standard series. It explores the use of long‐term PV outdoor field data in order to understand how the length and seasonality of the data acquisition period affects the reliability of the CSER parameter. It provides important insights for the PV

Particle &Particle Systems Characterization, EarlyView.The atomic arrangement of few‐nm‐wide surfactant‐free noble metal (AuAg) decahedral nanoparticles is characterized using a structural refinement based on Pair Distribution Function (PDF) derived from Precession Electron Diffraction (PED). The results indicate that the measured structure is not well described by the classical Bagley body‐centered ...
