High precision renormalization of the flavour non-singlet Noether currents in lattice QCD with Wilson quarks [PDF]
The European Physical Journal C, 2018 We determine the non-perturbatively renormalized axial current for $$\hbox {O}(a)$$O(a) improved lattice QCD with Wilson quarks. Our strategy is based on the chirally rotated Schrödinger functional and can be generalized to other finite (ratios of ...

Vacuum Polarization in a Zero-Width Potential: Self-Adjoint Extension
Universe, 2021 The effects of vacuum polarization associated with a massless scalar field near pointlike source with a zero-range potential in three spatial dimensions are analyzed.

A Generic Renormalization Method in Curved Spaces and at Finite Temperature
, 1994 Based only on simple principles of renormalization in coordinate space, we derive closed renormalized amplitudes and renormalization group constants at 1- and 2-loop orders for scalar field theories in general backgrounds.

Some Computations of Partition Functions and Tachyon Potentials in Background Independent Off-Shell String Theory [PDF]
, 2000 We discuss what information can be safely extracted from background independent off-shell string theory. The major obstacle in doing so is that renormalization conditions of the underlying world-sheet theories are not exactly known.

Rays to renormalizations [PDF]
Bulletin of the Polish Academy of Sciences Mathematics, 2020 Let P be a non-linear polynomial, K_P the filled Julia set of P, f a renormalization of P and K_f the filled Julia set of f. We show, loosely speaking, that there is a finite-to-one function from the set of P-external rays having limit points in K_f onto the set of f-external rays to K_f such that R and (R) share the same limit set.

Renormalization of Galilean electrodynamics [PDF]
Journal of High Energy Physics, 2020 AbstractWe study the quantum properties of a Galilean-invariant abelian gauge theory coupled to a Schrödinger scalar in 2+1 dimensions. At the classical level, the theory with minimal coupling is obtained from a null-reduction of relativistic Maxwell theory coupled to a complex scalar field in 3+1 dimensions and is closely related to the Galilean ...

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films
Advanced Functional Materials, EarlyView.The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

Quantum Fields and the Cosmological Constant
UniverseIt has been shown that if one solves self-consistently the semiclassical Einstein equations in the presence of a quantum scalar field, with a cutoff on the number of modes, spacetime become flatter when the cutoff increases. Here, we extend the result to

Mathematics, 2019 This work is on the nature and properties of graphs which arise in the study of centered polygonal lacunary functions. Such graphs carry both graph-theoretic properties and properties related to the so-called p-sequences found in the study of centered ...
