Reduction of the proton radius discrepancy by 3σ
Physics Letters B, 2014 We show that in previous analyses of electron–proton scattering, the uncertainties in the statistical procedure to extract the proton charge radius are underestimated. Using a fit function based on a conformal mapping, we can describe the scattering data

Quantum gravity corrections to the Schwarzschild mass [PDF]
, 1999 Vacuum spherically symmetric Einstein gravity in $N\ge 4$ dimensions can be cast in a two-dimensional conformal nonlinear sigma model form by first integrating on the $(N-2)$-dimensional (hyper)sphere and then performing a canonical transformation.

Study of thermodynamical geometries of conformal gravity black hole
European Physical Journal C: Particles and Fields, 2022 This work deals with the applications of thermodynamical geometries on conformal gravity black holes (CGBH) consisting of conformal parameters a and k. The stability of black hole (BH) addressed with the aid of small, middle, large and divergency roots ...

Light Cone Thermodynamics [PDF]
, 2018 We show that null surfaces defined by the outgoing and infalling wave fronts emanating from and arriving at a sphere in Minkowski spacetime have thermodynamical properties that are in strict formal correspondence with those of black hole horizons in ...

An Efficient Method for Estimating the Hydrodynamic Radius of Disordered Protein Conformations [PDF]
Biophysical Journal, 2017 Intrinsically disordered proteins play important roles throughout biology, yet our understanding of the relationship between their sequences, structural properties, and functions remains incomplete. The dynamic nature of these proteins, however, makes them difficult to characterize structurally.

Exceptional boundary states at c=1 [PDF]
, 2001 We consider the CFT of a free boson compactified on a circle, such that the compactification radius $R$ is an irrational multiple of $R_{selfdual}$. Apart from the standard Dirichlet and Neumann boundary states, Friedan suggested [1] that an additional 1-

Energy Momentum Tensor and Marginal Deformations in Open String Field Theory [PDF]
, 2004 Marginal boundary deformations in a two dimensional conformal field theory correspond to a family of classical solutions of the equations of motion of open string field theory.

Computing, Analyzing, and Comparing the Radius of Gyration and Hydrodynamic Radius in Conformational Ensembles of Intrinsically Disordered Proteins [PDF]
, 2019 AbstractThe level of compaction of an intrinsically disordered protein may affect both its physical and biological properties, and can be probed via different types of biophysical experiments. Small-angle X-ray scattering (SAXS) probe the radius of gyration (Rg) whereas pulsed-field-gradient nuclear magnetic resonance (NMR) diffusion, fluorescence ...

Effect of electric charge on conformal compact stars
European Physical Journal C: Particles and Fields, 2019 We investigate the effect of electric charge in anisotropic compact stars with conformal symmetry. We assume that the pressure and the density of the matter inside the stellar structure are large with strong gravitational fields.

Gravitational wave memory in conformally flat spacetimes
Journal of High Energy Physics, 2023 We study the gravitational wave memory effect in spacetimes related to flat space by a conformal transformation. The discussion is general but the gravitational wave length scale is assumed to be small compared with the background curvature radius.
