Amplitude ratios in ρ0 leptoproductions and GPDs [PDF]
EPJ Web of Conferences, 2017 We investigate exclusive leptoproduction of ρ0 meson. These reactions were analyzed within the factorizing handbag approach. In our model good agreement of observables for light meson production with experimental data in a wide energy range was found ...

Susceptibility Amplitude Ratios Near a Lifshitz Point [PDF]
Physical Review B, 1999 The susceptibility amplitude ratio in the neighborhood of a uniaxial Lifshitz point is calculated at one-loop level using field-theoretic and $\epsilon_{L}$-expansion methods.

Amplitude Ratios and Neural Network Quantum States [PDF]
Quantum, 2023 Neural Network Quantum States (NQS) represent quantum wavefunctions by artificial neural networks. Here we study the wavefunction access provided by NQS defined in [Science, 355, 6325, pp.

Universal Amplitude Ratios for Constrained Critical Systems [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2014 The critical properties of systems under constraint differ from their ideal counterparts through Fisher renormalization. The mathematical properties of Fisher renormalization applied to critical exponents are well known: the renormalized indices obey the

Three-loop critical exponents, amplitude functions, and amplitude ratios from variational perturbation theory [PDF]
Physical Review E, 2000 We use variational perturbation theory to calculate various universal amplitude ratios above and below T_c in minimally subtracted phi^4-theory with N components in three dimensions.

A new class of short distance universal amplitude ratios [PDF]
Journal of Physics A: Mathematical and General, 2003 We propose a new class of universal amplitude ratios which involve the first terms of the short distance expansion of the correlators of a statistical model in the vicinity of a critical point.

Specific heat amplitude ratios for anisotropic Lifshitz critical behaviors [PDF]
Physical Review B, 2003 We determine the specific heat amplitude ratio near a $m$-axial Lifshitz point and show its universal character. Using a recent renormalization group picture along with new field-theoretical $\epsilon_{L}$-expansion techniques, we established this ...

Ising model with mixed boundary conditions: universal amplitude ratios [PDF]
Nuclear Physics B, 2009 In the vicinity of boundaries the bulk universality class of critical phenomena splits into several boundary universality classes, depending upon whether the tendency to order in the boundary is smaller or larger than in the bulk.

Scaling functions and amplitude ratios for the Potts model on an uncorrelated scale-free network [PDF]
Condensed Matter Physics, 2014 We study the critical behaviour of the q-state Potts model on an uncorrelated scale-free network having a power-law node degree distribution with a decay exponent λ.

Universal amplitude ratios in the 2D four state Potts model [PDF]
Nuclear Physics B, 1999 We present a Monte Carlo study of various universal amplitude ratios of the two dimensional q=4 Potts model. We simulated the model close to criticality in both phases taking care to keep the systematic errors, due to finite size effects and logarithmic ...
