Critical Exponent for the Lyapunov Exponent and Phase Transitions -- The Generalized Hamiltonian Mean-Field Model
Moisés F. P. Silva, Tarcísio M. Rocha Filho, Yves Elskens
We compute semi-analytic and numerical estimates for the largest Lyapunov exponent in a many-particle system with long-range interactions, extending previous results for the Hamilt…

Constraining spatial variations of the fine-structure constant in symmetron models
A. M. M. Pinho, M. Martinelli, C. J. A. P. Martins
We introduce a methodology to test models with spatial variations of the fine-structure constant , based on the calculation of the angular power spectrum of these measurements.…
