Time-of-flight of solitary waves in dry and wet chains of beads: experimental results and phenomenological models
R. Labbé, L. Vergara, I. Olivares
A solitary wave is generated by impacting a dry chain of beads on one of its ends. Its speed depends on the speed of the striker and the details of the contact force. The tim…
Model for Dissipative Highly Nonlinear Waves in Dry Granular Systems
Lautaro Vergara
A model is presented for the characterization of dissipative effects on highly nonlinear waves in one-dimensional dry granular media. The model includes three terms: Hertzian, visc…
Delayed Scattering of Solitary Waves from Interfaces in a Granular Container
Lautaro Vergara
In granular media, the characterization of the behavior of solitary waves around interfaces is of importance in order to look for more applications of these systems. We study the b…
(A note on) self-similarity in granular media
Lautaro Vergara
It is shown that the phenomenon of self-similarity appears in granular media, with an intergrain potential , , where is the overlap between the grains…
Convexity of the effective action from functional flows
Daniel F. Litim, Jan M. Pawlowski, Lautaro Vergara
We show that convexity of the effective action follows from its functional flow equation. Our analysis is based on a new, spectral representation. The results are relevant for the…
Corrections to Universal Fluctuations in Correlated Systems: the 2D XY-model
G. Mack, G. Palma, L. Vergara
Generalized universality, as recently proposed, postulates a universal non-Gaussian form of the probability density function (PDF) of certain global observables for a wide class of…
