Correlation between slip precursors and topological length scales at the onset of frictional sliding
Gianluca Costagliola, Federico Bosia, Nicola M. Pugno
Understanding the interplay between concurrent length scales is a fundamental issue in many problems involving friction between sliding interfaces, from tribology to the study of e…
Experimental and numerical study of the effect of surface patterning on the frictional properties of polymer surfaces
Simone Balestra, Gianluca Costagliola, Amedeo Pegoraro +6
We describe benchmark experiments to evaluate the frictional properties of laser patterned low-density polyethylene as a function of sliding velocity, normal force and humidity. Th…
Energy trapped Ising model
Andrea Amoretti, Gianluca Costagliola, Nicodemo Magnoli +1
In this paper we have considered the 3D Ising model perturbed with the energy operator coupled with a non uniform harmonic potential acting as a trap, showing that this system sati…
A 2-D Model for friction of complex anisotropic surfaces
Gianluca Costagliola, Federico Bosia, Nicola M. Pugno
The friction force observed at macroscale is the result of interactions at various lower length scales that are difficult to model in a combined manner. For this reason, simplified…
Tuning friction with composite hierarchical surfaces
Gianluca Costagliola, Federico Bosia, Nicola M. Pugno
Macroscopic friction coefficients observed in experiments are the result of various types of complex multiscale interactions between sliding surfaces. Therefore, there are several…
Applications of Jarzynski's relation in lattice gauge theories
Alessandro Nada, Michele Caselle, Gianluca Costagliola +2
Jarzynski's equality is a well-known result in statistical mechanics, relating free-energy differences between equilibrium ensembles with fluctuations in the work performed during…
Static and dynamic friction of hierarchical surfaces
Gianluca Costagliola, Federico Bosia, Nicola M. Pugno
Hierarchical structures are very common in Nature, but only recently have they been systematically studied in materials physics, in order to understand the specific effects they ca…
Conformal perturbation of off-critical correlators in the 3D Ising universality class
Michele Caselle, Gianluca Costagliola, Nicodemo Magnoli
Thanks to the impressive progress of conformal bootstrap methods we have now very precise estimates of both scaling dimensions and OPE coefficients for several 3D universality clas…
Jarzynski's theorem for lattice gauge theory
Michele Caselle, Gianluca Costagliola, Alessandro Nada +2
Jarzynski's theorem is a well-known equality in statistical mechanics, which relates fluctuations in the work performed during a non-equilibrium transformation of a system, to the…
OPE Coefficients of the 3D Ising model with a trapping potential
Gianluca Costagliola
Recently the OPE coefficients of the 3D Ising model universality class have been calculated by studying the two-point functions perturbed from the critical point with a relevant fi…
Numerical determination of OPE coefficients in the 3D Ising model from off-critical correlators
M. Caselle, G. Costagliola, N. Magnoli
We propose a general method for the numerical evaluation of OPE coefficients in three dimensional Conformal Field Theories based on the study of the conformal perturbation of two p…
An analytical continuation approach for evaluating emission lineshapes of molecular aggregates and the adequacy of multichromophoric Förster theory
Leonardo Banchi, Gianluca Costagliola, Akihito Ishizaki +1
In large photosynthetic chromophore-protein complexes not all chromophores are coupled strongly, and thus the situation is well described by formation of delocalized states in cert…
Critical dynamics in trapped particle systems
Gianluca Costagliola, Ettore Vicari
We discuss the effects of a trapping space-dependent potential on the critical dynamics of lattice gas models. Scaling arguments provide a dynamic trap-size scaling framework to de…
