Theory-based design of sintered granular composites triples three-phase boundary in fuel cells
Shahar Amitai, Antonio Bertei, Raphael Blumenfeld
Solid-oxide fuel cells produce electric current from energy released by a spontaneous electrochemical reaction. The efficiency of these devices depends crucially on the microstruct…
Affine and topological structural entropies in granular statistical mechanics: explicit calculations and equation of state
Shahar Amitai, Raphael Blumenfeld
We identify two orthogonal sources of structural entropy in rattler-free granular systems - affine, involving structural changes that only deform the contact network, and topologic…
Failure of the Volume Function in Granular Statistical Mechanics and an Alternative Formulation
Raphael Blumenfeld, Shahar Amitai, Joe F. Jordan +1
We first show that the currently accepted statistical mechanics for granular matter is flawed. The reason is that it is based on the volume function, which depends only on a minute…
Modifying continuous-time random walks to model finite-size particle diffusion in granular porous media
Shahar Amitai, Raphael Blumenfeld
The continuous-time random walk (CTRW) model is useful for alleviating the computational burden of simulating diffusion in actual media. In principle, isotropic CTRW only requires…
Fine tuning in an A4-based Tri-Bimaximal neutrino-mixing model
Shahar Amitai
The A4 group stands in the basis of many models that predict Tri-Bimaximal neutrino mixing at leading order. We study the Altarelli-Feruglio A4 symmetry model and show that in orde…
Abelian symmetries as the source of the small neutrino-related flavor parameters
Shahar Amitai
There are four neutrino-related flavor parameters that have been measured: The three mixing angles s_{23}, s_{12}, s_{13}, and the ratio of mass-squared differences r_{23}. Of thes…
