Shear Viscosity in the O(N) Model
We compute the shear viscosity in the O(N) model at first nontrivial order in the large N expansion. The calculation is organized using the 1/N expansion of the 2PI effective action (2PI-1/N expansion) to next-to-leading order, which leads to an integral equation summing ladder and bubble diagrams. We also consider the weakly coupled theory for arbitrary N , using the three-loop expansion of th...
متن کاملModel of Shear Viscosity for Underfill Flows
To analyze the flow of an underfill encapsulant between the chip and substrate, a shear viscosity model is needed. This paper presents a model of the viscosity for the flow of slurry between two parallel walls, which is a typical situation found in electronic packaging applications. It is postulated that the flow behavior of a dense slurry is governed by the particle-particle and particle-wall ...
متن کاملUniversality of the shear viscosity in supergravity
Kovtun, Son and Starinets proposed a bound on the shear viscosity of any fluid in terms of its entropy density. We argue that this bound is always saturated for gauge theories at large ’t Hooft coupling, which admit holographically dual supergravity description.

Shear viscosity of a model for confined granular media.
The shear viscosity in the dilute regime of a model for confined granular matter is studied by simulations and kinetic theory. The model consists on projecting into two dimensions the motion of vibrofluidized granular matter in shallow boxes by modifying the collision rule: besides the restitution coefficient that accounts for the energy dissipation, there is a separation velocity that is added...
