Phase diagram of a cold polarized Fermi gas
D. T. Son, M. A. Stephanov
We propose a phase diagram for a cold polarized atomic Fermi gas with zero-range interaction. We identify four main phases in the plane of density and polarization: the superfluid…
Viscosity in Strongly Interacting Quantum Field Theories from Black Hole Physics
P. Kovtun, D. T. Son, A. O. Starinets
The ratio of shear viscosity to volume density of entropy can be used to characterize how close a given fluid is to being perfect. Using string theory methods, we show that this ra…
On the equivalence between the Boltzmann equation and classical field theory at large occupation numbers
A. H. Mueller, D. T. Son
We consider a system made up of exictations of a neutral scalar field, ϕ, having a λϕ^4 interaction term. Starting from an ensemble where the occupation number f is large, but λf i…
Classical Preheating and Decoherence
D. T. Son
We establish the equivalence between the quantum evolution of spatially homogeneous oscillations of a scalar field and that of an analogous classical system with certain random ini…
Singular Classical Solutions and Tree Multiparticle Cross Sections in Scalar Theories
F. L. Bezrukov, M. V. Libanov, D. T. Son +1
We consider the features of multiparticle tree cross sections in scalar theories in the framework of a semiclassical approach. These cross sections at large multiplicities have exp…
An Example of Semiclassical Instanton-Like Scattering: (1+1) Dimensional Sigma Model
V. A. Rubakov, D. T. Son, P. G. Tinyakov
A solution to the classical field equations in the massless (1+1)-dimensional O(3) sigma model is found, which describes a multi-particle instanton-like transition at high energy.…
