Generation of Density Perturbations by Primordial Magnetic Fields

Kavli Affiliate: Robert Rosner | First 5 Authors: Eun-jin Kim, Angela Olinto, Robert Rosner, , | Summary: We study the generation and evolution of density perturbations and peculiar velocities due to primordial magnetic fields. We assume that a random magnetic field was present before recombination and follow the field’s effect on the baryon fluid starting […]

Particle Physics Models, Topological Defects and Electroweak Baryogenesis

Kavli Affiliate: A. C. Davis | First 5 Authors: M. Trodden, A-C. Davis, R. Brandenberger, , | Summary: We demonstrate the viability of electroweak baryogenesis scenarios in which the necessary departure from equilibrium is realized by the evolution of a network of topological defects. We consider several effective models of TeV physics, each addressing a […]

Phi^4 Kinks: Statistical Mechanics

Kavli Affiliate: Salman Habib | First 5 Authors: Salman Habib, , , , | Summary: Some recent investigations of the thermal equilibrium properties of kinks in a $1+1$-dimensional, classical $Φ^4$ field theory are reviewed. The distribution function, kink density, correlation function, and certain thermodynamic quantities were studied both theoretically and via large scale simulations. A […]

Quantum Diffusion

Kavli Affiliate: Salman Habib | First 5 Authors: Salman Habib, , , , | Summary: We consider a simple quantum system subjected to a classical random force. Under certain conditions it is shown that the noise-averaged Wigner function of the system follows an integro-differential stochastic Liouville equation. In the simple case of polynomial noise-couplings this […]
