The classical sphaleron transition rate exists and is equal to $1.1 (α_{w} T)^{4}$

J. Ambjørn, A. Krasnitz

Results of a large scale numerical simulation show that the high temperature Chern-Simons number diffusion rate in the electroweak theory has a classical limit $Γ = κ (α_{w} T)^{4}$ , whe…

Scaling in four dimensional quantum gravity

Jan Ambjorn, Jerzy Jurkiewicz

We discuss scaling relations in four dimensional simplicial quantum gravity. Using numerical results obtained with a new algorithm called ``baby universe surgery'' we study the cri…
