Finite-temperature hole dynamics in the t-J model: Exact results for high dimensions
arXiv:cond-mat/9809150 · doi:10.1209/epl/i1998-00341-6
Abstract
We discuss the dynamics of a single hole in the t-J model at finite temperature, in the limit of large spatial dimensions. The problem is shown to yield a simple and physically transparent solution, that exemplifies the continuous thermal evolution of the underlying string picture from the T=0 string-pinned limit through to the paramagnetic phase.
