AN ANALYTIC STUDY ON THE TWO-TEMPERATURE MODEL FOR ELECTRON-LATTICE THERMAL DYNAMIC PROCESS

ABSTRACT
In this paper, we study the TTM arising in electron-lattice thermal dynamic process by two methods. A new exact traveling solution and variable separation solutions are obtained. They can help us to understand morphological differences in femtosecond laser inducing periodic surface structures on noble metals. Our study examines the role of two competing ultrafast processes following femtosecond laser heating of metals thoroughly. The calculation results confirm the previous experimental work, which is the electron-phonon coupling strength plays a dominant role in the process.
