The two mode Heaviside equation for ultra-short laser pulses interaction with matter

TL;DR

This paper introduces a two-mode Heaviside equation to model ultra-short laser pulse interactions with matter, revealing simultaneous excitation of electrons and phonons that diffuse with finite velocities.

Contribution

The paper formulates and solves a novel two-mode Heaviside equation capturing the coupled dynamics of electrons and phonons during ultra-short laser pulse interactions.

Findings

Electrons and phonons are excited simultaneously.

Both species diffuse with finite velocities.

The model provides insights into ultra-short laser-matter interactions.

Abstract

In his paper the two mode Heaviside equation was formulated and solved. It was shown that the interaction of ultra-short laser pulses with matter leads to two mode excitation electrons and phonons which afterwards diffuse with finite velocities.
