Heatons induced by attosecond laser pulses

TL;DR

This paper investigates how attosecond laser pulses interact with matter, demonstrating that heatons, or thermal wave packets, can be modeled as nondispersive entities using a modified Klein-Gordon equation, with damping over time.

Contribution

It introduces a modified Klein-Gordon equation to describe heaton propagation, revealing their nondispersive nature under attosecond pulse excitation.

Findings

Heatons are nondispersive thermal wave packets under attosecond pulses.

Heatons are damped over time with a relaxation-time-scale damping factor.

The modified Klein-Gordon equation effectively models heaton dynamics.

Abstract

In this paper the dynamics of the interaction of attosecond laser pulses with matter is investigated. It will be shown that the master equation: modified Klein-Gordon equation describes the propagation of the heatons. Heatons are the thermal wave packets. When the duration of the laser pulses is of the order of attosecond the heaton thermal wave packets are nondispersive objects. For infinite time the heatons are damped with damping factor of the order of relaxation time for thermal processes.
