Coherence revival during the attosecond electronic and nuclear quantum photodynamics of the ozone molecule

TL;DR

This study investigates the ultrafast quantum dynamics of ozone, revealing coherence revival between electronic states and oscillations in nuclear wave packets, with potential experimental observation using attosecond pulses.

Contribution

It demonstrates the coherence revival phenomenon in ozone's electronic states during attosecond photodynamics using advanced quantum simulations.

Findings

Coherence between electronic states reappears after laser pulse

Nuclear wave packets oscillate between chemical bonds

Potential for experimental observation with attosecond pulses

Abstract

A coherent superposition of two electronic states of ozone (ground and Hartley B) is prepared with a UV pump pulse. Using the multiconfiguration time-dependent Hartree approach, we calculate the subsequent time evolution of the two corresponding nuclear wave packets and the coherence between them. The resulting wave packet shows an oscillation between the two chemical bonds. Even more interesting, the coherence between the two electronics states reappears after the laser pulse is switched off, which could be observed experimentally with an attosecond probe pulse.
