Effect of Rabi dynamics in resonant x-ray scattering of intense attosecond pulses

TL;DR

This paper theoretically investigates how Rabi oscillations influence resonant x-ray scattering in neon ions when driven by intense attosecond pulses, revealing potential for high-resolution imaging.

Contribution

It introduces a theoretical framework for understanding Rabi dynamics in resonant x-ray scattering with attosecond pulses, highlighting their impact on photon yield and interference effects.

Findings

Photon yield depends on pulse area with an upper bound at high intensities.

Attosecond pulses can produce resonant scattering yields an order of magnitude higher than off-resonance.

Interference effects are influenced by pulse area and initial state, affecting scattering channels.

Abstract

We theoretically study the effects of Rabi oscillations on resonant x-ray scattering in Ne$^+$ using intense attosecond and few-femtosecond pulses. The total photon yield strongly depends on the pulse area and has an upper bound at high intensities. Resonant scattering yields with attosecond pulses can be an order of magnitude higher than those far from resonances. Interference between resonant fluorescence and elastic scattering channels depends on the pulse area and initial state. Our results suggest that resonant x-ray scattering can be exploited for high-resolution, site-specific imaging.
