Reply to Valla's Comment on "Multiple Bosonic Mode Coupling in Electron Self-Energy of (La_{2-x}Sr_x)CuO_4"

TL;DR

This paper confirms that the fine structure observed in the electron self-energy of LSCO is intrinsic, supported by improved measurements and simulations, countering previous speculation that it was noise.

Contribution

It demonstrates the intrinsic nature of the fine structure in LSCO's electron self-energy through enhanced measurements and simulations, clarifying prior uncertainties.

Findings

Fine structure in LSCO's electron self-energy is intrinsic.

Improved energy resolution confirms the structure's authenticity.

Simulations support the experimental observations.

Abstract

From consistency among different measurements, new measurements with better energy resolution, as well as simulations, we show that the fine structure we have identified in the electron self-enery of LSCO is intrinsic, not due to random noise as Valla speculated.
