Abstract

A typographical error in an equation in our recently published paper [J. Opt. Soc. Am. B 36, F84 (2019) [CrossRef] ] is corrected.

Equation (1) of our paper [1] contains a typographical error. The correct equation is as follows:

σ_{gr} = - \frac{q_{e}^{2} τ (1 - i ω τ)}{π ℏ^{2}} [\int_{- \infty}^{+ \infty} \frac{| E |}{{(1 - i ω τ)}^{2}} \frac{\partial F (E, μ_{ch})}{\partial E} d E + \int_{0}^{+ \infty} \frac{F (E, μ_{ch}) - F (- E, μ_{ch})}{{(1 - i ω τ)}^{2} + 4 τ^{2} E^{2} / ℏ^{2}} d E] .

The error does not affect the remainder of the paper. We apologize for any inconvenience caused by it.
