Abstract
This erratum corrects the acronym ‘ISW’ as ’infinite square well’.
© 2020 Optical Society of America
The sentence “the effect of including the ISW potential in $z$” on page 4 of our Letter [1] should be written as “the effect of including the infinite square well potential in $z$,” since the acronym is not defined explicitly.
