What does the word 'macropscopic' mean in it's abstract? The best bet is a typo of macroscopic - but hmm it's made it through that far and I do find a bunch of other uses of that word in physicsy stuff
(The nice word in there is 'ansatzes' which I didn't know, as something like a starting guess/assumption)
Guessing: macropscopic is a typo. Most dictionaries don't have many technical words and you get use to click "add to dictionary". After a few days it's not highlighted in any of the authors or reviewers text editor and nobody notice it. If you want to get fancy, call it "click fatigue".
