I have submitted a publication to physics Letters A in the field of supersymmetric quantum mechanics (SUSYQM) my teacher says this is a pretty big deal but would like to hear some others opinion. I will obviously mention this when I apply but is it THAT big of a deal? Should I make a big deal about it when I apply? How much will it help me? I have some dumpy math grades from my sophomore year so I am worried about getting into a good school. What should I make of it?
