Hello, the professor supervising my bachelor thesis is happy with the results. Together with another co-author, he is currently writing a paper for Physical Review Letters and is considering adding my results to it. However, for this purpose, he needs more general results. In other words, if I want my name on that paper, I would have to put in some work for this in the summer. I am aspiring to make a career in theoretical physics. I do not mind a little extra work (I also have other academic plans for the summer). However, I will very probably be the last of three in the authors list. Do you think this is worth the pains? What is the value of one's name appearing on a PRL paper, especially with regard to a career in theoretical physics? May it come in handy e.g. when applying for a doctorate position or possibly even for a master thesis position abroad?
