Hello, I am currently writing a paper for submission to the PRL. I wish to put in a note after the names of the first two authors, stating "These authors have contributed equally to this work". I would like to solicit the help of the Physics Forums community in knowing how to do this. In some previous PRL papers I have seen, this is denoted by an asterisk after the authors' names, the explicatory text to which is then placed just before the references (after the horizontal mark denoting the end of the paper). I have been fiddling around with the REVTeX 4.1 template for a while now, but cannot seem to get this note correctly. I would be grateful for any help.
