As often witnessed in the past, progress in applied physics has been promoted by cross-disciplinary research and for this reason we believe that it is significant to give readers a broad perspective on current research. As a first step in this direction, each month we will select and suggest a small number of articles for the registered readers by using alert e-mails named “SPOTLIGHTS”. Selection of papers is based on the high potentialities for capturing interest of researchers in the applied physics community, not on the papers' evaluation. We hope that “SPOTLIGHTS” will lead to opportunities to redirect readers beyond their usual interests.
