Please find here our latest paper. If this was a romance, it would be a story about how the life of two friends (phonon and photon), who are forced to have many interactions because they share a tight room (the cavity), changes dramatically when a visitor comes (the “free” electron). As it is a scientific paper, it describes how vibrational strong coupling is affected by an insulator-to-metal transition in 1T-TaS2! Link to the paper
