The cover picture illustrates artistically an exciton state of the azobenzene aggregate, with the floor and glowing bars showing the “fraction of transition density matrix” matrix, characterizing the exciton state. In the article number 2200907, Evgenii Titov and Alkit Beqiraj have extensively studied the exciton states of azobenzene aggregates using quantum chemical calculations.
