After comparing the pQED method with existing sc-QED approaches, we move toward a discussion of computing and manipulating polaritonic properties in the excited state for interesting chemical and physical processes. Fig. showcases one such example where the intention is to compute various excited state quantities such as the natural transition orbitals (NTOs), transition density matrix, and transition density, which are commonly utilized in the electronic structure community to interpret excitations in molecular systems. See Theoretical Details for more information on the computation of these quantities. In particular, we aim to showcase how one is able to manipulate the character and energetic alignment of an exited charge transfer state (which is optically inactive) via coupling a nearby excited state with non-zero oscillator strength to the cavity.
