Title: An Overview of Real-Time Time-Dependent Coupled-Cluster Methods
Abstract: Real-time time-dependent electronic structure methods model electron dynamics induced by time-dependent electromagnetic fields by solving the time-dependent Schrödinger in the time-domain. During my time as a Ph.D. student at the Hylleraas Centre for Quantum Molecular Sciences, I have worked with real-time time-dependent coupled-cluster methods. These methods come in different variants with subtle differences. For example, RTTDCC methods can be formulated either with static or time-evolving orbitals. Also, one can formulate approximations to specific orders of the theory based on perturbation theory. In this talk, I will attempt to provide an overview of some of the different RTTDCC methods and their properties.
