Abstract

Time-dependent coupled-cluster method with time-varying orbital functions, called time-dependent optimized coupled-cluster (TD-OCC) method, is successfully formulated for multielectron dynamics in an intense laser field [1]. We have derived the equations of motion for CC amplitudes and orthonormal orbital functions based on the manifestly real action functional, and implemented the method including double excitations (TD-OCCD) and double and triple excitations (TD-OCCDT) with finite-element discrete-variable-representation (FEDVR) basis.
