Generalization of the multiconfigurational time-dependent Hartree method to nonadiabatic systems
We present a generalization of the multiconfigurational time-dependent Hartree ~MCTDH! scheme, originally introduced by Meyer, Manthe and Cederbaum @Chem. Phys. Lett. 165, 73 ~1990!#, to a general nonadiabatic system. In the course of deriving the extended working equations a new compact notation is introduced. Subsequently the equations of motion are applied to a one-dimensional two-surface mo...
متن کاملA multiconfigurational time-dependent Hartree-Fock method for excited electronic states. II. Coulomb interaction effects in single conjugated polymer chains.
Conjugated polymers have attracted considerable attention in the last few decades due to their potential for optoelectronic applications. A key step that needs optimisation is charge carrier separation following photoexcitation. To understand better the dynamics of the exciton prior to charge separation, we have performed simulations of the formation and dynamics of localised excitations in sin...
متن کاملA multiconfigurational time-dependent Hartree-Fock method for excited electronic states. I. General formalism and application to open-shell states.
The solution of the time-dependent Schrödinger equation for systems of interacting electrons is generally a prohibitive task, for which approximate methods are necessary. Popular approaches, such as the time-dependent Hartree-Fock (TDHF) approximation and time-dependent density functional theory (TDDFT), are essentially single-configurational schemes. TDHF is by construction incapable of fully ...
متن کاملStatistics of indistinguishable particles.
The wave function of a system containing identical particles takes into account the relationship between a particle's intrinsic spin and its statistical property. Specifically, the exchange of two identical particles having odd-half-integer spin results in the wave function changing sign, whereas the exchange of two identical particles having integer spin is accompanied by no such sign change. ...
متن کاملTime-dependent Hartree approaches for the study of intramolecular dynamics in dimer systems
We apply and the time-dependent Hartree ~TDH! method to the study of intramolecular dynamics in dimer systems. The HCl dimer is chosen as test case. Model calculations are performed on reduced dimensional representation of this system namely two-, three-, and four-dimensional ones. We assess the validity of different implementations of the TDH method including the account of direct correlations...
