Simulations of extended multi-chromophoric systems thus require a fast but reliable approximation scheme to calculate these dipole interactions. By means of a comparative study of the dipole approximation with quantum chemistry, we demonstrate that the usual line-dipole theory, while suitable for short molecules, breaks down for longer molecules with inter-molecular separations similar to or smaller than the length of the interacting chromophores; a limit that is typically found in conjugated polymer thin films. As a remedy, we propose an improved way of distributing the sub-dipole moments within a line which provides results in very good agreement with the quantum chemistry, and is still simple enough to be used in large scale simulations.</jats:p>"}],"status":"public","publisher":"AIP Publishing","date_updated":"2025-12-05T14:59:12Z","author":[{"last_name":"Denis","full_name":"Denis, Jean-Christophe","first_name":"Jean-Christophe"},{"orcid":"0000-0003-4042-4951","last_name":"Schumacher","full_name":"Schumacher, Stefan","id":"27271","first_name":"Stefan"},{"last_name":"Galbraith","full_name":"Galbraith, Ian","first_name":"Ian"}],"date_created":"2025-12-05T14:58:30Z","volume":137,"title":"Quantitative description of interactions between linear organic chromophores","doi":"10.1063/1.4768244","publication_status":"published","publication_identifier":{"issn":["0021-9606","1089-7690"]},"issue":"22","year":"2012","citation":{"ama":"Denis J-C, Schumacher S, Galbraith I.

The former is an approximation for the exchange–correlation contribution to the total energy functional in density-functional theory, and the latter is an approximation for the electronic self-energy in the framework of many-body perturbation theory. All implementations employ the mixed product basis, which has evolved into a versatile basis for the products of wave functions, describing the incoming and outgoing states of an electron that is scattered by interacting with another electron. It can thus be used for representing the nonlocal potential in hybrid functionals as well as the screened interaction and related quantities in GW calculations. In particular, the six-dimensional space integrals of the Hamiltonian exchange matrix elements (and exchange self-energy) decompose into sums over vector–matrix–vector products, which can be evaluated easily. The correlation part of the GW self-energy, which contains a time or frequency dependence, is calculated on the imaginary frequency axis with a subsequent analytic continuation to the real axis or, alternatively, by a direct frequency convolution of the Green function G and the dynamically screened Coulomb interaction W along a contour integration path that avoids the poles of the Green function. Hybrid-functional and GW calculations are notoriously computationally expensive. We present a number of tricks that reduce the computational cost considerably, including the use of spatial and time-reversal symmetries, modifications of the mixed product basis with the aim to optimize it for the correlation self-energy and another modification that makes the Coulomb matrix sparse, analytic expansions of the interaction potentials around the point of divergence at k=0, and a nested density and density-matrix convergence scheme for hybrid-functional calculations. We show CPU timings for prototype semiconductors and illustrative results for GdN and ZnO.
