The spin polarized linear response from density functional theory: Theory and application to atoms
Abstract
Within the context of spin polarized conceptual density functional theory, the spin polarized linear response functions are introduced both in the [N, N{sub s}] and [N{sub α}, N{sub β}] representations. The mathematical relations between the spin polarized linear response functions in both representations are examined and an analytical expression for the spin polarized linear response functions in the [N{sub α}, N{sub β}] representation is derived. The spin polarized linear response functions were calculated for all atoms up to and including argon. To simplify the plotting of our results, we integrated χ(r, r′) to a quantity χ(r, r{sup ′}), circumventing the θ and ϕ dependence. This allows us to plot and to investigate the periodicity throughout the first three rows in the periodic table within the two different representations. For the first time, χ{sub αβ}(r, r{sup ′}), χ{sub βα}(r, r{sup ′}), and χ{sub SS}(r, r{sup ′}) plots have been calculated and discussed. By integration of the spin polarized linear response functions, different components to the polarisability, α{sub αα}, α{sub αβ}, α{sub βα}, and α{sub ββ} have been calculated.

Examining photochemical processes in solution requires understanding the solvent effects on the potential energy profiles near conical intersections (CIs). For that purpose, the CI point in solution is determined as the crossing between nonequilibrium free energy surfaces. In this work, the nonequilibrium free energy is described using the combined method of linearresponse free energy and collinear spinflip timedependent density functional theory. The proposed approach reveals the solvent effects on the CI geometries of stilbene in an acetonitrile solution and those of thymine in water. Polar acetonitrile decreases the energy difference between the twisted minimum and twistedpyramidalized CI of stilbene. Formore »

Modified linear response for timedependent densityfunctional theory: Application to Rydberg and chargetransfer excitations
We present an improved ab initio timedependent densityfunctional theory (TDDFT) approach to electronic excitations. A conventional TDDFT scheme within the localdensity approximation (LDA) inaccurately predicts Rydberg and chargetransfer excitation energies, mainly because the electronhole (eh) interaction is inappropriately described in these excitations, as can be found by analyzing the linear response formula [M. Petersilka, U. J. Gossmann, and E. K. U. Gross, Phys. Rev. Lett. 76, 1212 (1996)]. When the formula is averaged over the electron occupation, the inappropriate eh interaction within LDA is corrected to become explicitly similar to that of the exact exchange system. As anticipated from themore » 
Sequential double excitations from linearresponse timedependent density functional theory
Traditional UV/vis and Xray spectroscopies focus mainly on the study of excitations starting exclusively from electronic ground states. However there are many experiments where transitions from excited states, both absorption and emission, are probed. In this work we develop a formalism based on linearresponse timedependent density functional theory to investigate spectroscopic properties of excited states. We apply our model to study the excitedstate absorption of a diplatinum(II) complex under Xrays, and transient vis/UV absorption of pyrene and azobenzene.
