Linear-response time-dependent density functional theory approach to warm dense matter with adiabatic exchange-correlation kernels

چکیده
We present a new methodology for the linear-response time-dependent density functional theory (LR-TDDFT) calculation of dynamic response function warm dense matter in an adiabatic approximation that can be used with any available exchange-correlation (XC) across Jacob's Ladder and temperature regimes. The main novelty presented approach is it go beyond local (ALDA) generalized LDA (AGGA) while preserving self-consistence between Kohn-Sham (KS) XC kernel extended systems. key ingredient method combination from direct perturbation macroscopic KS standard LR-TDDFT using orbitals. demonstrate application example hydrogen, which we perform detailed analysis function, RPA result, total kernel. performed LDA, GGA, meta-GGA level approximations effects. directly applicable to disordered systems such as liquid metals, matter, plasmas.

Adiabatic approximation of time-dependent density matrix functional response theory.
Time-dependent density matrix functional theory can be formulated in terms of coupled-perturbed response equations, in which a coupling matrix K(omega) features, analogous to the well-known time-dependent density functional theory (TDDFT) case. An adiabatic approximation is needed to solve these equations, but the adiabatic approximation is much more critical since there is not a good "zero ord...

متن کاملReal-time linear response for time-dependent density-functional theory.
We present a linear-response approach for time-dependent density-functional theories using time-adiabatic functionals. The resulting theory can be performed both in the time and in the frequency domain. The derivation considers an impulsive perturbation after which the Kohn-Sham orbitals develop in time autonomously. The equation describing the evolution is not strictly linear in the wave funct...

In this paper we propose an extension of the self-consistent charge-density-functional tight-binding ~SCCDFTB! method @M. Elstner et al., Phys. Rev.

For a test set of small organic molecules low-lying singlet excitation energies are com...
متن کاملDouble excitations within time-dependent density functional theory linear response.
Within the adiabatic approximation, time-dependent density functional theory yields only single excitations. Near states of double excitation character, the exact exchange-correlation kernel has a strong dependence on frequency. We derive the exact frequency-dependent kernel when a double excitation mixes with a single excitation, well separated from the other excitations, in the limit that the...
