The particle-hole map: formal derivation and numerical implementation
Yonghui Li, Carsten A. Ullrich
The particle-hole map (PHM) is a tool to visualize electronic excitations, based on representations in a canonical orbital transition space. Introduced as an alternative to the tra…
The particle-hole map: a computational tool to visualize electronic excitations
Yonghui Li, Carsten A. Ullrich
We introduce the particle-hole map (PHM), a visualization tool to analyze electronic excitations in molecules in the time or frequency domain, to be used in conjunction with time-d…
A minimal model for excitons within time-dependent density-functional theory
Zeng-hui Yang, Yonghui Li, Carsten A. Ullrich
The accurate description of the optical spectra of insulators and semiconductors remains an important challenge for time-dependent density-functional theory (TDDFT). Evidence has b…
Time-dependent V-representability on lattice systems
Yonghui Li, C. A. Ullrich
We study the mapping between time-dependent densities and potentials for noninteracting electronic systems on lattices. As discovered recently by Baer [J. Chem. Phys. 128, 044103 (…
