Ultrafast intersystem crossing in nickel porphyrins
Javier Fernandez-Rodriguez, Jun Chang, Arthur J. Fedro +1
We study the relaxation dynamics and intersystem-crossing to the metastable state in laser-pumped tetra and hexa-coordinated nickel porphyrins. We use a ligand-field model which ta…
A probability-conserving dissipative Schrödinger equation
Michel van Veenendaal, Jun Chang, A. J. Fedro
Dissipative effects on a microscopic level are included in the Schrödinger equation. When the decay between different local levels as a result of the coupling to a bath, the Schröd…
Ultrafast Cascading Theory in Intersystem Crossings in Transition-Metal Complexes
Jun Chang, A. J. Fedro, Michel van Veenendaal
We investigate the cascade decay mechanism for ultrafast intersystem crossing mediated by the spin-orbit coupling in transition-metal complexes. A quantum-mechanical description of…
Ultrafast Electron Dynamics Theory of Photo-excited Ruthenium Complexes
Jun Chang, A. J. Fedro, Michel van Veenendaal
An explanation is provided for the ultrafast photo-excited electron dynamics in low-spin Ruthenium (II) organic complexes. The experimentally-observed singlet to triplet decay in t…
Fast Intersystem Crossing in Transition-Metal Complexes
Michel van Veenendaal, Jun Chang, A. J. Fedro
The mechanism behind fast intersystem crossing in transition-metal complexes is shown to be a result of the dephasing of the photoexcited state to the phonon continuum of a differe…
Dynamics and Spectral Weights of Shake-up Valence Excitations in Transition Metal K-edge Resonant Inelastic X-ray Scattering
K. H. Ahn, A. J. Fedro, Michel van Veenendaal
Using a model Hamiltonian, we discuss how we could interpret data obtained from transition metal -edge resonant inelastic x-ray scattering (RIXS) experiments. By analyzing the c…
Charge melting and polaron collapse in
L. Vasiliu-Doloc, S. Rosenkranz, R. Osborn +7
X-ray and neutron scattering measurements directly demonstrate the existence of polarons in the paramagnetic phase of optimally-doped colossal magnetoresistive oxides. The polarons…
