Comet 67P/Churyumov-Gerasimenko rotation changes derived from sublimation induced torques
Tobias Kramer, Matthias Laeuter, Stubbe Hviid +3
(Context) The change of the rotation period and the orientation of the rotation axis of comet 67P/Churyumov-Gerasimenko (67P/C-G) is deducible from images taken by the scientific i…
Modeling of Transient Absorption Spectra in Exciton Charge-Transfer Systems
Tobias Kramer, Mirta Rodriguez, Yaroslav Zelinskyy
Time-resolved spectroscopy provides the main tool for analyzing the dynamics of excitonic energy transfer in light-harvesting complexes. To infer time-scales and effective coupling…
Machine Learning of Two-Dimensional Spectroscopic Data
Mirta Rodríguez, Tobias Kramer
Two-dimensional electronic spectroscopy has become one of the main experimental tools for analyzing the dynamics of excitonic energy transfer in large molecular complexes. Simplifi…
Energy flow in the Photosystem I supercomplex: comparison of approximative theories with DM-HEOM
Tobias Kramer, Matthias Noack, Jeffrey R Reimers +3
We analyze the exciton dynamics in PhotosystemI from Thermosynechococcus elongatus using the distributed memory implementation of the hierarchical equation of motion (DM-HEOM) for…
Surface localization of gas sources on comet 67P/Churyumov-Gerasimenko based on DFMS/COPS data
Matthias Laeuter, Tobias Kramer, Martin Rubin +1
We reconstruct the temporal evolution of the source distribution for the four major gas species H2O, CO2, CO, and O2 on the surface of comet 67P/Churyumov-Gerasimenko during its 20…
Efficient calculation of open quantum system dynamics and time-resolved spectroscopy with Distributed Memory HEOM (DM-HEOM)
Tobias Kramer, Matthias Noack, Alexander Reinefeld +2
Time- and frequency resolved optical signals provide insights into the properties of light harvesting molecular complexes, including excitation energies, dipole strengths and orien…
