Quantum tomography of molecules using ultrafast electron diffraction
Jiayang Jiang, Ming Zhang, Aosheng Gu +2
We propose a quantum tomography (QT) approach to retrieve the temporally evolving reduced density matrix in elecotronic state basis, where the populations and coherence between gro…
Synthesis technique and electron beam damage study of nanometer-thin single-crystalline Thymine
Hazem Daoud, Sreelaja Pulleri Vadhyar, Ehsan Nikbin +2
Samples suitable for electron diffraction studies must satisfy certain characteristics such as having a thickness in the range of 10 - 100 nm. We report, to our knowledge, the firs…
Unraveling Quantum Coherences Mediating Primary Charge Transfer Processes in Photosystem II Reaction Center
