Göttingen scientists image 3D wavefunction of organic molecule

Researchers at the University of Göttingen have imaged the three-dimensional wavefunction of an organic molecule only nanometers in size. The team combined advanced photoelectron spectroscopy with redesigned algorithms to reconstruct the complete molecular orbital. The method uses a lab-based soft-X-ray source, removing the need for synchrotron facilities.

Key Facts

The University of Göttingen team imaged the 3D wavefunction of an organic molecule only nanometers in size.
The researchers combined photoelectron spectroscopy with redesigned computer algorithms to reconstruct the complete molecular orbital.
The experiment uses a lab-based soft-X-ray light source that provides ultrashort light pulses, eliminating the need for synchrotron facilities.
The findings were published in Nature Communications.

Imaging Method

The wavefunction itself cannot be directly observed or measured, so the researchers used photoelectron spectroscopy to measure the momentum of electrons emitted from the molecule. This technique provides access to one half of the wavefunction without physically changing its state. Advanced computer algorithms were then used to reconstruct the missing half, producing an image of the complete molecular orbital. The reconstructed image distinguishes features smaller than the distance separating carbon atoms within the molecule.

Technical Advances

Dr. Matthijs Jansen, co-leader of the study, said the team introduced two powerful new concepts. The computer algorithm was redesigned from the ground up, allowing reliable 3D images to be obtained with much less experimental data. The experiment is based on a powerful, lab-based soft-X-ray light source that provides ultrashort light pulses. Previously, extending this approach into three dimensions required lengthy measurements at major synchrotron research facilities.

Physical Review Letters study confirms photons can spend negative time in atoms

Researchers publishing in Physical Review Letters have shown that photons passing through a cloud of rubidium atoms can emerge earlier than expected, corresponding to a negative dwell time. Weak measurements of the atoms themselves confirmed the result, ruling out an illusion. The finding does not break standard physics but reveals that a quantum strangeness is measurable.

Imperial College researchers unveil Clavina reconfigurable quantum processor in Nature Photonics

Researchers from Imperial College London develop a programmable photonic quantum processor, dubbed Clavina, that combines linear and nonlinear operations within a single reconfigurable architecture, according to a study published 6 August in Nature Photonics. The team demonstrates the processor’s versatility by simulating the Bose-Hubbard model in condensed matter physics and generating Gottesman-Kitaev-Preskill states for more reliable quantum error correction.
