UCI scientists reveal mechanism of electron charge exchange in molecules

University of California, Irvine

Irvine, Calif., Oct. 14, 2019 – Researchers at the University of California, Irvine have developed a new scanning transmission electron microscopy method that enables visualization of the electric charge density of materials at sub-angstrom resolution. With this technique, the UCI scientists were able to observe electron distribution between atoms and molecules and uncover clues to the origins of ferroelectricity, the capacity of certain crystals to possess spontaneous electric polarization that can be switched by the application of an electric field.

Diversity May Be Key to Reducing Errors in Quantum Computing

Georgia Institute of Technology

In quantum computing, as in team building, a little diversity can help get the job done better. Georgia Tech researchers have found that by diversifying the types of errors produced by qubits, they can significantly improve the quality of computation results.

Complex Energies, Quantum Symmetries

Washington University in St. Louis

In a certain sense, physics is the study of the universe’s symmetries. Physicists strive to understand how systems and symmetries change under various transformations.New research from Washington University in St. Louis realizes one of the first parity-time (PT) symmetric  quantum systems, allowing scientists to observe how that kind of symmetry — and the act of breaking of it — leads to previously unexplored phenomena.

Newswise: The fast dance of electron spins

The fast dance of electron spins

University of Vienna

Metal complexes show a fascinating behavior in their interactions with light, which for example is utilized in organic light emitting diodes, solar cells, quantum computers, or even in cancer therapy. In many of these applications, the electron spin, a kind of inherent rotation of the electrons, plays an important role. Recently, the chemists Sebastian Mai and Leticia González from the Faculty of Chemistry of the University of Vienna succeeded in simulating the extremely fast spin flip processes that are triggered by the light absorption of metal complexes. The study is published in the journal "Chemical Science".
