Australian researchers use quantum computers to simulate the behavior of real molecules
Graphical abstract. Credit: Journal of the American Chemical Society (2025). doi:10.1021/jacs.5c03336 When molecules absorb light, they receive a whirlwind of quantum mechanical transformation. Electrons jump between energy levels, oscillations of atoms, and chemical bonds, all within 10 seconds. These processes support everything from photosynthesis in plants to DNA damage caused by sunlight, to solar cell surgery and light-driven cancer therapy.…

A new strategy to simulate nonadiabatic dynamics of molecules on metal surfaces
Schematic workflow for nonadiabatic dynamics simulation of a molecule (e.g. CO) on a metal surface. Credit: Prof. Jiang’s team The team proposed a new approach to accurately describe the nonadiabatic dynamics of molecular electron transfer at metal surfaces. Their work was published in Physical Review Letters. Numerous experimental phenomena have demonstrated that nonadiabatic energy transfer is widespread in various interfacial…
