Quantum chemistry for quantum molecules In addition to Bose-Einstein condensates of atoms, researchers have recently realized the first Bose-Einstein condensate of molecules; a quantum gas of molecules. Such quantum gases can be used to simulate electrons in materials, or for the development of upcoming quantum technologies. However, the properties of the molecular quantum gas are largely unexplored. The researcher will develop new and unconventional methods to describe molecular quantum gases based on methods from quantum chemistry, where these are applied to electrons instead of molecules.
