Emergence, symmetry, and ergodicity breaking in C60 fullerenesLee Liu

摘要: Polyatomic molecules comprise a unique class of composite quantum system that hosts emergent phenomena. Molecules feature perfect geometric symmetries and rotate freely in three dimensions. Additionally, they possess a hierarchy of energy scales spanning six orders of magnitude–(nuclear spin interactions), rotational, vibrational, electronic–that enable a spectroscopist to peel back successive layers of emergent behaviour and their underlying physics. This motivates broadband, frequency-domain spectroscopy of gas-phase molecules at the quantum state-resolved limit.
