Observation of coherent delocalized phonon-like modes in DNA under physiological conditions [PDF]
, 2016 Underdamped terahertz-frequency delocalized phonon-like modes have long been suggested to play a role in the biological function of DNA. Such phonon modes involve the collective motion of many atoms and are prerequisite to understanding the molecular ...
