The emergent oscillatory motion appears to be highly sensitive to temperature. Moreover, it is shown that the emergent uniform rotation without any angular momentum, can be described in an effective theory approach as an autonomous Hamiltonian time crystal. It is proposed that the observed behavior is universal in the case of triangular molecules. In the limit of very long stroboscopic time steps the entire molecule can then rotate in an apparent uniform fashion, but with no angular momentum. The oscillation period increases in a self-similar manner when the length of the stroboscopic time step is increased. The period of oscillation is emergent and intrinsic to the molecule so that this self-organization bears resemblance to a driven time crystal. equidistant time steps, the random thermal vibrations of the individual atoms become self-organized into a collective oscillatory motion of the entire molecule. When the molecule is observed stroboscopically, at discrete. For this the thermal vibrations of individual atoms in an isolated cyclopropane molecule are simulated in vacuum and at ultra-low internal temperature values.

Here the first all-atom level molecular dynamics example of this phenomenon is presented. Read moreĪ deformable body can rotate even with no angular momentum simply by changing its shape. As such it has potential applications that range from models of autonomous molecular motors to development of molecular level detector, sensor and control technologies. The phenomenon is a temperature sensitive measurable. This large time scale rotational motion is then modeled in an effective theory approach, in terms of timecrystalline Hamiltonian dynamics. It is observed that in the limit of long stroboscopic time steps the vibrations combine into an apparent uniform rotation of the entire molecule even in the absence of angular momentum. values, and the ensuing molecular motion is followed stroboscopically. For this the thermal vibrations of individual atoms in an isolated cyclopropane molecule are simulated in vacuum and at ultralow internal temperature. Here a first principles molecular level example of the phenomenon is presented. A good example is a falling cat, how it maneuvers in air to land on its feet.

He was awarded the 1965 Nobel Prize for his work on the development of quantum field theory. Feynman was Richard Chace Tolman Professor of Theoretical Physics at the California Institute of Technology.
