Atomic dynamics in fluids: Normal mode analysis revisited
Jaeyun Moon, Lucas Lindsay, Takeshi Egami
Developing microscopic understanding of the thermal properties of liquids is challenging due to their strong dynamic disorder, which prevents characterization of the atomic degrees…
Microscopic view of heat capacity of matter: solid, liquid, and gas
Jaeyun Moon, Simon Thébaud, Lucas Lindsay +1
Understanding thermodynamics in liquids at the atomic level is challenging because of strong atomic interactions and lack of symmetry. Recent prior theoretical works have focused o…
Transient Nature of Fast Relaxation in Metallic Glass
Leo Zella, Jaeyun Moon, David Keffer +1
Metallic glasses exhibit fast mechanical relaxations at temperatures well below the glass transition, one of which shows little variation with temperature known as nearly constant…
Structural effect on phonon attenuation in metallic liquids and glasses
Jaeyun Moon, Takeshi Egami
The attenuation rate of vibrational excitations in various metallic liquids and glasses has been reported to change from the quadratic dependence on wavevector at low wavevectors t…
Examining normal modes as fundamental heat carriers in amorphous solids: the case of amorphous silicon
Jaeyun Moon
Normal mode decomposition of atomic vibrations has been used to provide microscopic under-standing of thermal transport in amorphous solids for decades. In normal mode methods, it…
Origin of micron-scale propagation lengths of heat-carrying acoustic excitations in amorphous silicon
Taeyong Kim, Jaeyun Moon, Austin J. Minnich
The heat-carrying acoustic excitations of amorphous silicon are of interest because their mean free paths may approach micron scales at room temperature. Despite extensive investig…
Propagating elastic vibrations dominate thermal conduction in amorphous silicon
Jaeyun Moon, Benoit Latour, Austin Minnich
Thermal atomic vibrations in amorphous solids can be distinguished by whether they propagate as elastic waves or do not propagate due to lack of atomic periodicity. In a-Si, prior…
Sub-amorphous thermal conductivity in amorphous heterogeneous nanocomposites
Jaeyun Moon, Austin J. Minnich
Pure amorphous solids are traditionally considered to set the lower bound of thermal conductivity due to their disordered atomic structure that impedes vibrational energy transport…
