Unifying reciprocal and real space atomic dynamics in dilute gases
Jaeyun Moon
In solids, quanta of atomic vibrations are identified in reciprocal space by their frequency and wavevector as phonons. At the opposite end of the matter spectrum, dynamics of dilu…

Collective nature of phonon energies in solids beyond harmonic oscillators
Jaeyun Moon, Leo Zella, Lucas Lindsay
Phonon quasi-particles have been monumental in microscopically understanding thermodynamics and transport properties in condensed matter for decades. Phonons have one-to-one corres…

Normal mode decomposition of atomic motion in solids
Jaeyun Moon
Decomposition of atomic motion into individual normal modes has led to remarkable success in microscopically understanding thermal properties and thermodynamics in simple solids. W…
