Abstract: Longitudinal and transverse modes of thermal disturbances in isotopically pure alkalihalide crystals are derived from phonon hydrodynamics. GuyerKrumhansl (GK) model of phonon scattering is first recovered by relating the first and second viscosity to the relaxation times. Helmholtz potentials are then introduced to split the two modes from the heat flux vector. It has been found that the scalar potential coincides with the heat equation in the dualphaselag model, while the vector potential describes dispersive transverse phonons and introduces a new type of equation in microscale heat transfer.
