Piezoelectric effects are how crystal radios work; AM Amplitude Modulated, shortwave, longwave
Quartz is dielectric.

> Electron–electron interactions in high-mobility conductors can give rise to transport signatures resembling those described by classical hydrodynamics. Using a nanoscale scanning magnetometer, we imaged a distinctive hydrodynamic transport pattern—stationary current vortices—in a monolayer graphene device at room temperature.

Are there phononic excitations from earthquake-induced piezoelectric and pyroelectric effects?
Do (surface) plasmon polaritons SPhP affect the interactions between quartz and gold, given heat and vibration as from an earthquake?
