We propose a novel gravitational wave detection mechanism based on the theoretical interaction between gravitational waves and crystal phonons in modified transition edge sensors (TES). This approach exploits the continuous gravitational wave emission from the Sun–Earth system to provide a predictable test source. The detection principle relies on gravitational wave-induced modulation of phonon populations in crystalline materials, particularly ionic crystals like NaCl, which could manifest as measurable shifts in the critical temperatures of superconducting detectors. We present detailed theoretical calculations for phonon–gravitational wave coupling mechanisms, including quadrupolar deformation, induced polarization effects, and parametric amplification. While the proposed interaction cross-sections are extraordinarily small, quantum coherent effects operating over extended observation periods might enable statistical detection of phonon population changes. This work represents highly speculative physics requiring unprecedented experimental sensitivity.
