Which outcome occurs when increased pressure distorts crystal phonon dispersion?

A)Reduced Cooper pair formation temperature
B)Increased electron-hole recombination efficiency
C)Enhanced exciton binding energy observed
D)Suppressed Bloch wave transport length

💡 Explanation

Phonon dispersion changes effect vibrational modes influencing Cooper pair formation during Fröhlich interaction, because lattice changes modify electron-phonon coupling causing higher-frequency phonons; therefore, reduced Cooper pair temperature, rather than the other options, arises due to altered electron interaction.
