NMR sidebands induced by electromechanical phonons. a A red (blue) sideband NMR peak can be induced with the absorption (emission) of an electromechanical phonons. b–d The main and red/blue sideband NMR spectra with relevant isotopes, 75As, 69Ga, and 71Ga from top to bottom, respectively. Each panel shows ΔIsd as function of ωRF with ωR(B) = ω0−(+)ωM, where ω0(75As)/2π = 22.63 MHz, ω0(69Ga)/2π = 31.79 MHz, and ω0(71Ga)/2π = 40.39 MHz at B0 = 3.1 T when the resonator is driven with Va = 40 mV at point 5 in Fig. 3a. The solid lines in the sideband NMR spectra show Gaussian fits of the data. e The simulated NMR spectra for 69Ga using the rotating-wave approximation, which are normalized by the amplitude of the main NMR peak (see Methods)
