Frequency-selective amplification of nonlinear response in strongly correlated bosons
We present a protocol to generate enhanced nonlinear responses of incident pulses in the density wave phase within the extended Bose-Hubbard model using the concept of resonance-induced amplification. This method enables the selection of an incident pulse frequency to amplify the desired harmonic order. We characterize the enhancement of the nonlinear harmonic spectra under various frequencies and field strengths of the incident pulses and demonstrate that an optimal field strength is necessary to realize our protocol.
