About Paper:

This project seeks to develop an acoustic equivalent to laser-based ultrafast spectroscopy, focusing on two- dimensional infrared spectroscopy. Early experiments reveal that the anharmonic behavior of stringed instruments, like guitars, can be analyzed using pump-probe type measurements. In these measurements, phase-controlled sound pulses of different amplitudes create nonlinear acoustic excitations within the instrument. These experiments offer a quantitative measure of acoustic anharmonicities, such as the "buzzing" from a poorly adjusted guitar string. The objective is to advance this research to encompass full two- dimensional measurements, detailing the nonlinear coupling and energy transfer between strings. Additionally, we hope to demonstrate the connection between quantum and classical nonlinear response. Keywords: Physics; Quantum; Nonlinear; Acoustic; Spectroscopy
