Abstract
A roton-maxon character of the excitation spectrum, shown by dipolar condensates, was studied. Bragg-spectroscopy was used to investigate the presence of the roton minimum in the excitation spectrum. The tunability of the presence, position, and depth of the roton minimum were explained by the variations in the density, confining potential, and the short-range coupling strength.
