We investigate the breathing mode and the stability of a quantum droplet in atightly trapped one-dimensional dipolar gas of bosonic atoms. When the dropletwith a flat-top density profile is formed, the breathing mode frequency scalesas the inverse of the number of atoms in the cloud. This is straightforwardlyderived within a phenomenological hydrodynamical approach and confirmed usingboth a variational method based on a generalized Gross-Pitaevskii actionfunctional and the sum-rule approach. We extend our analysis also to thepresence of axial confinement showing the effect of the trap on the densityprofile and therefore on the breathing mode frequency scaling. Our analysisconfirms the stability of the quantum droplet against the particles emissionwhen the flat-top density profile is observed. Our results can be used as aguide to the experimental investigations of collective modes to detect theformation of quantum droplets in quasi-one-dimensional dipolar gases.
