Publication date: Available online 13 September 2019Source: Physics Letters AAuthor(s): Sherzod R. Otajonov, Eduard N. Tsoy, Fatkhulla Kh. AbdullaevAbstractThe dynamics of quantum droplets in 1D is analyzed on the basis of the variational approach (VA). It is shown that the VA based on the super-Gaussian function gives a good approximation of stationary states. The period of small oscillations of the perturbed droplet is obtained. It is found numerically that oscillations are almost undamped for many periods. Based on the VA, an existence of stable localized states for different combinations of signs of nonlinearities is demonstrated.
