Abstract

We Unravel The Existence And Stability Properties Of Dark Soliton Solutions As They Extend From The Regime Of Trapped Quantum Droplets Towards The Thomas-Fermi Limit In Homonuclear Symmetric Bose Mixtures. Leveraging A Phase-Plane Analysis, We Identify The Regimes Of Existence Of Different Types Of Quantum Droplets And Subsequently Examine The Possibility Of Black And Gray Solitons And Kink-Type Structures In This System. Moreover, We Employ The Landau Dynamics Approach To Extract An Analytical Estimate Of The Oscillation Frequency Of A Single Dark Soliton In The Relevant Extended Gross-Pitaevskii Model. Within This Framework, We Also Find That The Single Soliton Immersed In A Droplet Is Stable, While Multisoliton Configurations Exhibit Parametric Windows Of Oscillatory Instabilities. Our Results Pave The Way For Studying Dynamical Features Of Nonlinear Multisoliton Excitations In A Droplet Environment In Contemporary Experimental Settings.
