We study the formation of particle-imbalanced quantum droplets in aone-dimensional optical lattice containing a binary bosonic mixture at zerotemperature. To understand the effects of the imbalance from both the few- andmany-body perspectives, we employ density matrix renormalization group (DMRG)simulations and perform the extrapolation to the thermodynamic limit. Incontrast to the particle-balanced case, not all bosons are paired, resulting inan interplay between bound states and individual atoms that leads to intriguingphenomena. Quantum droplets manage to sustain a small particle imbalance,resulting in an effective magnetization. However, as the imbalance is furtherincreased, a critical point is eventually crossed, and the droplets start toexpel the excess particles while the magnetization in the bulk remainsconstant. Remarkably, the unpaired particles on top of the quantum dropleteffectively form a super Tonks-Girardeau (hard-rod) gas. The expulsion pointcoincides with the critical density at which the size of the superTonks-Girardeau gas matches the size of the droplet.
