Lee-Huang-Yang effects in the ultracold mixture of and with attractive interspecies interactions
The beyond-mean-field Lee-Huang-Yang (LHY) correction is ubiquitous in dilute ultracold
quantum gases. However, its effects are often elusive due to the typically much larger …

Modulational instability, inter-component asymmetry, and formation of quantum droplets in one-dimensional binary Bose gases
Quantum droplets are ultradilute liquid states that emerge from the competitive interplay of
two Hamiltonian terms, the mean-field energy and beyond-mean-field correction, in a weakly …
