“…Recently, this mapping was leveraged for the deterministic realization of Townes solitons in a 2D Bose mixture [29], by making judicious use of the almost coincidence of the various interaction strengths (see also [30] for another preparation protocol of the Townes soliton with matter waves and [31] for a general review). This approach was also put forward for the realization of other exotic nonlinear excitations, such as Peregrine solitons [32] or dark-bright soliton trains [33].…”

When two Bose-Einstein condensates – labelled 1 and 2 – overlap spatially, the equilibrium state of the system depends on the miscibility criterion for the two fluids. Here, we theoretically focus on the non-miscible regime in two spatial dimensions and explore the properties of the localized wave packet formed by the minority component 2 when immersed in an infinite bath formed by component 1. We address the zero-temperature regime and describe the two-fluid system by coupled classical field equations. We show that such a wave packet exists only for an atom number N 2 above a threshold value corresponding to the Townes soliton state. We identify the regimes where this localized state can be described by an effective single-field equation up to the droplet case, where component 2 behaves like an incompressible fluid. We study the near-equilibrium dynamics of the coupled fluids, which reveals specific parameter ranges for the existence of localized excitation modes.

In this topical review paper we provide a survey of classical and more recent results on the IST for one-dimensional scalar, vector and square matrix NLS systems on the line ($$-\infty<x<\infty$$ - ∞ < x < ∞ ) with certain physically relevant non-zero boundary conditions at space infinity, discuss some new developments and applications, and offer some perspectives about future directions on the subject.
