Incorrect version:
In this paper, we study quantum droplets in one dimension under the influence of spacetime curvature by
redefining the momentum operator, resulting in a maximum length and a minimum momentum, consistent
with anti-de Sitter space (AdS). By examining this effect through the αparameter on the exact solution of
free quantum droplets, we found that the relationship between the number of atoms and the chemical potential
differs from the ordinary case. Additionally, we discovered that the flat-top shape can disappear and transform
into a Gaussian shape in the presence of the maximum length (minimum momentum). Moreover, we found that
the interaction of quantum droplets with spacetime curvature causes them to have a larger size. We also studied
this effect on the variational solution via Gaussian ansatz for small droplets, we concluded that αdecreases
the stability and self-localisation of the quantum droplets.
Corrected version:
This paper investigates the influence of position-dependent effective mass (PDM) on one-dimensional
Bose-Einstein condensates (BECs) using the Von Roos approach. Both variational and numerical methods
are employed to solve the underlying generalized discrete GrossPitaevskii equation. We derive analytical
expressions for the energy functional and chemical potential under both null potential and Gaussian potential
well, demonstrating the impact of PDM. Our analysis confirms that the selected expression for PDM diminishes
system stability and restricts the spatial range of atom distribution within the condensate.

We present a full set of wave equations describing a dense Bose fluid, applicable both to non- ideal gases and to liquid 4He. The phonon spectrum in liquid 4He is found and the fraction of condensed particles is calculated at zero temperature for a wide range of densities. The theory also yields the ground-state energy for the quantum liquid 4He in agreement to high accuracy with Monte Carlo simulations and experimental data at low pressure. We also present the derivation of a generalized Hartree-Fock equation describing roton clusters in low temperature liquid 4He, allowing us to confirm that, at low enough temperatures and for a wide range of pressures, the stable clusters consist of 13 bound atoms.

This review paper presents an overview of the theoretical and experimental progress on the study of matter-wave dark solitons in atomic Bose-Einstein condensates. Upon introducing the general framework, we discuss the statics and dynamics of single and multiple matter-wave dark solitons in the quasi one-dimensional setting, in higher-dimensional settings, as well as in the dimensionality crossover regime. Special attention is paid to the connection between theoretical results, obtained by various analytical approaches, and relevant experimental observations.

We provide a mathematical proof of the existence of traveling vortex rings solutions to the Gross-Pitaevskii (GP) equation in dimension N greater than or equal to 3. We also extend the asymptotic analysis of the free field Ginzburg-Landau equation to a larger class of equations, including the Ginzburg-Landau equation for superconductivity as well as the traveling wave equation for GP. In particular we rigorously derive a curvature equation for the concentration set (i.e. line vortices if N = 3).

. The quantum description of a Bose-Einstein condensates in double-well traps connected by a Josephson junction is discussed. The quantization in terms of the number and phase canonically-conjugated operators gives correct energy levels, but results in finite phase fluctuations in the absence of interaction. This seems to contradict the perfect coherence of a system of non-interacting particles. The problem can be solved by calculating the observables that characterize the coherence properties of a system, as, for example, the momentum distribution. It occurs that the visibility of interference fringes depends both on the fluctuations of the phase and the number of atoms. The visibility is calculated in the limit of small interaction and the results exhibit the correct behavior.

The steady-state self-effect of wave beams is analyzed in a weakly ionized plasma in which nonlinear effects due to heating and ionization are governing. The thermal self-effect of the beam is analyzed numerically on a computer and in the aberrationless approximation. The self-focusing of axisymmetric beams is analyzed, and its quantitative characteristics are determined. The conditions for the instability of a broad beam (or plane wave) with respect to breakup into ''narrower'' beams are determined for the case of a nonlocal nonlinearity. The influence on the instability of an oppositely directed (reflected) wave is determined. The influence of additional ionization on the propagation of a wave beam is studied.

We investigate the dynamics of Bose-Einstein condensate bright solitons made of alkali-metal atoms with negative scattering length and under harmonic confinement in the transverse direction. Contrary to the one-dimensional (1D) case, the 3D bright soliton exists only below a critical attractive interaction that depends on the extent of confinement. Such a behavior is also found in multisoliton condensates with box boundary conditions. We obtain numerical and analytical estimates of the critical strength beyond which the solitons do not exist. By using an effective 1D nonpolynomial nonlinear Schrödinger equation, which accurately takes into account the transverse dynamics of cigarlike condensates, we numerically simulate the dynamics of the “soliton train” reported in a recent experiment [Nature (London) 417, 150 (2002)]. Then, analyzing the macroscopic quantum tunneling of the bright soliton on a Gaussian barrier, we find that its interference in the tunneling region is strongly suppressed with respect to nonsolitonic case; moreover, the tunneling through a barrier breaks the shape invariance of the matter wave. Finally, we show that the collapse of the soliton is induced by the scattering on the barrier or by the collision with another matter wave when the density reaches a critical value, for which we derive an accurate analytical formula.

Based on the system of equations for the Bose–Einstein condensate to the third order in the interaction radius, a nonlinear integro-differential equation of the third order, whose particular case is the Korteweg–de Vries equation to the first order in the interaction radius, is obtained. The profile of nonlinear stationary perturbations of boson concentration in a system with short-range interaction potential is found and investigated, and the corresponding expression for the wave function in the medium is obtained.

Dipolar interactions support the formation of inter-site soliton molecules in a stack of quasi-1D traps. We show that the stability and properties of individual solitons, and soliton molecules in such a geometry crucially depend on the interplay between contact and dipolar interactions. In particular, two different quasi-1D soliton regimes are possible: a 1D soliton characterized by purely repulsive DDI and a 3D soliton for which a sufficiently large dipole moment renders the DDI attractive. Furthermore, we find that contrary to the case of dimers of polar molecules, the soliton dimers exhibit a nontrivial behavior of the elementary excitations that stems from the competition between on-site and inter-site DDI. Finally, we prove the existence of soliton trimers in a regime where molecular trimers do not occur. We demonstrate that the soliton molecules that we report are well feasible under realistic experimental conditions.
