Particle-imbalanced weakly interacting quantum droplets in one dimension

IA Englezos, P Schmelcher, SI Mistakidis - Physical Review A, 2024 - APS
We explore the formation of one-dimensional two-component quantum droplets with
intercomponent particle imbalance using an ab initio many-body method. It is shown that for …

Droplets and supersolids in ultra-cold atomic quantum gases

K Mukherjee, TA Cardinale, L Chergui… - The European Physical …, 2023 - Springer
In this mini-review, we briefly summarize some of the main concepts and ideas behind
highly dilute self-bound quantum droplets of both binary and dipolar character. The latter …

Comparison of renormalized interactions using one-dimensional few-body systems as a testbed

F Brauneis, HW Hammer, SM Reimann, AG Volosniev - Physical Review A, 2025 - APS
Even though the one-dimensional contact interaction requires no regularization,
renormalization methods have been shown to improve the convergence of numerical …

Two-component droplet phases and their stability in one dimension

EG Charalampidis, SI Mistakidis - arxiv preprint arxiv:2409.19852, 2024 - arxiv.org
We unravel the existence and stability properties of one-dimensional droplets arising in
genuine two-component particle imbalanced bosonic mixtures under the influence of a weak …

Two-component droplet phases and their spectral stability in one dimension

EG Charalampidis, SI Mistakidis - Physical Review A, 2025 - APS
We unravel the existence and stability properties of one-dimensional droplets arising in

Yrast states of quantum droplets confined in a ring potential

M Ögren, GM Kavoulakis - Physical Review A, 2025 - APS
We consider a quantum droplet which is confined in a ring potential. We investigate the so-
called yrast state, ie, the lowest-energy state of the droplet assuming that it has some fixed …

Instability and particle-current control of a parametrically driven Bose-Einstein condensate in a ring-shaped lattice

LQ Lai - Physical Review A, 2025 - APS
We investigate the dynamics of a Bose-Einstein condensate in a one-dimensional ring-
shaped lattice with the Peierls phase and site-dependent modulations, where the …

Two-dimensional bosonic droplets in a harmonic trap

F Brauneis, AG Volosniev, HW Hammer - arxiv preprint arxiv:2410.00570, 2024 - arxiv.org
We investigate a system of bosons in a two-dimensional harmonic trap. In the limit of strong
attractive interactions, the bosons make a droplet insensitive to external confinement. For …

Quantum correlations and spatial localization in trapped one-dimensional ultra-cold Bose-Bose-Bose mixtures

TD Anh-Tai, MA García-March, T Busch… - arxiv preprint arxiv …, 2025 - arxiv.org
We systematically investigate and illustrate the complete ground-state phase diagram for a
one-dimensional, three-species mixture of a few repulsively interacting bosons trapped …

From spontaneous to explicit symmetry breaking in a finite-sized system: Bosonic bound states of an impurity

L Chergui, F Brauneis, TA Cardinale… - arxiv preprint arxiv …, 2024 - arxiv.org
The presence of a single attractive impurity in an ultracold repulsive bosonic system can
drive a transition from a homogeneous to a localized state, as we here show for a one …
