Observation of quantum droplets in a heteronuclear bosonic mixture

C D'Errico, A Burchianti, M Prevedelli, L Salasnich… - Physical Review …, 2019 - APS
We report on the formation of heteronuclear quantum droplets in an attractive bosonic
mixture of K 41 and Rb 87. We observe long-lived self-bound states, both in free space and …

Collisions of self-bound quantum droplets

G Ferioli, G Semeghini, L Masi, G Giusti, G Modugno… - Physical review …, 2019 - APS
We report on the study of binary collisions between quantum droplets formed by an attractive
mixture of ultracold atoms. We distinguish two main outcomes of the collision, ie, merging …

Lee-Huang-Yang effects in the ultracold mixture of and with attractive interspecies interactions

Z Guo, F Jia, L Li, Y Ma, JM Hutson, X Cui… - Physical Review …, 2021 - APS
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 …

Two-dimensional vortex quantum droplets

Y Li, Z Chen, Z Luo, C Huang, H Tan, W Pang… - Physical Review A, 2018 - APS
It was recently found that the Lee-Huang-Yang (LHY) correction to the mean-field
Hamiltonian of binary atomic boson condensates suppresses the collapse and creates …

Observation of a lee-huang-yang fluid

TG Skov, MG Skou, NB Jørgensen, JJ Arlt - Physical Review Letters, 2021 - APS
We observe monopole oscillations in a mixture of Bose-Einstein condensates, where the
usually dominant mean-field interactions are canceled. In this case, the system is governed …

Modulational instability, inter-component asymmetry, and formation of quantum droplets in one-dimensional binary Bose gases

T Mithun, A Maluckov, K Kasamatsu, BA Malomed… - Symmetry, 2020 - mdpi.com
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 …

Vortex lattices in strongly confined quantum droplets

TA Yoğurt, U Tanyeri, A Keleş, MÖ Oktel - Physical Review A, 2023 - APS
Bose mixture quantum droplets display a fascinating stability that relies on quantum
fluctuations to prevent collapse driven by mean-field effects. Most droplet research focuses …

Correlated dynamics of collective droplet excitations in a one-dimensional harmonic trap

IA Englezos, SI Mistakidis, P Schmelcher - Physical Review A, 2023 - APS
We address the existence and dynamics of one-dimensional harmonically confined
quantum droplets appearing in two-component mixtures by deploying a nonperturbative …
