A new form of liquid matter: Quantum droplets

ZH Luo, W Pang, B Liu, YY Li, BA Malomed - Frontiers of Physics, 2021 - Springer
This brief review summarizes recent theoretical and experimental results which predict and
establish the existence of quantum droplets (QDs), ie, robust two-and three-dimensional (2D …

New states of matter with fine-tuned interactions: quantum droplets and dipolar supersolids

F Böttcher, JN Schmidt, J Hertkorn… - Reports on Progress …, 2020 - iopscience.iop.org
Quantum fluctuations can stabilize Bose–Einstein condensates (BEC) against the mean-
field collapse. Stabilization of the condensate has been observed in quantum degenerate …

Pattern formation in quantum ferrofluids: From supersolids to superglasses

J Hertkorn, JN Schmidt, M Guo, F Böttcher, KSH Ng… - Physical Review …, 2021 - APS

systems. In equilibrium, quantum ferrofluids formed from ultracold atoms were recently …

Developments in atomic control using ultracold magnetic lanthanides

MA Norcia, F Ferlaino - Nature Physics, 2021 - nature.com
Lanthanide atoms have an unusual electron configuration, with a partially filled shell of f
orbitals. This leads to a set of characteristic properties, including large numbers of optical …

Self-bound dipolar droplets and supersolids in molecular Bose-Einstein condensates

M Schmidt, L Lassablière, G Quéméner, T Langen - Physical Review Research, 2022 - APS
We numerically study the many-body physics of molecular Bose-Einstein condensates with
strong dipole-dipole interactions. We observe the formation of self-bound droplets, and …

Roton excitations in an oblate dipolar quantum gas

JN Schmidt, J Hertkorn, M Guo, F Böttcher, M Schmidt… - Physical Review Letters, 2021 - APS
We observe signatures of radial and angular roton excitations around a droplet
crystallization transition in dipolar Bose-Einstein condensates. In situ measurements are …

Rotating a supersolid dipolar gas

SM Roccuzzo, A Gallemí, A Recati, S Stringari - Physical review letters, 2020 - APS
Distinctive features of supersolids show up in their rotational properties. We calculate the
moment of inertia of a harmonically trapped dipolar Bose-Einstein condensed gas as a …

Long-lifetime supersolid in a two-component dipolar Bose-Einstein condensate

S Li, UN Le, H Saito - Physical Review A, 2022 - APS
