Atomic physics on a 50-nm scale: Realization of a bilayer system of dipolar atoms

L Du, P Barral, M Cantara, J de Hond, YK Lu… - Science, 2024 - science.org
Controlling ultracold atoms with laser light has greatly advanced quantum science. The
wavelength of light sets a typical length scale for most experiments to the order of 500 …

Droplets of trapped quantum dipolar bosons

A Macia, J Sánchez-Baena, J Boronat, F Mazzanti - Physical review letters, 2016 - APS
Strongly interacting systems of dipolar bosons in three dimensions confined by harmonic
traps are analyzed using the exact path integral ground-state Monte Carlo method. By …

Dipolar Bose supersolid stripes

R Bombin, J Boronat, F Mazzanti - Physical review letters, 2017 - APS
We study the superfluid properties of a system of fully polarized dipolar bosons moving in
the XY plane. We focus on the general case where the polarization field forms an arbitrary …

Andreev–Bashkin effect in superfluid cold gases mixtures

J Nespolo, GE Astrakharchik, A Recati - New Journal of Physics, 2017 - iopscience.iop.org
We study a mixture of two superfluids with density–density and current–current (Andreev–
Bashkin) interspecies interactions. The Andreev–Bashkin coupling gives rise to a …

Bloch oscillations and matter-wave localization of a dipolar quantum gas in a one-dimensional lattice

G Natale, T Bland, S Gschwendtner… - Communications …, 2022 - nature.com
Three-dimensional quantum gases of strongly dipolar atoms can undergo a crossover from
a dilute gas to a dense macrodroplet, stabilized by quantum fluctuations. Adding a one …

Real-time dynamics and proposal for feasible experiments of lattice gauge–Higgs model simulated by cold atoms

Y Kuno, K Kasamatsu, Y Takahashi… - New Journal of …, 2015 - iopscience.iop.org
Lattice gauge theory has provided a crucial non-perturbative method in studying canonical
models in high-energy physics such as quantum chromodynamics. Among other models of …

Collective interlayer pairing and pair superfluidity in vertically stacked layers of dipolar excitons

M Zimmerman, R Rapaport… - Proceedings of the …, 2022 - National Acad Sciences
Layered bosonic dipolar fluids have been suggested to host a condensate of interlayer
molecular bound states. However, experimental observation has remained elusive …

Attractive and repulsive dipolar interaction in bilayers of indirect excitons

DJ Choksy, C Xu, MM Fogler, LV Butov, J Norman… - Physical Review B, 2021 - APS
We explore attractive dipolar interaction in indirect excitons (IXs). For one layer of IXs in a
single pair of coupled quantum wells (CQWs), the out-of-plane IX electric dipoles lead to …

Two-dimensional bright solitons in dipolar Bose-Einstein condensates with tilted dipoles

The effect of dipolar orientation with respect to the soliton plane on the physics of two-
dimensional bright solitons in dipolar Bose-Einstein condensates is discussed. Previous …

Synthetic dimensions in the strong-coupling limit: Supersolids and pair superfluids

T Bilitewski, NR Cooper - Physical Review A, 2016 - APS
We study the many-body phases of bosonic atoms with N internal states confined to a one-
dimensional (1D) optical lattice under the influence of a synthetic magnetic field and strong …
