The physics of dipolar bosonic quantum gases
This paper reviews the recent theoretical and experimental advances in the study of ultra-cold gases made of bosonic particles interacting via the long-range, anisotropic dipole–dipole interaction,
Plasmonic analogue of electromagnetically induced transparency at the Drude damping limit.
TLDR
A nanoplasmonic analogue of EIT is experimentally demonstrated using a stacked optical metamaterial to achieve a very narrow transparency window with high modulation depth owing to nearly complete suppression of radiative losses.
Bose-Einstein condensation of chromium.
We report on the generation of a Bose-Einstein condensate in a gas of chromium atoms, which have an exceptionally large magnetic dipole moment and therefore underlie anisotropic long-range
Stabilization of a purely dipolar quantum gas against collapse
For the first time, a purely dipolar quantum gas has been prepared experimentally. Different regimes have been explored; in some, the gas is stable, whereas in others it collapses due to the strong
Tuning the dipolar interaction in quantum gases.
TLDR
It is shown that even the very weak magnetic dipole coupling in alkali gases can be used to excite collective modes and tuned from positive to negative values and even switched off completely by fast rotation of the orientation of the dipoles.
Microwave electrometry with Rydberg atoms in a vapour cell using bright atomic resonances
Atoms can be used as highly sensitive magnetic-field sensors. By exploiting the effects of electric fields on the optical transitions of excited Rydberg states, it is now demonstrated that it is also
d-wave collapse and explosion of a dipolar bose-einstein condensate.
TLDR
Good agreement is found between the experimental results and those of a numerical simulation of the three-dimensional Gross-Pitaevskii equation, including contact and dipolar interactions as well as three-body losses about the collapse of a dipolar condensate.
Observation of Quantum Droplets in a Strongly Dipolar Bose Gas.
TLDR
By systematic measurements on individual droplets it is demonstrated quantitatively that quantum fluctuations mechanically stabilize them against the mean-field collapse, and the interference of several droplets indicating that this stable many-body state is phase coherent.
Observation of dipole-dipole interaction in a degenerate quantum gas.
TLDR
The measurements are consistent with the theory of dipolar quantum gases and show that a chromium condensate is an excellent model system to study dipolar interactions in such gases.
Bose-Einstein condensation with magnetic dipole-dipole forces
Since the advent of Bose-Einstein condensation in dilute gases of alkali metals @1# and hydrogen @2#, it has become apparent that the interactions between the condensed atoms govern most of the
