“…[39,44] for more details. The condensate is possibly inhomogeneous as discussed in [49]. We note that the condition Ω ⩽ 1/R ≪ √ eB is implicitly assumed: the first inequality is due to the causality, and the second one is to make the Landau quantization sensible [32].…”

“…Under large rotation, the system becomes highly inhomogeneous. This could for example yield the situation that a vortex structure with the condensate could locate only at the region very close to boundary [49]. Since it is quite nontrivial to incorporate such inhomogeneous configuration in our Ginzburg-Landau analysis, we will leave it for future study.…”

We revisit the condensation scenario of charged pions in external magnetic field and rotation, which was first considered by Y. Liu and I. Zahed. Based on the Ginzburg-Landau analysis of the Nambu-Jona-Lasinio model, we find that the charged-pion condensation takes place only when both a strong coupling constant and negatively large baryon chemical potential are applied. Besides, our numerical calculation shows that the chiral restoration induced by the interplay between magnetic field and rotation (i.e., the rotational magnetic inhibition) interrupts the formation of the charged-pion condensate. This suggests that the analysis of such condensation requires a careful treatment of the inner structure of pions, which was not taken into account before. We also discuss the underlying physical mechanism of our finding and the indication of charged-rho condensation.

“…Since then quantum droplets have been realized with dipolar systems made of 164 Dy [19][20][21][22]24], 162 Dy [25] and 166 Er [23] atoms. Bose-Bose droplets were first observed in mixtures of different spin states of 39 K [26-28, 30, 31], and subsequently also in different heteronuclear mixtures of 41 K- 87 Rb [29,85] and 23 Na- 87 Rb [86].…”

“…The self-bound nature of these quantum droplets has been experimentally demonstrated in dipolar systems with 164 Dy [22] and 162 Dy [25], in homonuclear Bose-Bose mixtures of different spin states in 39 K [26,27], and in heteronuclear mixtures of 41 K-87 Rb [29, 85] and 23 Na- 87 Rb [86]. Example images of self-bound droplets and expanding BECs for different expansion times are shown in figures 2(a) and (b) for the dipolar system and the Bose mixture, respectively.…”

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

Quantum fluctuations can stabilize Bose–Einstein condensates (BEC) against the mean-field collapse. Stabilization of the condensate has been observed in quantum degenerate Bose–Bose mixtures and dipolar BECs. The fine-tuning of the interatomic interactions can lead to the emergence of two new states of matter: liquid-like self-bound quantum droplets and supersolid crystals formed from these droplets. We review the properties of these exotic states of matter and summarize the experimental progress made using dipolar quantum gases and Bose–Bose mixtures. We conclude with an outline of important open questions that could be addressed in the future.

In this article, we study the vortex formation in spin-1 spin-orbit coupling rotating Bose-Einstein condensates. Numerical results are obtained by solving the spinor Gross-Pitaevskii equation. We mainly focus on the influences of external magnetic fields on vortex structures and dynamics properties. With the increase in magnetic field strength, the populations of magnetic components j = ±1 reach the identical value. For the density profile, the three components present identical density structures, and the size of condensates is nearly the same. In addition, some related physical quantities, such as the time taken for the arrival of a steady population and root-mean-square size, kinetic energy, and total angular momentum, are calculated. The results show that these quantities decrease as the magnetic field strength increases. Moreover, we also investigate the time evolution of angular momentum. It is seen that the dynamic behavior of the magnetic components j = ±1 is exactly consistent, and the total angular momentum reduces in the presence of the strong magnetic field. This reflects the fact that the introduction of the strong magnetic field makes it difficult to rotate the condensate, and thus, it is disadvantageous for generating more vortices. topics: vortex, spin-orbit coupled, magnetic field, spinor condensates
