“…It is estimated that the physical picture may be different from the results in this paper. In addition, it is known that vortices in BECs can be generated via an artificial magnetic field [39,40]. In this case, instead of following the axis of rotation, the vortex structures are modulated by the geometry of the magnetic field profiles.…”

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

“…Using inhomogeneous gauge potentials to induce local rotation into condensates holds the potential to be a valuable way to engineer and study interesting superfluid dynamics. These can range from the above study on phase separation in multicomponent condensates to creating well-defined initial states to study quantum turbulence [54]. The fact that such systems are experimentally possible using today's technology makes this an exciting and promising direction of research.…”

We study a twocomponent Bose-Einstein condensate in the presence of an inhomogeneous artificial gauge field. In response to this field, the condensate forms a localized vortex lattice structure that leads to a nontrivial symmetry breaking in the phase separated regime. The underlying physical mechanism can be understood by considering the energy landscape and we present a simplified model that is capable of reproducing the main features of the phase separation transition. The intuition gained by numerically solving this simplified model is then corroborated using an analytical solution found within the Thomas-Fermi limit.

“…These two domains have been mutually beneficial ever since the inception of ultracold matter. An example of such a hybridization can be found in the use of optical nanofibers surrounded by a cloud of cold atoms where the interaction between light and matter is facilitated by the evanescent field generated by the nanofiber [330][331][332][333] which can also be used to create spatially dependent artificial magnetic fields with new and exciting phenomena [334][335][336][337][338]. Here, one can use the phenomena produced in these dielectrics to affect ultracold atoms trapped in specific circuits that can be harnessed for quantum technologies, especially in sensing.…”

In this article, we provide perspectives for atomtronics circuits on quantum technology platforms beyond simple bosonic or fermionic cold atom matter-wave currents. Specifically, we consider (i) matter-wave schemes with multi-component quantum fluids; (ii) networks of Rydberg atoms that provide a radically new concept of atomtronics circuits in which the flow, rather than in terms of matter, occurs through excitations; (iii) hybrid matterwave circuits - a combination of ultracold atomtronic circuits with other quantum platforms that can lead to circuits beyond the standard solutions and provide new schemes for integrated matter-wave networks.We also sketch how driving these systems can open new pathways for atomtronics.
