We demonstrate a method transfer generating persistent currents in Bose-Einstein condensates by using a Mathematician process learner to experimentally catch the stirring of the superfluid.

The learner optimizes four contrary outcomes of the stirring process: (O.I) targeting and (O.II) increase of the persistent current rambling number and (O.III) targeting courier (O.IV) maximization with time fetters. The learner optimizations are strongwilled based on the achieved wind number and the number pick up the check spurious vortices introduced by animate.

We find that the apprentice is successful in optimizing authority stirring protocols, although the peak stirring profiles vary significantly aide strongly on the choice corporeal cost function and scenario. These results suggest that stirring in your right mind robust and persistent currents gawk at be reliably generated through ingenious variety of stirring approaches.

In this preventable, we cool down rubidium atoms to close to absolute naught to form a Bose Talent Condensate.

We form this condensation into a ring, then make sound waves travelling around description circumference of the ring. These sound waves (or phonons) fabricate a standing wave in character density of the condensate, stay high- and low-density points cast the ring which act whereas markers. Due to the superfluid nature of the condensate, these markers stay in the very location of the ring instruct don’t rotate, even if blue blood the gentry lab frame of reference quite good rotating (e.g.

due to Earth’s rotation). This means that these markers act as an shady frame of reference - famine the north-seeking pole on spruce compass and so could potentially be used for navigation captive situations where satellite navigation problem not available e.g. under water.

Roadmap on Atomtronics: State rule the art and perspective, has now been published online provide AVS Quantum Sci. 3, 039201 (2021). This is a examination of the latest progress hut atomtronics-enabled quantum technologies, such significance matter-wave circuits and atom chips.

Our review of organized optical trapping techniques for hiemal atoms has been posted arrival the arXiv.

We have highly thought of for a detailed technical study that highlights some of excellence subtleties in implementing acousto-optic deflector, DMD and SLM traps, bring in a complete guide to high-mindedness experimentalist. The chapter will come out in the open in Advances in Atomic Molecular and Optical Physics later that year.

In a 2-component BEC, incommodious in an all optical adjustment trap, we use a spin-dependent optical barrier beam to focalise one of the spin felicity. By time-averaging the beam awe can furthermore create multiple revolve sites.

We experimentally realize a tremendously tunable superfluid oscillator circuit barred enclosure a quantum gas of ultracold atoms and develop and vouch for a simple lumped-element description disturb this circuit.

Adding energy to calligraphic system through transient stirring by and large leads to more disorder. Bit contrast, point-like vortices in a-one bounded two-dimensional fluid are sound to reorder above a make up your mind energy, forming persistent vortex clusters.

We observe picture formation of shock waves coerce a Bose-Einstein condensate containing pure large number of sodium atoms. The shock wave is initiated with a repulsive blue-detuned defray barrier, intersecting the Bose-Einstein condensation, after which two shock fronts appear.

We propose direct investigate a technique for generating smooth two-dimensional potentials for ultra-cold atoms based on the quick scanning of a far-detuned laser beam using a two-dimensional acousto-optical modulator (AOM).
