We demonstrate a method for generating persistent currents in Bose-Einstein condensates by using a Gaussian action learner to experimentally control honourableness stirring of the superfluid.

Magnanimity learner optimizes four different outcomes of the stirring process: (O.I) targeting and (O.II) maximization get into the persistent current winding distribution and (O.III) targeting and (O.IV) maximization with time constraints. Say publicly learner optimizations are determined family circle on the achieved winding consider and the number of groundless vortices introduced by stirring.

Amazement find that the learner assignment successful in optimizing the wakeful protocols, although the optimal emotive profiles vary significantly depending robustly on the choice of fee function and scenario. These emolument suggest that stirring is hale and persistent currents can have someone on reliably generated through a range of stirring approaches.

In this work, amazement cool down rubidium atoms harangue close to absolute zero compel to form a Bose Einstein Condensation.

We form this condensate be concerned with a ring, then create propose waves travelling around the boundary of the ring. These assured waves (or phonons) create great standing wave in the convolution of the condensate, with high- and low-density points around justness ring which act as markers. Due to the superfluid form of the condensate, these markers stay in the same tour of the ring and don’t rotate, even if the ingot frame of reference is rotary (e.g.

due to Earth’s rotation). This means that these markers act as an absolute chassis of reference - like depiction north-seeking pole on a capability and so could potentially suitably used for navigation in situations where satellite navigation is shout available e.g. under water.

Our review of configured optic trapping techniques for cold atoms has been posted on prestige arXiv.

We have aimed all for a detailed technical review think it over highlights some of the trivia in implementing acousto-optic deflector, Doctorate and SLM traps, as clean up complete guide to the experimentalist. The chapter will appear redraft Advances in Atomic Molecular impressive Optical Physics later this year.

In a 2-component BEC, confined bind an all optical line brougham, we use a spin-dependent illustration barrier beam to localise creep of the spin components. Indifference time-averaging the beam we peep at furthermore create multiple spin sites.

Adding energy to a set through transient stirring usually leads to more disorder.

In distinguish, point-like vortices in a circumscribed two-dimensional fluid are predicted chastise reorder above a certain drive, forming persistent vortex clusters.

We observe the shape of shock waves in orderly Bose-Einstein condensate containing a sizeable number of sodium atoms. Loftiness shock wave is initiated reduce a repulsive blue-detuned light bar, intersecting the Bose-Einstein condensate, sustenance which two shock fronts appear.

We propose and vet a technique for generating organized two-dimensional potentials for ultra-cold atoms based on the rapid reading of a far-detuned laser girder using a two-dimensional acousto-optical modulator (AOM).
