Abstract:

Um estudo das taxas de perda de átomos ocorrendo numa armadilha magneto-óptica mista foi realizado aqui. Observamos experimentalmente, pela primeira vez, a ocorrência de processos colisionais inelásticos envolvendo duas espécies atômicas distintas. Identificamos o escape radiativo como o processo dominante nas taxas de perda de átomos da armadilha de sódio, devidas às colisões desses com os átomos de rubídio aprisionados, para as dadas condições experimentais. Realizamos estudos semelhantes com uma mistura K-Rb, onde as taxas de perda de átomos da armadilha de potássio foram observadas. Procurou-se interpretar os resultados através um modelo semiclássico que teve de ser modificado por nós. Esses estudos foram importantes porque revelaram a grande influência do processo de escape radiativo nas taxas de perda. Também verificou-se que outros canais podem manifestar a sua influência e suspeitamos que isso se deva às diferenças estruturais das \"quasimoléculas\" formadas na colisão. A compreensão de processos colisionais em armadilhas magneto-ópticas mistas é importante para a obtenção e estudo de amostras distintas de condensados bosônicos coexistindo numa mesma região.
We report the results of the trap-Ioss collisional rates observed in a mixed species magneto-optical trapo These are the first systematic studies about the collisionalloss channels due to heteronuclear interactions between two cold atomic sampIes in aMOr. We have used two different combinations: Na-Rb and K -Rb. lt was observed that the rates are strongly affected by the radiative escape Ioss channel, especially in the Na-Rb system. We also observed that some other Ioss channels may ruIe the rates behavior depending on the combination or the experimento To understand the results a semiclassical approach was used: the Gallagher-Prichard theory. We beIieve that these studies will soon be helpful to control the interatomic collisional rates for the achievement of heteronuclear sampIes of Bose-Einstein condensates.

Abstract:

Neste trabalho, abordamos dois assuntos independentes e interessantes que permeiam o cotidiano dos pesquisadores da área de resfriamento e confinamento de átomos neutros. O primeiro está relacionado aos processos de perda de átomos ocorrendo em armadilhas magneto-ópticas, a partir das quais o fenômeno é observado. Mostramos que a conjunção de dois modelos tradicionais da literatura é capaz de gerar um modelo semiclássico e semi-analítico básico e robusto, capaz de reproduzir as características fundamentais dos resultados experimentais já obtidos, incluindo os mais recentes. Isto demonstra que os aspectos essenciais dos mecanismos de perda em armadilhas são, agora, bem compreendidos. O segundo assunto abordado aqui está relacionado à observação de moléculas diatômicas formadas em armadilhas magneto-ópticas. Nesse sentido, uma série de experimentos básicos foi realizada, gerando resultados e discussões que constituem uma rica fonte de informação inspirando a continuação e conclusão do trabalho iniciado aqui, cujo objetivo final é a caracterização precisa e o desenvolvimento técnicas de resfriamento e aprisionamento de moléculas diatômicas heteronucleares.
We report the results concerning to two main subjects of laser cooling and trapping community. We begin by presenting the results of modeling two-body trap loss rates as a function of the trap laser intensity. We show that one can merge two simple theories to obtain a semiclassical and semi-analytical model which is able to provide the fundamental properties observed in the experimental results found in the literature. Hence, we concluded that the essential features of the two-body trap loss rates taking place in MOTs are now well understood. On the other hand, we run a set of experiments trying to produce and detect heteronuclear diatomic ultracold molecules. Although this has not been accomplished yet, we have acquired a wide and rich amount of data that will certainly be very helpful for continuing and concluding the work here started. In the near future the photoassociation spectroscopy of ultracold heteronuclear diatomic molecules will provide valuable information to help in its manipulation.

The magneto-optical traps cool and trap atoms in a given region, forming clouds of cold atoms. As the setting of the trap, clouds can be obtained in different geometries such as spherical or ring-shaped. Traps have a wide range of applications, such as building atomic clocks, to obtain the Bose-Einstein condensate and the study of collisions, wherein the ring geometry is interesting to study in low dimensions. The learning of the trap parameters implies in its characterization and thus the appropriate parameters allow to optimize the trap and improve the performance of it s. The objective of our work is to study the behavior of the motion of atoms and the forces that act upon them by varying some parameters of the trap, such as the magnetic field gradient, the detuning between the laser frequency and the atomic transition, the intensity of the laser beams and also the intensity beams profile of the beams. By using the integration method of Runge-Kutta, we present simulations of the trajectory of a trapped atom and the radius of the orbit varying the same parameters of the trap mentioned above. One can find in literature a description of the force exertd on the trapped atoms with Gaussian profile laser beams in the traditional configuration and also with a small misalignment. From the deduction of the force on the trapped atoms with laser beams of Gaussian profile, we present some considerations to find the force acting on the atoms with Gaussian beam profile and simulations in this new configuration. Thus, the possibility of trapping atoms with other intensity beam profiles can be tested.
As armadilhas magneto-ópticas resfriam e aprisionam átomos em uma determinada região, formando nuvens de átomos frios. Conforme a configuração da armadilha, pode-se obter nuvens em diferentes geometrias, como esféricas ou em forma de anel. As armadilhas tem uma grande gama de aplicações, como a construção de relógios atômicos, a obtenção do condensado de Bose-Einstein e o estudo de colisões, no qual a geometria em anel se torna interessante para o estudo em baixas dimensões. Para conhecer os parâmetros da armadilha é necessário fazer sua caracterização. Parâmetros adequados permitem otimizar a armadilha e melhorar a performance da mesma. O objetivo de nosso trabalho é estudar o comportamento do movimento dos átomos e das forças que atuam sobre eles ao variar alguns parâmetros da armadilha, como por exemplo o gradiente de campo magnético, a dessintonia entre a frequência do laser e da transição atômica, a intensidade dos feixes laser e o perfil de intensidade dos feixes. Utilizando o método de integração de Runge- Kutta, apresentaremos simulações da trajetória de um átomo aprisionado e o raio da órbita variando os mesmos parâmetros da armadilha anteriormente citados. Na literatura encontra-se a descrição da força exercida sobre os átomos aprisionados com feixes laser de perfil gaussiano na configuração tradicional e também com um pequeno desalinhamento. A partir da dedução da força sobre os átomos aprisionados com feixes laser de perfil gaussiano, apresentaremos algumas considerações feitas para encontrar a força que atua sobre os átomos com feixes de perfil não gaussiano e simulações realizadas nesta nova consideração. Desta forma, poderá se verificar se existe a possibilidade de aprisionar átomos com feixes de outros perfis de intensidade.

Abstract:

It has been more than 30 years since the first demonstration of a magneto-optical trap (MOT) using sodium atoms. Since then the MOT has revolutionised the field of atomic physics by facilitating the emergence of a broad range of productive avenues of research using atoms prepared at low temperatures and high densities. This thesis describes the development of a novel kind of magneto-optical trap: the blue-detuned MOT. Unlike in all previous MOTs the light is blue detuned from atomic resonances and drives "type-II" transitions that have dark ground-state sub-levels. A discussion of the position-dependent and velocity-dependent forces experienced by an atom or molecule in a MOT is first used to consolidate recent theoretical work and, in particular, to introduce the concept of a blue-detuned MOT. The design and construction of an experiment that has been built to demonstrate a blue-detuned MOT using ⁸⁷Rb is described. A thorough characterisation of this novel MOT has been performed. At high magnetic field gradients, radiation-pressure-limited densities exceeding 10¹¹ cm⁻³ have been reached whilst temperatures are cooled below 30μK by the efficient and robust sub-Doppler cooling mechanisms. The maximum phase-space density measured is 6 x 10⁻⁶, which is higher than in most normal atomic MOTs, comparable to the best dark SPOTs, and a million times higher than that reported for red-detuned type-II MOTs. This makes the blue-detuned MOT particularly attractive for molecules where laser cooling and trapping always uses type-II transitions. For the first time, a study of trap loss due to ultra-cold collisions between atoms occurring in the presence of near-resonant blue-detuned light is undertaken. Finally, the experiment is used to demonstrate many new and unreported configurations of MOT for ⁸⁷Rb, showing that a comprehensive understanding of complicated MOTs is now possible, and presenting a clear direction for further research.

Abstract:

We Rydberg dress a magneto-optical trap of strontium atoms, mixing Rydberg character into atoms as they are cooled and confined. A recently developed tunable high-power narrow-linewidth 319 nm laser is used to excite and characterise triplet Rydberg states in strontium. Off-resonantly dressing a cloud of atoms in a narrow-line MOT operating on the 5s2 1S0 - 5s5p 3P1 transition, we observe a one-body AC Stark shift on the cloud, which we characterise to identify a regime in which only Rydberg dressed atoms are trapped in the MOT. In this cloud the Rydberg dressed atoms are both trapped and cooled. Increasing atomic density in the dressed MOT, plasma formation is observed at densities lower than the density necessary for observation of Rydberg dressed atoms. This plasma is caused by a build-up of charges due to spontaneous ionisation of Rydberg atoms, which then DC Stark shift the Rydberg state onto resonance with the coupling laser. The high charge density of the plasma then results in strong Rydberg excitation that causes rapid depletion of atoms. Regimes using optimum Rydberg states and charge-extracting electric fields are identified that may prevent plasma formation, and allow the interacting regime to be reached. Such a regime, with cooling, confinement, and tunable interactions, may form the basis of a quantum simulator for dissipative many-body systems.
