Rydberg atoms are extremely sensitive to microwave electromagnetic fields. In this project, we propose to build a magneto-optical trap inside a microwave cavity where Rydberg atoms will be excited. This will allow us to investigate: i) the influence of the microwave cavity on the lifetime of Rydberg states; ii) accurately measure microwave fields through induced electromagnetic transparen…
The research field of ultracold (T<<1mK) molecules is continuously expanding in many directions, involving an increasing number of groups throughout the world. Molecules at ultracold temperatures move at very small velocities and thus can be precisely controlled in their quantum state. Unfortunately, until recently, laser cooling could not be applied easily to molecules because they gener…
Experiments involving cold Rydberg atoms and Ccld molecules rely heavily on highly frequency-stabilized lasers. The most appropriate way to implement this is by locking the frequency in highly stabilized optical cavities. Such cavities are stabilized at temperature and isolated in vacuum. Currently, the main manufacturer of these cavities charges values between 40-50 thousand dollars for …
In recent years, our laboratory completely dominated the technique of optical traps dipole. Currently, we produce on a daily basis trapped samples of one or two atomic species, using lasers or 1.6 microns and at 10.6 microns. Such samples have generally 10e6 trapped atoms in densities of 10e12 and átomos/cm3 temperatures less than 20 ¼K. Currently, this sample is trapped the starting poin…
This project is based on current work taking place in the research group of Professor Luis Marcassa at the University of São Paulo (USP) and Prof. James Shaffer at the University of Oklahoma (OU). Experiments on Rydberg atom- Rydberg atom interactions will be conducted to study their anisotropy using novel Rydberg atom imaging and time-of-flight methods. The results of these experiments w…

In recent years, our laboratory has completely mastered the dipole optic trap technique. Currently, we produce daily trapped samples of one or two atomic species using a high power laser at 1.06 ¼m. Such samples generally have 10 6 atoms trapped at densities of 10 12 atoms / cm 3 and temperatures less than 20 ¼K. Today, this trapped sample is the starting point for any modern experiment i…

Samples of cold Rydberg atoms have been proposed as ideal systems to perform quantum computing. This is because these atoms have ultra-long range interactions. Making use of this interaction, several theoretical proposals utilize the internal states of these atoms to generate entanglement, and thus create the qubit. Of course, some interactions between a few atoms or higher order interact…
The Atomic Interactions Laboratory (LIA) has been conducting research on atoms trapped for more than a decade. During this period, we specialize in cold Rydberg atoms and cold molecules in optical dipole traps. Obtaining such samples takes several different experimental techniques for the control and handling thereof. One involves controlling the intensity and spatial shape of light beams…

Rydberg interactions have been guiding the recent researches, leading to an accelerated development of areas like quantum computation and matter-field interactions. A new technique that has been used for the detection of Rydberg atoms uses images that are the result of a direct projection of the atomic spatial distribution. This image is obtained after the ionization of the Rydberg atoms …
The production of citrus destined for processing is dominated worldwide by Florida and Sao Paulo. In these two locations diseases cause severe economic losses. In a recent paper by our group in collaboration with the group of Prof.. Ehsani became clear that there are spectral differences between the Brazilian and American samples. The objective of this stage is to collect images of Americ…
The production of bosonic condensate and its use in several experiments can be very complex. The new alternative is its production in a chamber, that it contains the magnets and laser beams, and after that its transport for another one, where the experiment will be carried out. In this project we will use the technique of optical twizers for the transport of a condensate to the second cha…
