Rydberg atoms offer strong and controllable atomic interactions that can be tuned by selecting states with different principal quantum number or orbital angular momentum. In addition, Rydberg atoms present long lifetimes and many available energy levels. Their energy state separations allow coupling to electromagnetic fields from Megahertz to Terahertz range. Such features make them highl…
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…
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…
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…

Experiments involving Rydberg atoms strongly depend on lasers in the 480-510 nm range of the visible spectrum. This is generally achieved through frequency doubling in nonlinear crystals within optical cavities, using low-power amplified diode lasers. However, stabilizing these cavities can be complex, depending on various parameters. Currently, there are bulk doubling crystals that allow…
Experiments with Rydberg atoms rely significantly on lasers with a highly stabilized frequency. The most effective way to achieve this stabilization is through frequency locking in optical cavities with high stability. These cavities are kept temperature stable and vacuum isolated. The objective of this project is to assemble an optical cavity capable of stabilizing three different wavele…

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…

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…
