Bose-Einstein condensation of ultracold atomic gases
نویسندگان
چکیده
Bose-Einstein condensation in a dilute gas of sodium atoms has been observed. The atoms were trapped in an optically plugged magnetic trap or in a cloverleaf magnetic trap. Rf induced evaporative cooling increased the phase-space density by six orders of magnitude. We summarize the different techniques used, and discuss recent studies of properties of Bose condensates with an outlook on future developments. PACS: 03.75.Fi, 05.30.Jp, 32.80.Pj, 64.60.-

Molecular Bose-Einstein condensation in a versatile low power crossed dipole trap
We produce Bose-Einstein condensates of 6Li2 molecules in a low power (22W) crossed optical dipole trap. Fermionic Li atoms are collected in a magnetooptical trap from a Zeeman slowed atomic beam, then loaded into the optical dipole trap where they are evaporatively cooled to quantum degeneracy. Our simplified system offers a high degree of flexibility in trapping geometry for studying ultracol...
متن کاملStochastic Optimization of Bose-Einstein Condensation Using a Genetic Algorithm
In 1924/25, Satyendranath Bose and Albert Einstein predicted that particles of integer spin (today called bosons) should undergo a quantum statistical phase transition when cooled to temperatures very close to absolute zero (Bose, 1924; Einstein, 1925). This phenomenon, nowadays called Bose-Einstein condensation, has been experimentally observed seventy years later using ultracold (nanokelvin t...
متن کاملBCS-BEC Crossover: From High Temperature Superconductors to Ultracold Superfluids
We review the BCS to Bose Einstein condensation (BEC) crossover scenario which is based on the well known crossover generalization of the BCS ground state wavefunction Ψ0. While this ground state has been summarized extensively in the literature, this Review is devoted to less widely discussed issues: understanding the effects of finite temperature, primarily below Tc, in a manner consistent wi...

We summarize all experimental studies of Bose-Einstein condensation (BEC) in dilute atomic gases reported thus far and discuss the experimental techniques used to produce, manipulate and observe nanokelvin samples of atoms.
متن کاملMolecule formation in ultracold atomic gases
This review describes recent experimental and theoretical advances in forming molecules in ultracold gases of trapped alkali metal atoms, both by magnetic tuning through Feshbach resonances and by photoassociation. Molecular Bose-Einstein condensation of long-range states of both boson dimers and fermion dimers was achieved in 2002-3. Condensates of boson dimers were found to be short-lived, bu...
