Observation of cold collisions between trapped ions and trapped atoms.
نویسندگان
چکیده
We study cold collisions between trapped ions and trapped atoms in the semiclassical (Langevin) regime. Using Yb+ ions confined in a Paul trap and Yb atoms in a magneto-optical trap, we investigate charge-exchange collisions of several isotopes over three decades of collision energies down to 3 mueV (k_{B}x35 mK). The minimum measured rate coefficient of 6x10;{-10} cm;{3} s;{-1} is in good agreement with that derived from a Langevin model for an atomic polarizability of 143 a.u.

Spontaneous evolution of rydberg atoms into an ultracold plasma
We have observed the spontaneous evolution of a dense sample of Rydberg atoms into an ultracold plasma, in spite of the fact that each of the atoms may initially be bound by up to 100 cm(-1). When the atoms are initially bound by 70 cm(-1), this evolution occurs when most of the atoms are translationally cold, <1 mK, but a small fraction, approximately 1%, is at room temperature. Ionizing colli...

During the pa;t few years there has been an enormous progress in the use of light to manipulate the translational degr:es of freedom of atoms. Laser light resonant with an atornic transition has been used to slowl, coo12 and ti.ap3 neutral atorns. An intense effort is now being carritsd out with the purpose of using laser radiation techniques t o improve methods of atomic manipulation in order ...
متن کاملTheories for cold atomic collisions in light fields
I describe the current theories for cold collisions between laser-cooled and trapped neutral atoms in light fields. The emphasis is on the dynamical nature of the problem, i.e. on the collisional loss of atoms from the trap or collisional heating of the atomic cloud. The recent work on optical shielding of collisions is also reviewed.
متن کاملInelastic collisions in optically trapped ultracold metastable ytterbium.
We report measurement of inelastic loss in dense and cold metastable ytterbium (Yb[3P2]). Use of an optical far-off-resonance trap enables us to trap atoms in all magnetic sublevels, removing m-changing collisional trap loss from the system. Trapped samples of Yb[3P2] are produced at a density of 2 x 10(13) cm(-3) and temperature of 2 microK. We observe rapid two-body trap loss of Yb[3P2] and m...
متن کاملBlue-sky bifurcation of ion energies and the limits of neutral-gas sympathetic cooling of trapped ions
Sympathetic cooling of trapped ions through collisions with neutral buffer gases is critical to a variety of modern scientific fields, including fundamental chemistry, mass spectrometry, nuclear and particle physics, and atomic and molecular physics. Despite its widespread use over four decades, there remain open questions regarding its fundamental limitations. To probe these limits, here we ex...
