Long-range interaction of two metastable rare-gas atoms
Motivated by cold-collision studies of metastable rare-gas atoms @1–4# and prospects of achieving Bose-Einstein condensation in these systems @5#, we present calculations of long-range dispersion ~van der Waals! coefficients for two atoms interacting in the ns(3/2)2 atomic states (n53 for Ne, n54 for Ar, n55 for Kr, and n56 for Xe!. The metastable states have long lifetimes, 43 s for Xe @6#, de...
متن کاملFeasibility of Cooling and Trapping Metastable Alkaline-Earth Atoms
Metastability and long-range interactions of Mg, Ca, and Sr in the lowest-energy metastable P2 state are investigated. The calculated lifetimes are 38 min for Mg , 118 min for Ca , and 17 min for Sr , supporting feasibility of cooling and trapping experiments. The quadrupole-quadrupole long-range interactions of two metastable atoms are evaluated for various molecular symmetries. Hund’s case (c...
متن کاملUltracold collision properties of metastable alkaline-earth atoms.
Ultracold collisions of spin-polarized 24Mg, 40Ca, and 88Sr in the metastable 3P2 excited state are investigated based on molecular potentials obtained from ab initio calculations. We calculate the long-range interaction potentials and estimate the scattering length and the collisional loss rate as a function of magnetic field. The scattering lengths show resonance behavior due to the appearanc...
متن کاملQuantum computing with alkaline-Earth-metal atoms.
We present a complete scheme for quantum information processing using the unique features of alkaline-earth-metal atoms. We show how two completely independent lattices can be formed for the 1S0 and 3P0 states, with one used as a storage lattice for qubits encoded on the nuclear spin, and the other as a transport lattice to move qubits and perform gate operations. We discuss how the 3P2 level c...
متن کاملLong-range interactions of excited He atoms with the alkaline earth atoms Mg, Ca, and Sr.
Dispersion coefficients for the long-range interactions of the first four excited states of He, i.e., He(2 (1, 3)S) and He(2 (1, 3)P), with the low-lying states of the alkaline earth atoms Mg, Ca, and Sr are calculated by summing over the reduced matrix elements of multipole transition operators.
