Ultracold 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...

15 صفحه اولFeasibility 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 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 کامل4 D ec 2 00 3 Properties of metastable alkaline - earth - metal atoms calculated using an accurate effective core potential
The first three electronically excited states in the alkaline-earth-metal atoms magnesium, calcium, and strontium comprise the (nsnp) P o J (J = 0, 1, 2) fine-structure manifold. All three states are metastable and are of interest for optical atomic clocks as well as for cold-collision physics. An efficient technique—based on a physically motivated potential that models the presence of the ioni...
