Blackbody radiation shift in 87Rb frequency standard
M. S. Safronova, Dansha Jiang, U. I. Safronova
The operation of atomic clocks is generally carried out at room temperature, whereas the definition of the second refers to the clock transition in an atom at absolute zero. This i…
Interactions Between Rydberg-Dressed Atoms
J. E. Johnson, S. L. Rolston
We examine interactions between atoms continuously and coherently driven between the ground state and a Rydberg state, producing "Rydberg-dressed atoms." Because of the large dipol…
Ultrafast Gates for Single Atomic Qubits
W. C. Campbell, J. Mizrahi, Q. Quraishi +6
We demonstrate single qubit operations on a trapped atom hyperfine qubit using a single ultrafast pulse from a mode-locked laser. We shape the pulse from the laser and perform a pi…
State-insensitive bichromatic optical trapping
Bindiya Arora, M. S. Safronova, Charles W. Clark
We propose a scheme for state-insensitive trapping of neutral atoms by using light with two independent wavelengths. In particular, we describe the use of trapping and control lase…
Universal rates for reactive ultracold polar molecules in reduced dimensions
Andrea Micheli, Zbigniew Idziaszek, Guido Pupillo +3
Analytic expressions describe universal elastic and reactive rates of quasi-two-dimensional and quasi-one-dimensional collisions of highly reactive ultracold molecules interacting…
Theory and applications of atomic and ionic polarizabilities
J. Mitroy, M. S. Safronova, Charles W. Clark
Atomic polarization phenomena impinge upon a number of areas and processes in physics. The dielectric constant and refractive index of any gas are examples of macroscopic propertie…
