The exit velocity of a compressed air cannon
Z. J. Rohrbach, T. R. Buresh, M. J. Madsen
The use of compressed air cannons in an undergraduate lab provides a way to illustrate the cooperation of diverse physics concepts, such as conservation of momentum, the work-kinet…
Compact Toroidal Ion Trap Design and Optimization
M. J. Madsen, C. H. Gorman
We present the design of a new type of compact toroidal, or "halo", ion trap. Such traps may be useful for mass spectrometry, studying small Coulomb cluster rings, quantum informat…
Angular Normal Modes of a Circular Coulomb Cluster
L. W. Lupinski, M. J. Madsen
We investigate the angular normal modes for small oscillations about an equilibrium of a single-component coulomb cluster confined by a radially symmetric external potential to a c…
Measuring the Molecular Polarizability of Air
M. J. Madsen, D. R. Brown, S. R. Krutz +1
We present an update of the "refractive index of air" experiment commonly used in optics and undergraduate advanced labs. The refractive index of air is based on the average molecu…
Efficient Photoionization-Loading of Trapped Cadmium Ions with Ultrafast Pulses
L. Deslauriers, M. Acton, B. B. Blinov +16
Atomic cadmium ions are loaded into radiofrequency ion traps by photoionization of atoms in a cadmium vapor with ultrafast laser pulses. The photoionization is driven through an in…
Ultrafast Coherent Coupling of Atomic Hyperfine and Photon Frequency Qubits
M. J. Madsen, D. L. Moehring, P. Maunz +3
We demonstrate ultrafast coherent coupling between an atomic qubit stored in a single trapped cadmium ion and a photonic qubit represented by two resolved frequencies of a photon.…
