Isotope Shifts in the 7s8s Transition of Francium: Measurements and Comparison to \textit{ab initio} Theory
M. R. Kalita, J. A. Behr, A. Gorelov +10
We observe the electric-dipole forbidden transition in the francium isotopes Fr and Fr using a two-photon excitation scheme. We collect the at…
Matter, Energy, and Heat Transfer in a Classical Ballistic Atom Pump
Tommy A. Byrd, Kunal K. Das, Kevin A. Mitchell +2
A ballistic atom pump is a system containing two reservoirs of neutral atoms or molecules and a junction connecting them containing a localized time-varying potential. Atoms move t…
Ballistic atom pumps
Megan K. Ivory, Tommy A. Byrd, Andrew J. Pyle +4
We examine a classically-chaotic system consisting of two reservoirs of particles connected by a channel containing oscillating potential-energy barriers. We investigate whether su…
Offline trapping of Fr in a magneto-optical trap from implantation of an Ac ion beam
M. Tandecki, J. Zhang, S. Aubin +10
We demonstrate a new technique to prepare an offline source of francium for trapping in a magneto-optical trap. Implanting a radioactive beam of Ac, da…
Scattering by an oscillating barrier: quantum, classical, and semiclassical comparison
Tommy A. Byrd, Megan K. Ivory, Andrew J. Pyle +4
We present a detailed study of scattering by an amplitude-modulated potential barrier using three distinct physical frameworks: quantum, classical, and semiclassical. Classical phy…
Quantum Pumping with Ultracold Atoms on Microchips: Fermions versus Bosons
Kunal K. Das, Seth Aubin
We present a design for simulating quantum pumping of electrons in a mesoscopic circuit with ultra-cold atoms in a micro-magnetic chip trap. We calculate theoretical results for qu…
Fermions on atom chips
Marcius H. T. Extavour, Lindsay J. LeBlanc, Jason McKeever +5
We review our recent and ongoing work with Fermi gases on an atom chip. After reviewing some statistical and thermodynamic properties of the ideal, non-interacting Fermi gas, and a…
Measurement method for the nuclear anapole moment of laser trapped alkali atoms
E. Gomez, S. Aubin, G. D. Sprouse +2
Weak interactions within a nucleus generate a nuclear spin dependent parity violating electromagnetic moment; the anapole moment. In heavy nuclei, the anapole moment is the dominan…
Lifetime and hyperfine splitting measurements on the 7s and 6p levels in rubidium
E. Gomez, S. Aubin, L. A. Orozco +1
We present lifetime measurements of the 7S1/2 level and the 6p manifold of rubidium. We use a timecorrelated single-photon counting technique on a sample of 85Rb atoms confined and…
A single hollow beam optical trap for cold atoms
S. Kulin, S. Aubin, S. Christe +3
We present an optical trap for atoms that we have developed for precision spectroscopy measurements. Cold atoms are captured in a dark region of space inside a blue-detuned hollow…
Surface Phonons and Other Localized Excitations
Philip B. Allen, Seth Aubin, R. B. Doak
The diatomic linear chain of masses coupled by harmonic springs is a textboook model for vibrational normal modes (phonons) in crystals. In addition to propagating acoustic and opt…
