New limits on variation of the fine-structure constant using atomic dysprosium
N. Leefer, C. T. M. Weber, A. Cingöz +2
We report on the spectroscopy of radio-frequency transitions between nearly-degenerate, opposite-parity excited states in atomic dysprosium (Dy). Theoretical calculations predict t…
MW-Optical Double Resonance in Trapped Single Ion and its Application for Precision Experiments
S. Rahaman, J. Danielson, M. Schacht +3
We have employed the 12.6 GHz microwave transition resonance of a single trappedYb+ ion to accurately measure the size and relative orientation of the magnetic and optical…
Progress towards fabrication of Th:229-doped high energy band-gap crystals for use as a solid-state optical frequency reference
Wade G. Rellergert, Scott T. Sullivan, D. DeMille +5
We have recently described a novel method for the construction of a solid-state optical frequency reference based on doping Th into high energy band-gap crystals. Since nuc…
Quantum dense coding without entanglement
W. T. Buttler, S. K. Lamoreaux, J. R. Torgerson
We describe a quantum cryptography protocol with up to twenty four-dimensional () states generated by a polarization-, phase- and time-encoding transmitter. This pr…
Transverse laser cooling of a thermal atomic beam of dysprosium
N. Leefer, A. Cingöz, B. Gerber-Siff +3
A thermal atomic beam of dysprosium (Dy) atoms is cooled using the transition at 421 nm. The cooling is done via a standing light wave ort…
Transition frequency shifts with fine-structure constant variation for Yb II
S. G. Porsev, V. V. Flambaum, J. R. Torgerson
In this paper we report calculations of the relativistic corrections to transition frequencies (q factors) of Yb II for the transitions from the odd-parity states to the metastable…
