Narrow-line magneto-optical cooling and trapping of strongly magnetic atoms
Andrew J. Berglund, James L. Hanssen, Jabez J. McClelland
Laser cooling on weak transitions is a useful technique for reaching ultracold temperatures in atoms with multiple valence electrons. However, for strongly magnetic atoms a convent…
Sub-Doppler laser cooling and magnetic trapping of erbium
Andrew J. Berglund, Siu Au Lee, Jabez J. McClelland
We investigate cooling mechanisms in magneto-optically and magnetically trapped erbium. We find efficient sub-Doppler cooling in our trap, which can persist even in large magnetic…
Photon statistics and dynamics of Fluorescence Resonance Energy Transfer
Andrew J. Berglund, Andrew C. Doherty, Hideo Mabuchi
We report high time-resolution measurements of photon statistics from pairs of dye molecules coupled by fluorescence resonance energy transfer (FRET). In addition to quantum-optica…
Quantum coherence and control in one- and two-photon optical systems
Andrew J. Berglund
We investigate coherence in one- and two-photon optical systems, both theoretically and experimentally. In the first case, we develop the density operator representing a single pho…
Entangled state quantum cryptography: Eavesdropping on the Ekert protocol
D. S. Naik, C. G. Peterson, A. G. White +2
Using polarization-entangled photons from spontaneous parametric downconversion, we have implemented Ekert's quantum cryptography protocol. The near-perfect correlations of the pho…
