Reduction of hydroxyl groups in optical nanofibers via in-fiber laser heating
Koki Oguri, Ken-ichi Harada, Samuel K. Ruddell +2
Optical nanofibers fabricated using a standard oxyhydrogen flame exhibit optical losses at wavelengths around 1385~nm due to absorption by embedded hydroxyl groups, posing a challe…
Fabrication of high-Q defect-free optical nanofiber photonic crystal resonators
Tomofumi Tanaka, Takahiro Suzuki, Owen Mao +3
We demonstrate the fabrication of defect-free optical-nanofiber photonic-crystal Fabry-Perot resonators with quality factors exceeding 10^7 using single-shot femtosecond laser abla…
Thermalization, condensate growth, and defect formation in an out-of-equilibrium Bose gas
D. J. Brown, A. V. H. McPhail, D. H. White +3
We experimentally and numerically investigate thermalization processes of a trapped Rb Bose gas, initially prepared in a non-equilibrium state through partial Bragg diffract…
Collective strong coupling of cold atoms to an all-fiber ring cavity
S. K. Ruddell, K. E. Webb, I. Herrera +2
We experimentally demonstrate a ring geometry all-fiber cavity system for cavity quantum electrodynamics with an ensemble of cold atoms. The fiber cavity contains a nanofiber secti…
Calorimetry of a harmonically trapped Bose gas
S. K. Ruddell, D. H. White, A. Ullah +2
We experimentally study the energy-temperature relationship of a harmonically trapped Bose-Einstein condensate by transferring a known quantity of energy to the condensate and meas…
Phase Noise in the Delta Kicked Rotor: From Quantum to Classical
D. H. White, S. K. Ruddell, M. D. Hoogerland
We experimentally investigate the effects of phase noise on the resonant and non-resonant dynamics of the atom-optics kicked rotor. Employing sinusoidal phase modulation at various…
Experimental Realization of a Quantum Ratchet Through Phase Modulation
D. H. White, S. K. Ruddell, M. D. Hoogerland
We report on an experimental realization of unidirectional transporting island structures in an otherwise chaotic phase space of the delta-kicked rotor system. Using a Bose-Einstei…
Quantum resonant effects in the delta-kicked rotor revisited
A. Ullah, S. K. Ruddell, J-A. Currivan +1
We review the theoretical model and experimental realization of the atom optics kicked rotor (AOKR), a paradigm of classical and quantum chaos. We have performed a number of ex…
