Steady-state microwave mode cooling with a diamond NV ensemble
Donald P. Fahey, Kurt Jacobs, Matthew J Turner +4
A fundamental result of quantum mechanics is that the fluctuations of a bosonic field are given by its temperature . An electromagnetic mode with frequency in the microwave…
A Polariton-Stabilized Spin Clock
Matthew E. Trusheim, Kurt Jacobs, Jonathan E. Hoffman +3
Atom-like quantum systems in solids have been proposed as a compact alternative for atomic clocks, but realizing the potential of solid-state technology will requires an architectu…
Optical Nanofibers: a new platform for quantum optics
Pablo Solano, Jeffrey A. Grover, Jonathan E. Hoffman +4
The development of optical nanofibers (ONF) and the study and control of their optical properties when coupling atoms to their electromagnetic modes has opened new possibilities fo…
Near-field measurement of modal interference in optical nanofibers for sub-Angstrom radius sensitivity
Fredrik K. Fatemi, Jonathan E. Hoffman, Pablo Solano +4
Optical nanofibers (ONF) of subwavelength dimensions confine light in modes with a strong evanescent field that can trap, probe, and manipulate nearby quantum systems. To measure t…
Rayleigh scattering in an optical nanofiber as a probe of higher-order mode propagation
Jonathan E. Hoffman, Fredrik K. Fatemi, Guy Beadie +2
Optical nanofibers provide a rich platform for exploring atomic and optical phenomena even when they support only a single spatial mode. Nanofibers supporting higher-order modes pr…
Inhomogeneous broadening of optical transitions of 87Rb atoms in an optical nanofiber trap
J. Lee, J. A. Grover, J. E. Hoffman +2
We experimentally demonstrate optical trapping of 87Rb atoms using a two-color evanescent field around an optical nanofiber. In our trapping geometry, a blue-detuned traveling wave…
Ultrahigh Transmission Optical Nanofibers
J. E. Hoffman, S. Ravets, J. A. Grover +5
We present a procedure for reproducibly fabricating ultrahigh transmission optical nanofibers (530 nm diameter and 84 mm stretch) with single-mode transmissions of 99.95 0.0…
Intermodal Energy Transfer in a Tapered Optical Fiber: Optimizing Transmission
S. Ravets, J. E. Hoffman, P. R. Kordell +3
We present an experimental and theoretical study of the energy transfer between modes during the tapering process of an optical nanofiber through spectrogram analysis. The results…
A low-loss photonic silica nanofiber for higher-order modes
S. Ravets, J. E. Hoffman, L. A. Orozco +3
Optical nanofibers confine light to subwavelength scales, and are of interest for the design, integration, and interconnection of nanophotonic devices. Here we demonstrate high tra…
Thin-film superconducting resonator tunable to the ground-state hyperfine splitting of Rb
Z. Kim, C. P. Vlahacos, J. E. Hoffman +13
We describe a thin-film superconducting Nb microwave resonator, tunable to within 0.3 ppm of the hyperfine splitting of Rb at GHz. We coarsely tuned the re…
Atoms Talking to SQUIDs
J. E. Hoffman, J. A. Grover, Z. Kim +10
We present a scheme to couple trapped Rb atoms to a superconducting flux qubit through a magnetic dipole transition. We plan to trap atoms on the evanescent wave outside an…
Superradiance of cold atoms coupled to a superconducting circuit
Daniel Braun, Jonathan Hoffman, Eite Tiesinga
We investigate superradiance of an ensemble of atoms coupled to an integrated superconducting LC-circuit. Particular attention is paid to the effect of inhomogeneous coupling const…
