The Infrared Spectrum of NN...CO+ Trapped in Solid Neon

Author(s)
Warren E. Thompson, Marilyn E. Jacox
Codeposition of a Ne:N2:CO = 200:1:1 mixture at 4.3 K with a beam of very pure neon atoms excited to their energy levels between 16.6 and 16.85 eV leads to...

Trapped-Ion State Detection through Coherent Motion

Author(s)
Till P. Rosenband, David Hume, Chin-Wen Chou, David R. Leibrandt, Michael J. Thorpe, David J. Wineland
Coherent control of trapped atomic ions has led to several recent advances in quantum information processing 1 and precision spectroscopy 2. A basic requirement...

Neutron scattering experiments on a polycrystalline sample of the frustrated pyrochlore magnet Tb 2Ti 2O 7, which does not show any magnetic order down to 50 mK...

Mechanism for puddle formation in graphene

Author(s)
Shaffique Adam, Suyong S. Jung, Nikolai N. Klimov, Nikolai B. Zhitenev, Joseph A. Stroscio, Mark D. Stiles
Close to charge neutrality, graphene's energy landscape is highly inhomogeneous, forming a sea of electron-like and hole-like puddles that determine the...

On-chip, photon-number-resolving, telecommunication-band detectors for scalable photonic information processing

Author(s)
Thomas Gerrits, Nick Thomas-Peter, James Gates, Adriana E. Lita, Benjamin Metcalf, Brice R. Calkins, Nathan A. Tomlin, Anna E. Fox, Antia A. Lamas-Linares, Justin Spring, Nathan Langford, Richard P. Mirin, Peter Smith, Ian Walmsley, Sae Woo Nam
Integration is currently the only feasible route towards scalable photonic quantum processing devices which are sufficiently complex to be genuinely useful in...

Common Origin of the Two Types of Magnetic Fluctuations in Iron Chalcogenides

Author(s)
Songxue Chi, Jose Rodriguez Rivera, Jeffrey W. Lynn, Chenglin Zhang, D. Phelan, Deepak Singh, Rick L. Paul, Pengcheng Dai
We use inelastic neutron scattering to study the low energy spin excitations in moderately doped non-superconducting Fe 1.01Te 0.72Se 0.28. The spin excitations...
