Chern Numbers Hiding in Time-of-Flight Images

Author(s)
Ian B. Spielman, Erhai Zhao, Noah Bray-Ali, Carl J. Williams, Indubala Satija
We present a novel technique for detecting topological invariants -- Chern numbers -- from time-of-flight images of ultra-cold neutral atoms. The Chern number

Electrolyte stability determines scaling limits for solid-state 3D Li-ion batteries

Dmitry A. Ruzmetov, Vladimir P. Oleshko, Paul M. Haney, Henri J. Lezec, K Karki, K Baloch, Amit K. Agrawal, Albert Davydov, Sergiy Krylyuk, Y Liu, JY Huang, Mihaela M. Tanase, John Cumings, Albert A. Talin
Rechargeable, all-solid state Li-ion batteries (LIBs) with high specific capacity and small footprint are highly desirable to power an emerging class of

Counting the Leaves of Trees

Author(s)
Brian D. Cloteaux, Luis A. Valentin
A number of important combinatorial counting problems can be reformulated into the problem of counting the number of leaf nodes on a tree. Since the basic leaf

Higher-order photon correlations in pulsed photonic crystal nanolasers

Author(s)
D. Elvira, X. Hachair, Varun Verma, R. Braive, G. Beaudoin, I. Robert-Philip, I. Sagnes, Burm Baek, Sae Woo Nam, E Dauler, I. Abram, Martin Stevens, A. Beveratos
We report on the higher-order photon correlations of a high-Β nanolaser under pulsed excitation at room temperature. Using a multiplexed four-element

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
