1. Visualizing edge states with an atomic Bose gas in the quantum Hall regime
Topic: Physics
Published: 5/19/2016
Authors: Ian B Spielman, Ben Stuhl, Hsin I Lu, Lauren Moise Aycock, Dina Genkina
Abstract: We engineered a two-dimensional magnetic lattice in an elongated strip geometry, with effective per-plaquette flux $\approx4/3$ times the flux quanta. We imaged the localized edge and bulk states of atomic Bose-Einstein condensates in this strip ...

2. Magnetic phases of spin-1 spin‹orbit-coupled Bose gases
Topic: Physics
Published: 5/1/2016
Authors: Ian B Spielman, Daniel Campbell, Ryan Price, Ana Valdes-Curiel, Andika Putra, Dimitrius Trypogeorgos
Abstract: Phases of matter are characterized by order parameters describing the type and degree of order in a system. Here we experimentally explore the magnetic phases present in a near-zero temperature spin-1 spin‹orbit-coupled atomic Bose gas and the qu ...

3. EUV-induced oxidation of carbon on TiO2
Topic: Physics
Published: 3/25/2016
Authors: Nadir S Faradzhev, Shannon Bradley Hill
Abstract: Previously we reported on the etch rates of C on TiO2 by oxidizers including NO, O3 and H2O2 when irradiated by extreme ultraviolet (EUV) radiation at 13.5 nm [Faradzhev et al., J.Phys. Chem. C, 117 (2013) 23072‹23081]. We demonstrated that the i ...

4. High-contrast and fast electrochromic switching enabled by plasmonics
Topic: Physics
Published: 1/27/2016
Authors: Ting Xu, Erich C. Walter, Amit Kumar Agrawal, Christopher C. Bohn, Jeyavel Velmurugan, Wenqi Zhu, Henri J Lezec, Albert A. Talin
Abstract: With vibrant colours and simple, room-temperature processing methods, electrochromic polymers have attracted attention as active materials for flexible, low-power-consuming devices. However, slow switching speeds in devices realized to date, as well ...

5. Spectrum and Energy Levels of Five-Times Ionized Zirconium (Zr VI)
Topic: Physics
Published: 1/5/2016
Authors: Joseph Reader, Mark D. Lindsay
Abstract: The spectrum of five-times-ionized zirconium Zr VI was observed from 160 Å to 2000 Å with sliding spark discharges on 10.7-m normal- and grazing-incidence spectrographs. The existing analysis of this spectrum [Khan Z. A. et al. 1985 Phys. Scr. 31 83 ...

6. Direct observation of Feshbach enhanced s-wave scattering of fermions
Topic: Physics
Published: 12/17/2015
Authors: Dina Genkina, Lauren Moise Aycock, Hsin I Lu, Ian B Spielman, Benjamin K. Stuhl
Abstract: We directly measured the s-wave scattering cross-section of ultracold 40K atoms across the 20.2 mT Feshbach resonance by colliding pairs of degenerate Fermi gases (DFGs) and imaging the scattered atoms. Owing to DFG‰s low density, few atoms scatt ...

7. A strong loophole-free test of local realism
Topic: Physics
Published: 12/16/2015
Authors: Lynden Krister Shalm, Evan Meyer-Scott, B. G. Christensen, Peter LaBonne Bierhorst, Michael Alan Wayne, Deny Hamel, Martin J Stevens, Thomas Gerrits, Scott C Glancy, Michael Shane Allman, Kevin J Coakley, Shellee Dawn Dyer, Adriana E Lita, Varun Boehm Verma, Joshua C Bienfang, Alan L Migdall, Yanbao Zhang, William Farr, Francesco Marsili, Matthew D. Shaw, Jeffrey Stern, Carlos Abellan, Waldimar Amaya, Valerio Pruneri, Thomas Jennewein, Morgan Mitchell, P. G. Kwiat, Richard P Mirin, Emanuel H Knill
Abstract: We present a loophole-free violation of local realism using entangled photon pairs. We ensure that all relevant events in our Bell test are spacelike separated by placing the parties far enough apart and by using fast random number generators and hig ...

8. Accurate multiconfiguration calculations of energy levels, lifetimes and transition rates for the silicon isoelectronic sequence: Ti IX - Ge XIX, Sr XXV, Zr XXVII, Mo XXIX
Topic: Physics
Published: 12/6/2015
Authors: P. Jonsson, L Radziute, G. Gaigalas, M. Godefroid, J P Marques, T Brage, Charlotte Fischer, I. P. Grant
Abstract: Multiconfiguration Dirac-Hartree-Fock (MCDHF) calculations and relativistic configuration interaction (RCI) calculations are performed for states of the 3s23p2, 3s3p3 and 3s23p3d configurations in the Si-like ions Ti IX - Ge XIX, Sr XXV, Zr XXVII, M ...

9. Adapting the Poisson-Influenced K-Means Algorithm for a Larger User Base
Topic: Physics
Published: 11/19/2015
Authors: Brian P. Morris, Zachary H Levine
Abstract: A superconducting transition edge sensor (TES) can be a useful tool for counting the number of photons in a highly attenuated pulse of light, but it requires calibration for its outputs to be interpretable as photon numbers. The Poisson-Influenced K- ...

10. Radiative damping in wave guide based FMR measured via analysis of perpendicular standing spin waves in sputtered Permalloy films
Topic: Physics
Published: 11/17/2015
Authors: Thomas J Silva, Justin M Shaw, Hans Toya Nembach, Mathias Weiler, Martin Schoen
Abstract: The damping α of the spinwave resonances in 75 nm, 120 nm, and 200 nm -thick Permalloy films is measured via vector-network- analyzer ferromagnetic-resonance (VNA-FMR). Inductive coupling between the sample and the waveguide leads to an addi ...
