Three-level Haldane-like model on a dice optical lattice

September 21, 2015
Author(s)
Ian B. Spielman, T. Andrijauskas, E. Anisimovas, M. Raciunas, A. Mekys, V. Kudriasov, G. Juzeliunas
We consider ultracold atoms in a two-dimensional optical lattice of the dice geometry in a tight-binding regime. The atoms experience a laser-assisted tunneling between the nearest neighbor sites of the dice lattice accompanied by the momentum recoil. This

Coulomb bound states of strongly interacting photons

Author(s)
Mohammad F. Maghrebi, Michael Gullans, Przemek Bienias, Soonwon Choi, Ivar Martin, Ofer Firstenberg, Mikhail D. Lukin, Hans Peter Buchler, Alexey Gorshkov
We show that two photons coupled to Rydberg states via electromagnetically induced transparency can interact via an effective Coulomb potential. This interaction gives rise to a continuum of two-body bound states. Within the continuum, metastable bound

Assessing the Thermal Protective Performance of Fire Blocking Barrier Fabrics for Residential Upholstered Furniture: Report to Consumer Product Safety Commission for Interagency Agreement CPSC-I-13-0022

September 17, 2015
Author(s)
Shonali Nazare, John R. Shields, Szabolcs Matko, Rick D. Davis
Fire behavior of five barrier fabrics has been evaluated both, as an individual component and as a part of composite samples, using different test methods. The quantitative component test methods selected to characterize fire behavior of barrier fabrics

Creating Nanostructured Superconductors by Local Current Annealing

Hongwoo H. Baek, Jeonghoon Ha, Duming Zhang, Bharath NMN Natarajan, Jonathan P. Winterstein, Renu Sharma, Rongwei Hu, Kefeng Wang, Steven Ziemak, Johnpierre Paglione, Young Kuk, Nikolai B. Zhitenev, Joseph A. Stroscio
Superconductivity results from a Bose condensate of Cooper-paired electrons with a macroscopic quantum wavefunction. Dramatic effects can occur when the region of the condensate is shaped and confined to the nanometer scale. Recent progress in

We report a two-detector measurement of the propagation speed of neutrinos over a baseline of 734 km. The measurement was made with the NuMI beam at Fermilab between the near and far MINOS detectors. The fractional difference between the neutrino speed and

Structural origins of enhanced capacity retention in novel copolymerized sulfur-based composite cathodes for high-energy density Li-S batteries

September 17, 2015
Author(s)
Vladimir P. Oleshko, Jenny J. Kim, Jennifer L. Schaefer, Steven D. Hudson, Christopher L. Soles, Adam Simmonds, Jared Griebel, Kookheon Char, Jeff Pyun
Poly(sulfur-random-(1,3-diisopropenylbenzene) (poly(S-r-DIB)) copolymers synthesized via inverse vulcanization form high molecular mass electrochemically active polymers capable of realizing enhanced capacity retention (1005 mAh/g at 100 cycles) and

Using mixtures of biological samples as genome-scale process controls

September 17, 2015
Author(s)
Jerod R. Parsons, Patrick S. Pine, Marc L. Salit, Sarah A. Munro, Jennifer H. McDaniel
Background: Genome-scale “-omics” measurements are challenging to benchmark, due to the enormous number of individual measurands. Mixtures of previously-characterized samples can be used to benchmark repeat performance using mixture proportions as truth

When does a branched polymer becomes a particle?

September 17, 2015
Author(s)
Alexandros Chremos, Jack F. Douglas
Melts with topologically distinct molecular structures are investigated by molecular dynamics simulation. We determine the mean polymer size and shape, and glass transition temperature for each molecular topology. Both in terms of structure and dynamics

Edward Sisco, Jessica L. Staymates, Katherine Schilling, John Gillen
The development of a chemically relevant artificial fingerprint material as well as a preliminary method for fingerprint deposition is discussed herein. More specifically the improvement of an artificial sweat material, an artificial sebaceous material
