Families of Elliptic Curves with Rational 3-torsion

Author(s)
Dustin Moody, Hongfeng Wu
In this paper we look at three families of elliptic curves with rational 3-torsion over a finite field. These families include Hessian curves, twisted Hessian

Probing the timescale of the exchange interaction in a ferromagnetic alloy

Author(s)
Justin M. Shaw, Stefan Mathias, Chan La-O-Vorakiat, Hans T. Nembach, Thomas J. Silva, Mark Siemens, Henry Kapteyn, Margaret Murnane
The underlying physics of all ferromagnetic behavior is the cooperative interaction between individual atomic magnetic moments that results in a macroscopic

Optimization of the TES-bias circuit for a multiplexed microcalorimeter array

Author(s)
William B. Doriese, Bradley K. Alpert, Joseph W. Fowler, Gene C. Hilton, Alex S. Hojem, Kent D. Irwin, Carl D. Reintsema, Daniel R. Schmidt, Greg Stiehl, Daniel S. Swetz, Joel N. Ullom, Leila R. Vale
In the detector-bias circuit of a transition-edge-sensor (TES) microcalorimeter, the TES-shunt resistor (Rsh) and the thermal conductance to the cryogenic bath

DNA Molecules Descending a Nanofluidic Staircase by Entropophoresis

Author(s)
Samuel M. Stavis, Jon C. Geist, Michael Gaitan, Laurie E. Locascio, Elizabeth A. Strychalski
A complex entropy gradient for confined DNA molecules was engineered for the first time. Following the second law of thermodynamics, this enabled the directed

Spin transport in memristive devices

Author(s)
Hyuk-Jae Jang, Oleg A. Kirillov, Oana Jurchescu, Curt A. Richter
We report on electron spin transport through electrochemically precipitated copper filaments formed in TaOX memristive devices consisting of Co(60nm)/TaOX(16nm)

Contrast variation in spin-echo small angle neutron scattering

Author(s)
Xin Li, Bin Wu, Yun Liu, Roger Pynn, Chwen-Yang Shew, Gregory S. Smith, Kenneth W. Herwig, J. Lee Robertson, Wei-Ren Chen, Li Liu
The use of contrast variation in spin-echo small angle neutron scattering (SESANS) experiments is discussed for the case of colloidal structural investigation

Efficiency of quasiparticle evacuation in superconducting devices

Author(s)
Sukumar Rajauria, L. Pascal, P. Gandit, F. Hekking, B. Pannetier, H. Courtois
We have studied the di®usion of excess quasiparticles in a current-biased superconductor strip in proximity to a metallic trap junction. In particular, we have

Ultrafast Demagnetization Measurements using Extreme Ultraviolet Light: Comparison of Electronic and Magnetic Contributions

Author(s)
Thomas J. Silva, Justin M. Shaw, Hans T. Nembach, Margaret M. Murnane, Henry C. Kapteyn, Chan La-O-Vorakiat, Stefan Mathias, Emrah Turgut, Teale A. Carson, Martin Aeschlimann, Claus M. Schneider
Ultrashort pulses of extreme ultraviolet light from high-harmonic generation are a new tool for probing coupled charge, spin, and phonon dynamics with element

Standards for the Optical Detection of Protein Particulates

Author(s)
Dean C. Ripple, Michael J. Carrier, Joshua R. Wayment
Particulates in protein therapeutics, composed of agglomerated protein monomers, may cause an immunogenic response in patients. Consequently, industry and the

Beyond s-wave scattering for ultracold atoms

Author(s)
Ross A. Williams, Lindsay J. LeBlanc, Karina K. Jimenez Garcia, Matthew C. Beeler, Abigail R. Perry, William D. Phillips, Ian B. Spielman
Interactions between particles can be strongly altered by their environment. Here we demonstrate a technique for modifying interactions between ultracold atoms

Internal Curing - Constructing More Robust Concrete

Author(s)
Jason Weiss, Dale P. Bentz, Anton Schlinder, Pietro Lura
It is often said that there are two types of concrete: concrete that has cracked and concrete that is going to crack. Unfortunately, this is true all too
