Is Quantum Cryptography Provably Secure?

Author(s)
Anastase Nakassis, Joshua C. Bienfang, Paul M. Johnson, Alan Mink, D J. Rogers, Xiao Tang, Carl J. Williams
Quantum cryptography asserts that shared secrets can be established over public channels in such a way that the total information of an eavesdropper can be made...

Topological Insulators and Metals in Atomic Optical Lattices

Author(s)
Tudor Stanescu, Victor Galitski, Jay Vaishnav, Charles W. Clark, Sankar Das Sarma
We propose the realization of topological quantum states with cold atoms trapped in an optical lattice. We discuss an experimental setup that generates a two...

Understanding Insecure IT: Practical Risk Assessment

Author(s)
Simon Liu, D. Richard Kuhn, Hart Rossman
IT systems have long been at risk from vulnerable software, malicious actions, or inadvertent user errors, in addition to run-of-the-mill natural and human-made...

A deep-UV optical frequency comb at 205 nm

Author(s)
Scott A. Diddams, E Peters, P Fendel, S Reinhardt, T W. Hansch, T Udem
By frequency quadrupling a picosecond pulse train from a Ti:sapphire laser at 820 nm we generate a frequency comb at 205 nm with nearly bandwidth-limited pulses...

Carbon Nanomaterials Standards Efforts at NIST

Author(s)
Jeffrey A. Fagan
Development of carbon nano-materials for applications has been hindered to date by a lack of standard protocols, i.e. documentary standards, and physical...

Capillary Instability in Nanoimprinted Polymer Films

Author(s)
Kyle J. Alvine, Yifu Ding, Hyun Wook Ro, Brian C. Okerberg, Alamgir Karim, Christopher L. Soles, Jack F. Douglas
Capillary forces play an active role in defining the equilibrium structure of nanoscale structures. This effect can be especially pronounced in soft materials...

Observing the Quantization of Zero Mass Carriers in Graphene

Author(s)
Joseph A. Stroscio, Gregory M. Rutter, D. L. Miller, K. Kubista, W. A. de Heer, Phillip N. First
Application of a magnetic field to conductors causes the charge carriers to circulate in cyclotron orbits with quantized energies called Landau levels (LLs)...

SERS not to be taken for granted in the presence of oxygen

Author(s)
Melek Erol, Yun Han, Scott K. Stanley, Christopher Stafford, Henry Du, Svetlana Sukhishvili
In this communication, we report that oxidation of the Ag nanoparticle (Ag NP) surface under ambient conditions has a dramatic effect on the adsorption and SERS...

Time domain measurement of phase noise in a spin torque oscillator

Author(s)
Mark W. Keller, Anthony B. Kos, Thomas J. Silva, William H. Rippard, Matthew R. Pufall
We measure phase noise from the zero crossings of the voltage vs. time waveform of a spin torque nanocontact oscillating in a vortex mode. The power spectrum of...

Linking Air and Vacuum Mass Measurement by Magnetic Levitation

Author(s)
Zeina J. Kubarych, Patrick J. Abbott, Edwin R. Williams, Ruimin Liu, Vincent J. Lee, Hung-Kung Liu
This paper describes a new approach to directly link air and vacuum mass measurements using magnetic levitation techniques. This procedure provides direct...
