Perspectives for a new realization of the pascal by optical methods

October 24, 2017
Author(s)
Jay H. Hendricks, Karl Jousten, Jack A. Stone Jr., Patrick F. Egan, Tom Rubin, Christof Gaiser, Rene Schodel, James A. Fedchak, Jacob E. Ricker, Jens Fluegge, Stephen P. Eckel, Julia K. Scherschligt, Daniel S. Barker, Kevin O. Douglass, Gregory F. Strouse, Uwe Sterr, Waldimir Sabuga
Since the beginning of measurement of pressure in the 17th century, the unit of pressure has been defined by the relationship of force per unit area. The present state of optical technology now offers the possibility of using a thermodynamic definition

How Large Can We Go? Isolation of > 1 nm Diameter Single-Wall Carbon Nanotubes Species using Aqueous Two Phase Extraction

April 14, 2015
Author(s)
Jeffrey A. Fagan, Erik Haroz, Rachelle Ihly, Hui Gui, Jeffrey Blackburn, Jeffrey R. Simpson, Stephen K. Doorn, Stephanie Lam, Angela R. Hight Walker, Ming Zheng
We demonstrate the effective separation of near-monochiral single-wall carbon nanotube (SWCNT) species with diameters > 1 nm through multi-stage aqueous two phase extraction (ATPE), and report an empirical function for the surfactant concentrations at

Detection of l-C3H+ in Sgr B2(N) and Sgr B2(OH) and Refinement of its Spectroscopic Constants via the Publicly Available PRIMOS Survey and the Barry E. Turner Legacy Survey

September 1, 2013
Author(s)
Francis J. Lovas, Brett A. McGuire, P. B. Carroll, Ryan A. Loomis, Geoffery A. Blake, Jan M. Hollis, Phillip R. Jewell, Anthony J. Remijan
Pety et al. (2012) recently reported the detection and assignment of l-C3H+ in the Horsehead nebula. Here, we expand that analysis to include the J = 1 - 0 and J = 2 - 1 transitions of l-C3H+ observed in absorption towards Sgr B2(N) in data from the

Stimulated Generation of Superluminal Light Pulses via Four-wave Mixing

April 26, 2012
Author(s)
Ryan T. Glasser, Ulrich Vogl, Paul D. Lett
We report on the four-wave mixing of superluminal pulses, in which both the injected and generated pulses involved in the process propagate with negative group velocities. Generated pulses with negative group velocities of up to vg = −c/880 are
