Materials Research Science and Engineering Centers
Materials Research Science and Engineering Centers Interdisciplinary materials research and education addressing fundamental problems in science and engineering that are important to society Materials Research Science and Engineering Centers are supported by the The National National Science Foundation (NSF) to undertake materials research of scope and Science complexity that would not be feasible under traditional funding of individual Foundation research projects. Materials Research THESE CENTERS: Science & ♦ require outstanding research quality, intellectual breadth, interdisciplinarity, flexibility Engineering in responding to new research opportunities, support for research infrastructure, and Centers foster the integration of research and education in the materials field; Program was established in ♦ address fundamental, complex problems of intellectual and societal importance, 1994. ♦ contribute to national priorities by fostering active collaboration between academia and other sectors, and ♦ constitute a national network of university-based Centers in materials research. Center Characteristics The MRSECs constitute a spectrum of coordinated Centers of differing scientific breadth and administrative complexity that may address any area (or several areas) of materials research. ♦ Each MRSEC encompasses one or more Interdisciplinary Research Groups (IRGs). ♦ Each IRG involves a group of faculty members, associated researchers and students addressing a major topic in materials research. ♦ In each IRG, sustained support for interactive effort by several participants with complementary backgrounds, skills, and knowledge is critical to progress. 1 Each MRSEC also incorporates most or all of the following activities to an extent commensurate with the size of the Center: ♦ Programs to stimulate interdisciplinary education, including research experiences for undergraduates accessible to students from other institutions, and the development of human resources (including support for under-represented groups). -

CARBON NANOTUBE TRANSISTORS: CAPACITANCE MEASUREMENTS, LOCALIZED DAMAGE, AND USE AS GOLD SCAFFOLDING A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Luke Anthony Kaiser Donev May 2009 °c 2009 Luke Anthony Kaiser Donev ALL RIGHTS RESERVED CARBON NANOTUBE TRANSISTORS: CAPACITANCE MEASUREMENTS, LOCALIZED DAMAGE, AND USE AS GOLD SCAFFOLDING Luke Anthony Kaiser Donev, Ph.D. Cornell University 2009 Carbon nanotubes are incredible materials with interesting mechanical and elec- trical properties. This thesis presents diverse experiments based on carbon nan- otube transistors. We measured the capacitance of individual carbon nanotubes. The density of states of a carbon nanotube will influence the tube’s capacitance. We report good agreement with theory and that we successfully probe the tube’s density of states. We show it is possible to open holes into the carbon nanotubes without com- pletely destroying the conductance of the tube. The application of localized damage to nanotube transistors opens up several exciting potential device ge- ometries. We also present several experiments where carbon nanotubes are used as nanoscale scaffolding for the deposition and manipulation of gold. Nanometer scale balls of gold are deposited on nanotubes from an atomic force microscope. Nanotubes are also used to influence gold wires undergoing electromigration. This thesis demonstrates just some of many novel techniques being applied to carbon nanotubes, and lays groundwork for the exciting applications nan- otubes will help realize. BIOGRAPHICAL SKETCH Luke Anthony Kaiser Donev was born on August 19, 1979 in Toronto, Canada. He was greeted by his parents Mary and Stef and brother Jason. -
Double Diffractive Higgs and Di-Photon Production at The
MAN/HEP/2001/03 MC-TH-01/09 October 2001 Double Diffractive Higgs and Di-photon Production at the Tevatron and LHC Brian Cox and Jeff Forshaw Dept. of Physics and Astronomy, University of Manchester Manchester M13 9PL, England [email protected] Beate Heinemann Oliver Lodge Laboratory, University of Liverpool Liverpool, L69 7ZE, England [email protected] Abstract We use the POMWIG Monte Carlo generator to predict the cross-sections for double diffractive higgs and di-photon production at the Tevatron and LHC. We find that the higgs production cross-section is too small to be observable at Tevatron energies, and even at arXiv:hep-ph/0110173v2 13 Oct 2001 the LHC observation would be difficult. Double diffractive di-photon production, however, should be observable within one year of Tevatron Run II. 1 Introduction With the start of Run II at the Tevatron the possibility of detecting a light higgs boson has of course been the focus of much attention. One suggested experimentally clean search strategy is to look in double diffractive collisions in which the final state contains only intact protons, which escape the central detectors, and the decay products of the higgs, in this case two b quark jets. The protons would be tagged in roman pot detectors a long way down stream of the interaction point, allowing a very precise determination of the higgs mass, using the so-called missing mass method [1]. With such proton tagging, the available center of mass energy of up to 200 GeV means that the preferred higgs mass of around 115 GeV is kinematically accessible, at least in principle. -

Brian Cox and Professor Jeff Forshaw go on a journey to the frontier of twenty-first century science to unpack Einstein's famous equation. Explaining and simplifying notions of energy, mass, and light-while exploding commonly held misconceptions-they demonstrate how the structure of nature itself is contained within this equation. Along the way, we visit the site of one of the largest scientific experiments ever conducted: the now-famous Large Hadron Collider, a gigantic particle accelerator capable of re-creating conditions that existed fractions of a second after the Big Bang. Jeff Forshaw is a Professor of Theoretical Physics at the University of Manchester, specializing in the physics of elementary particles.

Soft Gluons and Non-Global Observables Mike Seymour – University of Manchester / CERN TH on Behalf of Rene Angeles Martinez, Matthew De Angelis, Jeffrey R
Soft Gluons and Non-global Observables Mike Seymour – University of Manchester / CERN TH on behalf of Rene Angeles Martinez, Matthew De Angelis, Jeffrey R. Forshaw, Simon Plätzer, Michael H. Seymour based on JHEP 05 (2018) 044 (arxiv:1802.08531) Soft gluon evolution • In particular, how does soft gluon emission affect subsequent soft gluon evolution? Soft Gluons and Non-global Observables • Soft gluon emission evolution algorithm • An IR-finite reformulation • The ordering variable • Colour flow basis • (Towards) an exact numerical implementation • (“amplitude-level parton shower”) et al [14], as well as Weigert and Caron-Huot [7, 11, 30]. In Appendix B we make the can- cellation of infrared divergences explicit for observables that are inclusive below a resolution scale, and in Appendix C we explicitly calculate contributions in a fixed-order expansion. Finally, Appendix D sets up the machinery to deal with the fact that most colour bases are not orthogonal (see [31] for a notable exception). 2Thegeneralalgorithm Our starting point is the cross section for emitting n soft gluons. At this stage we will assume that it is ok to order successive emissions in energy. This assumption is ok for processes that are insensitive to Coulomb gluon exchanges but appears not to be valid otherwise [29, 32].
