ORII Tcm. PAOE T5 of POOR QUALITY Wide-Bandwidth High

PAOE t5 OF POOR QUALITY Wide-Bandwidth High-Resolution Search for Extraterrestrial Intelligence Semiannual Status Report l_c 1992 -- 15 June 1993 Paul Horowitz, Principal Investigator Harvard University Cambridge, MA 02138 June 15, 1993 Grant Number NAGW-2872 (NASA-CR-I93137) WIDE-BANDWIDTH N93-28895 HIGH-RESOLUTION SEARCH FOR EXTRATERRESTRIAL INTELLIGENCE Semiannual Status Report, 15 Dec. Uncl as 1992 - 15 Jun. 1993 {Harvard Univ.) 26 p G3/55 0167880 1. INTRODUCTION This report summarizes research accomplished during the third 6-month period of the grant. During the period covered by this report the active personnel included the PI, three graduate students (Darren Leigh, Rik Koda, and Jonathan Weintroub, each averaging a quarter-time research commitment), a Harvard undergraduate (Derrick Bass), and a recent mathematics graduate from Harvard (Nick Shectman). 2. RESEARCH ACCOMPLISHED 2.1 Dual-Horn Antenna Performance As described in the previous progress report, we designed, built, and installed a pair of stacked pyramidal horns. The design was a compromise, with a reduced edge taper of 5.5dB (compared with the canonical 10dB). This was done in order to increase beam lobe overlap, and to permit two horns to fit in the existing radome, which was originally built to hold a single conical horn. We took the unusual step of truncating the corners (see Figure 4 in the previous report), to allow a larger horn aperture within the constraints of a cylindrical radome. Our calculations predicted only a 0.6dB loss of antenna efficiency, and a point-source crossover at the -4dB point; we assumed no feedhorn interactions. -

As digital technologies are expanding the power and reach of research, they are also raising complex issues. These include complications in ensuring the validity of research data; standards that do not keep pace with the high rate of innovation; restrictions on data sharing that reduce the ability of researchers to verify results and build on previous research; and huge increases in the amount of data being generated, creating severe challenges in preserving that data for long-term use. Ensuring the Integrity, Accessibility, and Stewardship of Research Data in the Digital Age examines the consequences of the changes affecting research data with respect to three issues - integrity, accessibility, and stewardship-and finds a need for a new approach to the design and the management of research projects. -

In Memory of Leo P. Kadanoff
Journal of Statistical Physics manuscript No. (will be inserted by the editor) Franz J. Wegner In memory of Leo P. Kadanoff Received: Accepted: Abstract Leo Kadanoff has worked in many fields of statistical mechanics. His contributions had an enormous impact. This holds in particular for critical phe- nomena, where he explained Widom’s homogeneity laws by means of block-spin transformations and laid the basis for Wilson’s renormalization group equation. I had the pleasure to work in his group for one year. A short historically account is given. Keywords Renormalization group · Block-spin transformation · Critical phenomena · Ising Model · Duality 1 Introduction Leo Kadanoff has worked in many fields of Statistical Mechanics. He started out in working on superconductivity in a thesis under the supervi- sion of Paul Martin at Harvard. Leo and Gordon Baym developed self-consistent approximations which preserved the conservation laws[4]. They published the widely used book Conservation laws and correlation functions[34]. Gordon Baym has reviewed his time with Leo in his contribution Conservation laws and the quantum theory of transport: The early days.[3] After a number of papers related to superconductivity and transport phenom- ena he became interested in critical phenomena, where he contributed essentially. Section 2 reviews shortly the situation in this field in the fifties and sixties of the last century. Section 3 reviews the contributions of Ben Widom and Leo Kadanoff in 1965 and 1966, which were two important steps in the understanding of this field. This led to a strongly growing interest in this field (sect. 4). Finally, in 1971 Ken Wilson developed the tool to calculate explicitly the critical behavior. -

However, while the government almost appeared to slow to a halt during the transition, news of exciting physics research results continued unabated. During the APS March Meeting in Seattle, a marathon session was held on the new superconductor, magnesium diboride, while at the April Meeting in Washington, DC, excitement was high as the first reports of new precision measurements of the cosmic microwave background strongly supported the idea of an early inflationary universe. Other lead stories included the Sudbury Neutrino Observatory (SNO) results confirming solar neutrino oscillations, the establishment of CP violation in B-meson decay, and the demonstration of bringing pulses of light to a standstill in such a way that all of the information that they contain is stored in atomic excitations and later recoverable. Heroic efforts by the APS Editorial Office staff throughout the year allowed the completion of the Physical Review On-line Archive, PROLA, so that every paper that APS has ever published is now on-line and readily accessible. Within PROLA, each paper is linked to previous papers to which it refers and also to subsequent papers that cite it. -

Pushing it toward earlier or later dates will result in conflicts with teaching for many of the potential attendees. __________________________________________________________ Abstract: Quantum computers, if realized in practice, promise exponential speed-up of some of the computational tasks that conventional classical algorithms are intrinsically incapable of handling efficiently. Perhaps even more intriguing possibility arises from being able to use quantum computers to simulate the behavior of other physical systems -- an exciting idea dating back to Feynman. Unfortunately, realizing a quantum computer in practice proves to be very difficult, chiefly due to the debilitating effects of decoherence plaguing all possible schemes which use microscopic degrees of freedom (such as nuclear or electronic spins) as basic building blocks. >From this perspective, topological quantum computing offers an attractive alternative by encoding quantum information in nonlocal topological degrees of freedom that are intrinsically protected from decoherence due to local noise. -
