Of Matters Condensed

چکیده
The American Physical Society (APS) March Meeting of condensed matter physics has grown to nearly 10,000 participants, comprises 23 individual APS groups, and even warrants its own hashtag (#apsmarch). Here we analyze the text and data from March Meeting abstracts of the past nine years and discuss trends in condensed matter physics over this time period. We find that in comparison to atomic, molecular, and optical physics, condensed matter changes rapidly, and that condensed matter appears to be moving increasingly toward subject matter that is traditionally in materials science and engineering. Introduction Condensed matter physics studies beautiful fundamental physics, such as superconductivity, while simultaneously providing important inventions including the transistor, CCD, integrated circuit and diode laser. Moreover, the field holds promise for future applications, such as dissipationless power transfer and quantum information processing. The American Physical Society (APS) March Meeting is arguably the largest condensed matter physics conference and attracts nearly 10,000 participants to a single location to discuss the topic. These participants include undergraduate students, graduate students, postdocs, staff scientists, professors, engineers, vendors of scientific instruments, and journalists both from around the world. Sessions include numerous contributed talks, posters, invited talks, (so-called “crackpot” sessions), and exhibits, and provides all physics enthusiasts an opportunity to deepen their knowledge of their respective fields of specialization, as well as to gain exposure to new, emerging fields in condensed matter. The March Meeting, therefore, offers a snapshot of progress in the represented fields, and is a good measure of the trends in condensed matter. We scraped the abstract content from the March Meeting programs from 2007-2015 to examine and analyze these trends, and speculate about the future of matters condensed. Some simple numbers We begin with the most basic of trends. The field of condensed matter, as measured by the number of contributed abstracts to the March Meeting has shown steady growth since 2007 (Figure 1a). This finding is somewhat surprising, given the sentiment that interest in condensed matter was inflated by the discoveries of the 50’s, 60’s and 70’s, and has subsequently begun to wane. In fact, as measured by arxiv submissions, the growth of condensed matter has slowed, and its relative contribution to the entire arxiv pool has steadily dropped since approximately 2002. The steady growth of abstracts in the presence of a decrease in arxiv submissions can be attributed either to submissions of historically “cond-mat” articles to other areas (such as “quant-phys”), or to an increase in unpublishable abstract submissions. However, our expertise is in only a small subset of March Meeting and condensed matter fields, and we therefore cannot adequately judge the publishability of results. Lastly, we note remarkable consistency in both the length (in words) and number ∗[email protected] 1http://arxiv.org/help/stats/2014 by area/index 1 ar X iv :1 50 2. 03 10 3v 1 [ ph ys ic s. so cph ] 1 0 Fe b 20 15

An experiment was conducted to investigate the effect of molasses distillers condensed soluble (MDCS) on growth performance, carcass characteristics and intestinal morphology of broilers. A total of 400 one day-old, unsexed Ross 308 broiler chicks were randomly allotted to 20 cages. The dietary MDCS levels incorporated 0% and 4% in the starter and 0%, 4% and 8% in grower diet, respectively. The...

An optical system has been redesigned and used to measure detonation velocity as a function of condensed explosive density for RDX, HMX, PETN. These measurements are then used to determine and fine tune parameters appearing in the BKW (Beker-Kistiakowsky-Wilson) equation of state for gases at extremely high pressures. Steady state form of conservation equations along with the BKW state equation...
