The Formation of non-Keplerian Rings of Matter about Compact Stars

The formation of energetic rings of matter in a Kerr spacetime with an outward pointing acceleration field does not appear to have previously been noted as a relativistic effect. In this paper we show that such rings are a gravimagneto effect with no Newtonian analog, and that they do not occur in the static limit. The energy efficiency of these rings can, depending of the strength of the acceleration field, be much greater than that of Keplerian disks. The rings rotate in a direction opposite to that of compact star about which they form. The size and energy efficiency of the rings depend on the fundamental parameters of the spacetime as well as the strength the acceleration field.Comment: 19 pages, 7 figures, 1 diagram.

CP violation in the two-Higgs-doublet model: an example

In a general two-scalar-doublet model without fermions, there is a unique source of CP violation, $J_1$, in the gauge interactions of the scalars. It arises in the mixing of the three neutral physical scalars $X_1$, $X_2$ and $X_3$. CP violation may be observed via different decay rates for $X_1 \rightarrow H^+ W^-$ and $X_1 \rightarrow H^- W^+$ (or, alternatively, for $H^+ \rightarrow X_1 W^+$ and $H^- \rightarrow X_1 W^-$ --- depending on which decays are kinematically allowed). I compute the part of those CP-violating decay-rate differences which is proportional to $J_1$. The CP-invariant final-state-interaction phase is provided by the absorptive parts of the one-loop diagrams. I check the gauge invariance of the whole calculation.Comment: 13 pages LATEX, a bunch of figures that I can mail to you if you ask me as soon as you finish reading this (because afterwards I'll be in vacation

Beyond the Circle of Life

It seems certain to me that I will die and stay dead. By “I”, I mean me, Greg Nixon, this person, this self-identity. I am so intertwined with the chiasmus of lives, bodies, ecosystems, symbolic intersubjectivity, and life on this particular planet that I cannot imagine this identity continuing alone without them. However, one may survive one’s life by believing in universal awareness, perfection, and the peace that passes all understanding. Perhaps, we bring this back with us to the Source from which we began, changing it, enriching it. Once we have lived – if we don’t choose the eternal silence of oblivion by life denial, vanity, indifference, or simple weariness – the Source learns and we awaken within it. Awareness, consciousness, is universal – it comes with the territory – so maybe you will be one of the few prepared to become unexpectedly enlightened after the loss of body and self. You may discover your own apotheosis – something you always were, but after a lifetime of primate experience, now much more. Since you are of the Source and since you have changed from life experience and yet retained the dream of ultimate awakening, plus you have brought those chaotic emotions and memories back to the Source with you (though no longer yours), your life & memories will have mattered. Those who awaken beyond the death of self will have changed Reality

Using Twitter in university research, teaching and impact activities: a guide for academics and researchers

Twitter is a form of free micro-blogging which allows users to send and receive short public messages called tweets. Tweets are limited to no more than 140 characters, and can include links to blogs, web pages, images, videos and all other material online. You can start tweeting in 10 minutes, anytime, from your computer, smart phone or tablet.By following other people and sources you are able to build up an instant, personalized Twitter feed that meets your full range of interests, both academic and personal. Thousands of academics and researchers at all levels of experience and across all disciplines already use Twitter daily, alongside more than 200 million other users.Yet how can such a brief medium have any relevance to universities and academia, where journal articles are 3,000 to 8,000 words long, and where books contain 80,000 words? Can anything of academic value ever be said in just 140 characters?This guide answers these questions, showing you how to get started on Twitter and showing you how Twitter can be used as a resource for research, teaching and impact activities

Everett's Theory of the Universal Wave Function

This is a tutorial for the many-worlds theory by Everett, which includes some of my personal views. It has two main parts.The first main part shows the emergence of many worlds in a universe consisting of only a Mach-Zehnder interferometer. The second main part is an abridgment of Everett's long thesis, where his theory was originally elaborated in detail with clarity and rigor. Some minor comments are added in the abridgment in light of recent developments. Even if you do not agree to Everett's view, you will still learn a great deal from his generalization of the uncertainty relation, his unique way of defining entanglement (or canonical correlation), his formulation of quantum measurement using Hamiltonian, and his relative state.Comment: 18 pages, 3 figure

College Author Reception Opening Remarks

Welcome to Musselman Library! We are excited to host this celebration of scholarly work with our colleagues in the Provost’s Office. Thank you to Upscale for kicking this off. Nothing says “party” like acapella. We’re glad you’re here today. Thank you also to the team of people who made this event possible – to the Library Exhibits and Events Committee, which is chaired beautifully by Kate Martin and also includes Jim Ramos, Lisa McNamee, Donna Skekel, Carolyn Sautter, Susan Pinckey, and Becky Strevig. Becky had a baby a month ago, and Sarah Appedu has been filling in for her and taking care of a multitude of large and small things. Also thanks to Suzanne Gockowski for coordinating with the Provost’s Office and Ryan Nadeau for corralling all these publications that surround us. (excerpt

A Perspective Distilled from Seventy Years of Research

Physical organic chemistry might be regarded as officially recognized as a distinct discipline through the publication of L. P. Hammett’s book of that title, although substantial earlier work can be traced back to the turn of the 20th century. Many of the instrumental tools that helped the discipline develop in so many different ways began to appear in the late thirties and during World War II and were soon built to be increasingly operated in the “hands-on” mode. This development became very popular in academia, where instruments are not operated for you by an expert, but even if you are an undergraduate, you can more or less be the expert yourself and take many varieties of data on instruments usually available on a 24 h basis. It has been my privilege and joy to begin research in chemistry just as these waves of change began to grow and to savor the great contribution that the new methods, such as measurement of 14C, UV−vis, IR, NMR, and hands-on use of computers, made in facilitating our research programs at MIT and later at Caltech. Among those programs, which will be discussed, were 14C tracing of carbocation rearrangements and benzyne formation, electrical effects of substituents, Grignard reagents, synthesis of small-ring compounds, (2 + 2) cycloaddition reactions of halogenated ethylenes, assisting in development of ^(19)F, ^(13)C, and ^(15)N NMR for conformational analysis, other structural, kinetic, and tracer studies, as well as helping through textbooks to bring Hückel MO theory and the elements of NMR to familiarity for organic chemists. From the very beginning of my research career, I have been the beneficiary of personal mentoring which has been very crucial to my success in research and is an important theme in what follows
