A Note on Particles and Scalar Fields in Higher Dimensional Nutty Spacetimes

In this note, we study the integrability of geodesic flow in the background of a very general class of spacetimes with NUT-charge(s) in higher dimensions. This broad set encompasses multiply NUT-charged solutions, electrically and magnetically charged solutions, solutions with a cosmological constant, and time dependant bubble-like solutions. We also derive first-order equations of motion for particles in these backgrounds. Separability turns out to be possible due to the existence of non-trivial irreducible Killing tensors. Finally, we also examine the Klein-Gordon equation for a scalar field in these spacetimes and demonstrate complete separability.Comment: Accepted for Publication in Phys. Lett. B., 11 Page

Energy – the not-so bottomless oil well and the alternatives

This essay examines both sides of the “Hubbert’s peak” debate and their implications for energy policy. If there is a strong case for governments to wean their economies of oil, how do they do it? What low-carbon or alternative technologies bear watching? How will these technologies affect the environment? How long will the world remain reliant on oil considering that industries are 98% dependent on petroleum products

Stories as capacious objects : narratives of belonging in LGBT community in Chennai, India

This report grows out of my observations and fieldwork notes made in the summer of 2014 in Chennai, India. It argues that when faced with conflicting pulls, varied levels of visibility and state recognition, and multiple axes of privileges, disenfranchisement and suffering, some members of the LGBT community in Chennai emphasized the importance of an additional set of implicit criteria for what constitutes solidarity: showing up; doing the work; making a timely gesture of support or help; being present in a moment of crisis; having shared experiences of fun, outrage, suffering, etc. They used narratives to emphasize friendships and longevity of associations across sexual orientation, gender identity, class, caste, etc., as a way to ameliorate the anxieties created by the questioning of solidarities. My claim is not that such a focus on relationships across social divides directly challenges or carries the potential to challenge larger social orders of gender, class, or caste in a systematic way. My desire, instead, is to focus on the very urge felt by actors involved to ameliorate through narratives the questioning of the legitimacy of the idea of a community. My aim has been to understand what attitudes to relationships and solidarities and what kinds of connections, affect, and slantedness towards one another these exercises reveal.Anthropolog
