Quantum Fields and the Cosmological Constant
UniverseIt has been shown that if one solves self-consistently the semiclassical Einstein equations in the presence of a quantum scalar field, with a cutoff on the number of modes, spacetime become flatter when the cutoff increases. Here, we extend the result to

Journal of the Royal Anthropological Institute, EarlyView.Food and alcohol indulgence, along with tea‐drinking, gambling, and gossip, are integral to a characteristically Sichuanese ethos of ‘life enjoyment’ (xiangshou shenghuo). Beyond mere pleasure, sensory, ludic, and comic experiences temporarily strip participants of both their formal and subjective qualities.

, 2007 We propose cosmological redshift-space distortion of correlation functions of galaxies and quasars as a useful probe of both the density parameter\Omega 0 and the cosmological constant 0 .

Varying Constants, Gravitation and Cosmology [PDF]
Living Reviews in Relativity, 2011 Abstract Fundamental constants are a cornerstone of our physical laws. Any constant varying in space and/or time would reflect the existence of an almost massless field that couples to matter. This will induce a violation of the universality of free fall.

The Big Picture: Religion and Global Comparative History
Journal of Religious History, EarlyView.This article considers what a ‘big picture’ approach to global religious history might look like, and in particular the implications of deploying the comparative method across much larger stretches of time and space than historians normally attend to. It will begin by reflecting on the epistemological moods that have hindered this project to date, the ...

GHOSTLY ENCOUNTERS IN LAGOS: Virtual Reality between Urban Marketing and Media Activism
International Journal of Urban and Regional Research, EarlyView.Abstract This article examines the role of virtual reality (VR) technologies in mediating and contesting dominant visions of urban futures in West Africa. Drawing on theoretical insights from a hybridization of the work of the German‐born Jewish critic Walter Benjamin and the Nigerian writer Amos Tutuola, I introduce the concept of phantasmagoria as a ...

The Cosmological parameter: constant or dynamical
, 2022 After providing a brief history of the cosmological constant, some early cosmological models are discussed. The most popular current cosmological model is the ΛCDM model, but there are several problems associated with this model, e.g., the cosmological ...

COSMOLOGICAL PERTURBATIONS AND THE RUNNING COSMOLOGICAL CONSTANT MODEL [PDF]
International Journal of Modern Physics D, 2012 We study the matter density fluctuations in the running cosmological constant (RCC) model using linear perturbations in the longitudinal gauge. Using this observable, we calculate the growth rate of structures and the matter power spectrum, and compare these results to SDSS data and the available data for linear growth rate.

International Journal of Urban and Regional Research, EarlyView.Abstract This article investigates the symbolic politics of state‐led gentrification and heritagization, focusing on how these processes serve to ‘glorify’ state power. Drawing on Agamben's political theology, Bourdieu's notion of symbolic power and space, and political heritage studies, we argue that the symbolic politics of state glorification can ...
