A positive energy theorem for asymptotically de Sitter spacetimes
DE sitter spacetime conserved DE sitter universe spinor and energy
2014/12/22
We construct a set of conserved charges for asymptotically de Sitter spacetimes that correspond to asymptotic conformal isometries. The charges are given by boundary integrals at spatial infinity in t...

De Nederlandse Natuurkundige Vereniging (NNV) is al sinds 1921 dé belangenbehartiger van de natuurkunde in Nederland. De NNV komt op voor de discipline natuurkunde in het voortgezet onderwijs, het hog...
Huygens' Principle for the Klein-Gordon equation in the de Sitter spacetime
Huygens’ Principle Klein-Gordon Equation de Sitter spacetime Higuchi Bound
2012/6/14
In this article we prove that the Klein-Gordon equation in the de Sitter spacetime obeys the Huygens' principle if and only if the physical mass $m$ of the scalar field and the dimension $n$ of the sp...
Anti de Sitter quantum field theory and a new class of hypergeometric identities
hypergeometric identities High Energy Physics - Theory Anti de Sitter quantum field theory
2011/10/9
Abstract: We use Anti-de Sitter quantum field theory to prove a new class of identities between hypergeometric functions related to the K\"all\'en-Lehmann representation of products of two Anti-de Sit...
de Broglie waves as the "Bridge of Becoming" between quantum theory and relativity
de Broglie waves quantum theory and relativity quantum level
2011/8/16
Abstract: It is hypothesized that de Broglie's 'matter waves' provide a dynamical basis for Minkowski spacetime in an antisubstantivalist or relational account. The relativity of simultaneity is seen ...
Andreev reflection and the semiclassical Bogoliubov-de Gennes Hamiltonian: resonant states

Abstract: We present a semi-classical analysis of the opening of superchannels in gated mesoscopic SNS junctions. For perfect junctions (i.e. hard-wall potential), this was considered by Chtchelkatche...

Conformal field theories in anti-de Sitter space
Conformal field theories anti-de Sitter space
2010/12/24
In this paper we discuss the dynamics of conformal field theories on anti-de Sitter space, focussing on the special case of the N=4 supersymmetric Yang-Mills theory on AdS_4. We argue that the choice...
We give an interpretation of the temperature in de Sitter universe in terms of a dynamical Unruh effect associated with the Hubble sphere. As with the quantum noise perceived by a uniformly accelerate...
One-loop quantum cosmological correction to the gravitational constant using the kink solution in de Sitter universe
One-loop correction kink energy shape invariance zeta func-tion regularization
2010/12/20
In this paper, we show the equivalence between a classical static scalar field theory and the (closed) de Sitter cosmological model whose potential represents shape invariance property.

Cosmological models with a de Sitter 3-brane embedded in a five-dimensional de Sitter spacetime
(dS5) give rise to a finite 4D Planck mass similar to that in Randall-Sundrum (RS) brane-world

We explore in detail the prospects of obtaining a four-dimensional de Sitter universe in classical supergravity models with warped and time-independent extra dimensions,presenting explicit cosmologica...
We apply the nonstandard loop quantum cosmology method to quan-tize a flat FRW cosmological model with a free scalar field and the cosmological constant Λ > 0. Modification of the Hamiltonian in terms...
Breaking of de Sitter Symmetry
de Sitter Symmetry
2010/12/21
We show that an interacting spin-0 field on a de Sitter space backgroundwill break the underlying de Sitter symmetry. This is done first for a (1+1) de Sitter space where a boson-fermion correspondenc...
To one loop order, interacting boson fields on de Sitter space have an “infrared” anomaly that breaks the de Sitter symmetry for all vacua save the Euclidian one. The divergence of a symmetry current ...
