Dark Energy from the Fifth Dimension
A. Stern, Chuang Xu
After extending the Regge-Teitelboim formulation of gravity to include the case where the background embedding space is not flat, we examine the dynamics of the four-dimensional $k…
Cosmic acceleration in Regge-Teitelboim gravity
S. Fabi, A. Stern, Chuang Xu
The Regge-Teitelboim formulation of gravity, which utilizes dynamical embeddings in a background space, effectively introduces source terms in the standard Einstein equations that…
Exact solutions for scalars and spinors on quantized (Euclidean) and the correspondence principle
A. Pinzul, A. Stern
We obtain the exact solutions to the field equations for massless scalar and massless spinor fields on quantized two-dimensional anti-de Sitter space. We then apply the AdS/CFT cor…
Asymptotic commutativity of quantized spaces: the case of
Fedele Lizzi, A. Pinzul, A. Stern +1
We present a procedure for quantizing complex projective spaces , , as well as construct relevant star products on these spaces. The quantization is made…
Lagrangian formulation for electric charge in a magnetic monopole distribution
G. Marmo, Emanuela Scardapane, A. Stern +2
We give a Lagrangian description of an electric charge in a field sourced by a continuous magnetic monopole distribution. The description is made possible thanks to a doubling of t…
Non-commutative duality: the case of massive and interacting scalar fields
Felipe Rodrigues de Almeida, Aleksandr Pinzul, Allen Stern
We continue the study of the nocommutative correspondence. We extend our previous results obtained for a free massless scalar field to the case of a massive scalar…
