Anti-de Sitter momentum space [PDF]
Physical Review D, 2015 We investigate the anti-de Sitter (AdS) counterpart to the well-studied de Sitter (dS) model for energy-momentum space, viz ``$\ensuremath{\kappa}$-momentum space'' space (with a structure based on the properties of the $\ensuremath{\kappa}$-Poincar\'e Hopf algebra).

Holography in de Sitter and anti-de Sitter spaces and Gel'fand Graev Radon transform
Physics Letters B, 2019 Bulk reconstruction formulas similar to HKLL are obtained for de Sitter and anti-de Sitter spaces as the inverse Gel'fand Graev Radon transform. While these generalize our previous result on the Euclidean anti-de Sitter space, their validity in here is ...

Analytical evaluation of cosmological correlation functions
Journal of High Energy Physics, 2022 Using the Schwinger-Keldysh-formalism, reformulated in [1] as an effective field theory in Euclidean anti-de Sitter, we evaluate the one-loop cosmological four-point function of a conformally coupled interacting scalar field in de Sitter.

Chaos and complementarity in de Sitter space
Journal of High Energy Physics, 2020 We consider small perturbations to a static three-dimensional de Sitter geometry. For early enough perturbations that satisfy the null energy condition, the result is a shockwave geometry that leads to a time advance in the trajectory of geodesics ...

Mesons from global anti-de Sitter space [PDF]
Journal of High Energy Physics, 2011 In the context of gauge/gravity duality, we study both probe D7-- and probe D5--branes in global Anti-de Sitter space. The dual field theory is N=4 theory on R x S^3 with added flavour. The branes undergo a geometrical phase transition in this geometry as function of the bare quark mass m_q in units of 1/R with R the S^3 radius.

Super algebra and Harmonic Oscillator in Anti de Sitter space [PDF]
Iranian Journal of Astronomy and Astrophysics, 2019 The harmonic oscillator in anti de Sitter space(AdS) is discussed. We consider the harmonic oscillator potential and then time independent Schrodinger equation in AdS space.

Supersymmetry in anti-de Sitter space [PDF]
Annals of Physics, 1986 We consider the Wess-Zumino model in a background anti-de Sitter space- time in four dimensions (AdS)4. We show that the naive generators of the O(3,2) isometry group, obtained by the Noether method, must be improved by adding surface terms. The improved generators have a manifestly positive definite energy density, are conserved, and have vanishing ...
