Carroll Geometry Meets De Sitter Space via Holography
Chris D. A. Blair, Niels A. Obers, Ziqi Yan
We explain how to relate the ideas of Carroll geometry, matrix theory on instantonic objects, and infinite boost limits of M-theory. Based on these new insights, we explore the imp…
Dual Non-Lorentzian Backgrounds for Matrix Theories
Chris D. A. Blair, Johannes Lahnsteiner, Niels A. Obers +1
We study properties of non-Lorentzian geometries arising from BPS decoupling limits of string theory that are central to matrix theory and the AdS/CFT correspondence. We focus on d…
Supersymmetric solutions of non-relativistic 11-dimensional supergravity
Chris D. A. Blair
Eleven-dimensional supergravity has a non-relativistic variant obtained by taking a limit associated with the M2 brane. Consistency of this non-relativistic supergravity requires c…
The surprising structure of non-relativistic 11-dimensional supergravity
Eric A. Bergshoeff, Chris D. A. Blair, Johannes Lahnsteiner +1
We study a non-relativistic limit of 11-dimensional supergravity. This limit leads to a theory with an underlying membrane Newton-Cartan geometry. Consistency of the non-relativist…
Matrix Theory Reloaded: A BPS Road to Holography
Chris D. A. Blair, Johannes Lahnsteiner, Niels A. Obers +1
We revisit the decoupling limits that lead to matrix theories on D-branes. We highlight the BPS nature of these limits, in which the target space geometry becomes non-Lorentzian an…
Unification of Decoupling Limits in String and M-theory
Chris D. A. Blair, Johannes Lahnsteiner, Niels A. Obers +1
We study and extend the duality web unifying different decoupling limits of type II superstring theories and M-theory. We systematically build connections to different corners, suc…
