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…
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…
Gravitational solitons and non-relativistic string theory
Troels Harmark, Johannes Lahnsteiner, Niels A. Obers
We explore the non-relativistic string theory (NRST) limit of type II string theory and its action on gravitational solitons. As a start, we exhibit in detail that the NRST limit i…
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…
