Holographic deformations of matrix models
Alfred Bovon, Henning Samtleben, Dimitrios Tsimpis
We study maximal supergravity in two dimensions, obtained from reduction of IIA supergravity on an sphere. The theory captures the low-lying fluctuations around the non-confo…

Exponential Quintessence: curved, steep and stringy?
David Andriot, Susha Parameswaran, Dimitrios Tsimpis +2
We explore the possibility that our universe's current accelerated expansion is explained by a quintessence model with an exponential scalar potential, , kee…
