D-instantons and twistors
Sergei Alexandrov, Boris Pioline, Frank Saueressig +1
Finding the exact, quantum corrected metric on the hypermultiplet moduli space in Type II string compactifications on Calabi-Yau threefolds is an outstanding open problem. We addre…
Almost BPS black holes
Kevin Goldstein, Stefanos Katmadas
We study non-BPS black hole solutions to ungauged supergravity with 8 supercharges coupled to vector multiplets in four and five dimensions. We identify a large class of five dimen…
The Klebanov-Strassler model with massive dynamical flavors
Francesco Bigazzi, Aldo L. Cotrone, Angel Paredes +1
We present a fully backreacted D3-D7 supergravity solution dual to the Klebanov-Strassler cascading gauge theory coupled to a large number of massive dynamical flavors in the Venez…
Temperature versus acceleration: the Unruh effect for holographic models
Angel Paredes, Kasper Peeters, Marija Zamaklar
We analyse the effect of velocity and acceleration on the temperature felt by particles and strings in backgrounds relevant in holographic models. First, we compare accelerated str…
Phase transitions in large N(c) heavy quark potentials
F. Bigazzi, A. L. Cotrone, A. Paredes
We describe phase transitions in the heavy quark potential in planar gauge theories having wrapped D5-brane string duals. A new phase transition, previously unnoticed in these mode…
A new continuum limit of matrix models
J. Ambjorn, R. Loll, Y. Watabiki +2
We define a new scaling limit of matrix models which can be related to the method of causal dynamical triangulations (CDT) used when investigating two-dimensional quantum gravity.…
