Emergent Lifshitz scaling from N=4 SYM with supersymmetric heavy-quark density
Anton F. Faedo, Benjo Fraser, S. Prem Kumar
We consider supersymmetric configurations in Type IIB supergravity obtained by the beackreaction of fundamental strings ending on a stack of D3-branes and smeared uniformly in the…
Non-perturbative results for large-N gauge theories
Biagio Lucini
It has been known for a long time that large- methods can give invaluable insights into non-perturbative phenomena such as confinement. Lattice techniques can be used to compute…
Conformal perturbation theory and higher spin entanglement entropy on the torus
Shouvik Datta, Justin R. David, S. Prem Kumar
We study the free fermion theory in 1+1 dimensions deformed by chemical potentials for holomorphic, conserved currents at finite temperature and on a spatial circle. For a spin-thr…
Gravitational leptogenesis, C, CP and strong equivalence
J. I. McDonald, Graham M. Shore
The origin of matter-antimatter asymmetry is one of the most important outstanding problems at the interface of particle physics and cosmology. Gravitational leptogenesis (baryogen…
A scenario for inflationary magnetogenesis without strong coupling problem
Gianmassimo Tasinato
Cosmological magnetic fields pervade the entire universe, from small to large scales. Since they apparently extend into the intergalactic medium, it is tantalizing to believe that…
Type IIB Supergravity Solutions with AdS From Abelian and Non-Abelian T Dualities
Niall T. Macpherson, Carlos Núñez, Leopoldo A. Pando Zayas +2
We present a large class of new backgrounds that are solutions of type IIB supergravity with a warped AdS factor, non-trivial axion-dilaton, -field and three-form Ramond-R…
