Seeing double: shock waves and the de Sitter horizon
Willy Fischler, Hare Krishna, Sarah Racz
We consider a de Sitter observer in his rest frame at late times who observes a particle slightly displaced from unstable equilibrium. Initially, the observer notices an axisymmetr…
There is more to the de Sitter horizon than just the area
Willy Fischler, Hare Krishna, Sarah Racz
It is well known that the area of the de Sitter cosmological horizon is related to the entropy of the bulk spacetime. Recent work has however shown that the horizon encodes more in…
Topologically charged BPS microstates in AdS/CFT
Arash Arabi Ardehali, Hare Krishna
In the standard AdS/CFT with , as well as the Datta-Eberhardt-Gaberdiel variant with $\mathrm{sym}^N(T^4/\mathb…
Light-Cone Reduction vs. TsT transformations : A Fluid Dynamics Perspective
Suvankar Dutta, Hare Krishna
We compute constitutive relations for a charged dimensional Schrödinger fluid up to first order in derivative expansion, using holographic techniques. Starting with a local…
