Intergalactic magnetic field spectra from diffuse gamma rays
Wenlei Chen, Borun D. Chowdhury, Francesc Ferrer +2
Non-vanishing parity-odd correlators of gamma ray arrival directions observed by Fermi-LAT indicate the existence of a helical intergalactic magnetic field (Tashiro et al.2013). We…
Hawking Evaporation is Inconsistent with a Classical Event Horizon at
Borun D. Chowdhury, Lawrence M. Krauss
A simple classical consideration of black hole formation and evaporation times focusing solely on the frame of an observer at infinity demonstrates that an infall cutoff outside th…
When UV and IR Collide: Inequivalent CFTs From Different Foliations Of AdS
Borun D. Chowdhury, Maulik K. Parikh
In the AdS/CFT correspondence, CFTs are identified by asymptotic boundary surfaces and the boundary conditions imposed on those surfaces. However, AdS can be foliated in various wa…
Entwinement and the emergence of spacetime
Vijay Balasubramanian, Borun D. Chowdhury, Bartlomiej Czech +1
It is conventional to study the entanglement between spatial regions of a quantum field theory. However, in some systems entanglement can be dominated by "internal", possibly gauge…
Limitations of holography
Borun D. Chowdhury
By studying global AdS using different foliations, global and Rindler-AdS, we show that there are two different asymptotic Fefferman-Graham expansions possible and thus two differe…
Non-supersymmetric Microstates of the MSW System
Souvik Banerjee, Borun D. Chowdhury, Bert Vercnocke +1
We present an analysis parallel to that of Giusto, Ross, and Saxena (arXiv:0708.3845) and construct a discrete family of non-supersymmetric microstate geometries of the Maldacena-S…
