Low-temperature Quantum-corrected Holographic Transport with Momentum Relaxation
Suman Das, Sabyasachi Maulik, Leopoldo A. Pando Zayas +1
We determine the quantum corrections to transport arising from fluctuations of the near-AdS throat of near-extremal black branes in holographic models with momentum relaxatio…
Cosmological brick walls & quantum chaotic dynamics of de Sitter horizons
José M. Begines, Suman Das, Hyun-Sik Jeong +1
Originally proposed by 't Hooft, the brick wall model has recently reemerged as a useful framework for probing quantum aspects of horizon physics, particularly in the context of ho…
Blackish Holes with Stringy Backreaction
Elena Cáceres, Suman Das, Arnab Kundu +1
Recent studies have demonstrated that an Dirichlet boundary condition, placed outside but close to an event horizon, for probe degrees of freedom in an otherwise…
Blackish Holes
Souvik Banerjee, Suman Das, Arnab Kundu +1
Based on previous works, in this article we systematically analyze the implications of the explicit normal modes of a probe scalar sector in a BTZ background with a Dirichlet wall,…
Brick Wall in AdS-Schwarzschild Black Hole: Normal Modes and Emerging Thermality
Suman Das, Somnath Porey, Baishali Roy
This paper investigates the normal modes of a probe scalar field in a five-dimensional AdS-Schwarzschild black hole with the brick wall boundary condition near the horizon. We empl…
Brickwall, Normal Modes and Emerging Thermality
Souvik Banerjee, Suman Das, Moritz Dorband +1
In this article, we demonstrate how black hole quasi-normal modes can emerge from a Dirichlet brickwall model normal modes. We consider a probe scalar field in a BTZ geometry with…
Brickwall in Rotating BTZ: A Dip-Ramp-Plateau Story
Suman Das, Arnab Kundu
In this article, building on our recent investigations and motivated by the fuzzball-paradigm, we explore normal modes of a probe massless scalar field in the rotating BTZ-geometry…
What is the Simplest Linear Ramp?
Suman Das, Sumit K. Garg, Chethan Krishnan +1
We discuss conditions under which a deterministic sequence of real numbers, interpreted as the set of eigenvalues of a Hamiltonian, can exhibit features usually associated to rando…
Synthetic Fuzzballs: A Linear Ramp from Black Hole Normal Modes
Suman Das, Chethan Krishnan, A. Preetham Kumar +1
We consider a black hole with a stretched horizon as a toy model for a fuzzball microstate. The stretched horizon provides a cut-off, and therefore one can determine the normal (as…
