Non-relativistic Floquet Conformal Field Theory
Diptarka Das, Sumit R. Das, Arnab Kundu +1
We develop a formalism for studying Floquet dynamics for systems with non-relativistic conformal invariance in d spatial dimensions. Our analysis indicates the existence of two dyn…
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…
Dynamical Phases of Higher Dimensional Floquet CFTs
Diptarka Das, Sumit R. Das, Arnab Kundu +1
This paper investigates the dynamical phases of Floquet Conformal Field Theories (CFTs) in space-time dimensions greater than two. Building upon our previous work [1] which introdu…
Flowery Horizons & Bulk Observers: Drive in Holographic CFT
Jayashish Das, Arnab Kundu
We explore and analyze bulk geometric aspects corresponding to a driven two-dimensional holographic CFT, where the drive Hamiltonian is constructed from the $sl^{(q)}(2,\mathbb{R})…
Brickwall One-Loop Determinant: Spectral Statistics & Krylov Complexity
Hyun-Sik Jeong, Arnab Kundu, Juan F. Pedraza
We investigate quantum chaotic features of the brickwall model, which is obtained by introducing a stretched horizon - a Dirichlet wall placed outside the event horizon - within th…
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,…
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…
Exactly Solvable Floquet Dynamics for Conformal Field Theories in Dimensions Greater than Two
Diptarka Das, Sumit R. Das, Arnab Kundu +1
We find classes of driven conformal field theories (CFT) in d + 1 dimensions with d > 1, whose quench and Floquet dynamics can be computed exactly. The setup is suitable for studyi…
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…
