Ising surface defects can get dirty
António Antunes, Apratim Kaviraj, Baishali Roy
Real critical systems, such as uniaxial ferromagnets in the 3d Ising universality class, are constrained by boundaries and subject to random couplings. We consider the Wilson-Fishe…
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…
Notes on heating phase dynamics in Floquet CFTs and Modular quantization
Suchetan Das, Bobby Ezhuthachan, Somnath Porey +1
In this article, we explore the connection between the heating phase of periodically driven CFTs and the Modular Hamiltonian of a subregion in the vacuum state. We show that the he…
Moving Mirrors, OTOCs and Scrambling
Parthajit Biswas, Bobby Ezhuthachan, Arnab Kundu +1
We explore the physics of scrambling in the moving mirror models, in which a two-dimensional CFT is subjected to a time-dependent boundary condition. It is well-known that by choos…
Krylov Complexity in CFTs with SL deformed Hamiltonians
Vinay Malvimat, Somnath Porey, Baishali Roy
In this study, we analyze Krylov Complexity in two-dimensional conformal field theories subjected to deformed SL Hamiltonians. In the vacuum state, we find that the…
Out-of-Time-Order correlators in driven conformal field theories
Suchetan Das, Bobby Ezhuthachan, Arnab Kundu +3
We compute Out-of-Time-Order correlators (OTOCs) for conformal field theories (CFTs) subjected to either continuous or discrete periodic drive protocols. This is achieved by an app…
Critical Quenches, OTOCs and Early-Time Chaos
Suchetan Das, Bobby Ezhuthachan, Arnab Kundu +2
In this article, we explore dynamical aspects of Out-of-Time-Order correlators (OTOCs) for critical quenches, in which an initial non-trivial state evolves with a CFT-Hamiltonian.…
Virasoro algebras, kinematic space and the spectrum of modular Hamiltonians in CFT
Suchetan Das, Bobby Ezhuthachan, Somnath Porey +1
We construct an infinite class of eigenmodes with integer eigenvalues for the Vacuum Modular Hamiltonian of a single interval in 2d CFT and study some of its interesting proper…
